True Blue Flowers: 12 Of The Best And Brightest

For centuries, people have searched for a true blue flower. Elusive and rare, it is seldom found in nature. Or, to put it another way, it is rarely perceived in nature. It all has to do with what each of us sees as blue.

To find out why, I signed up for an on-line lecture given by Brandon George, a grad student working at Cornell Botanic Gardens. His research not only produced a great list of blue flowers, but also shed some (hint) light on the issue.

WHAT CONSTITUTES BLUE

So why is blue so rare in the plant world? For starters, I’ll ask you to refer to the color wheel below.

Blue is a primary color. On the visible color spectrum, it is located between green and violet. But that’s where things get murky. Take a look at the wheel. Some blues tend towards green, while others tend towards violet. Do all of these colors merit the name blue?

At the moment, the Royal Horticultural Society (RHS) is the go-to authority. The RHS Colour Chart, created in 1966,  contains 920 pigments that can be matched precisely to flowers, fruits and other plants. Over the decades, it has become the primary means by which growers and horticulturalists communicate about colors around the world.  

Still, the color chart doesn’t explain why a true, pure blue remains so elusive. And here’s why. Though blue is a prominent color on earth, it is rarely produced in nature. In fact, of all the 280,000 known species of flowering plants, only 10 percent are blue.

HOW PLANTS PRODUCE BLUE

It turns out that plants aren’t born blue. Instead, like artists, they must mix naturally-occurring pigments to achieve their blue hue. The most common of these pigments are called anthocyanins. However, anthocyanins change their color depending on soil pH.

Hydrangea macrophylla ‘Nikko Blue’

In fact, just the tiniest tweak of metal ions in the soil can result in the same plant producing entirely different shades of blue. (Think blue hydrangeas, which are produced by adding acid to the soil.) Finding a true blue flower is really hard indeed.

WHEN PURPLE LOOKS BLUE

Even then, some of us may still see purple as blue.  Deutan Color Blindness (do-tan) is an anomaly of the ‘M’ cone (Medium Wavelength Light) in which spectral sensitivity is shifted toward longer wavelengths. If you have it, you may experience confusion between colors such as purple and blue. Take a look at the photo below. Do you see purple and blue or just blue?

TRUE BLUE PRETENDERS

Nowadays, blue flowers are highly prized. As a result, growers are introducing more and more plants that are labelled as blue. But beware – many are not truly blue! To differentiate among cultivars, horticulturalists now use the term ‘true blue’ to indicate a more true blue pigment.

Take, for instance, the hardy geranium ‘Rozanne’, a popular choice for the perennial garden. Some growers list it as violet, others lists it as blue. How do you perceive it? To my eye, it tends towards purple, while my client sees it as blue.

Hardy geranium ‘Rozanne’/Photo: anniesannuals.com

And have you ever wondered why the same blue plant can look entirely different across catalogs? Just because a plant has blue in its name doesn’t necessarily mean it’s blue. Some growers manipulate photos to make plants appear more blue. Still others use tricks of light. If you can’t see the plant in person, George recommends consulting user uploads rather than seller photos to get a better perspective on a plant’s true color.

TRUE BLUE FLOWERS

There is one plant family that typically produces the truest blue flowers in nature. Boraginaceae, also known as the forget-me-not family, includes more than 27,000 species. The plants of this family are frequently hairy and include such garden ornamentals as Virginia bluebell (Mertensia virginica), Lungwort (Pulmonaria), Forget-Me-Not (Myosotis)and Siberian Bugloss (Brunnera macrophylla). Horticulturalists agree that these are indisputable blues.

Virginia bluebells

Other indisputable blue flowers include Grape hyacinth (Muscari), Siberian squill (Scilla siberica) and Blue Drumstick allium (Azure allium), in addition to pH-sensitive Hydrangea macrophyllaNikko Blue‘, which in acidic soil (a pH below 6) will turn blue.

And don’t overlook the sky blue flowers of Siberian larkspur (Delphinium grandiflorum), and Hardy plumbago (Plumbago cerastostigma), which are all great additions to the spring/summer border.

TRUE BLUE ANNUALS

Perennials not your thing? There are some great almost-blue annuals. Evolvulus ‘Blue My Mind’ is a dwarf morning glory with fuzzy, silver-green foliage. It looks great in containers or windowboxes, where it will happily trail over the edge.

Other great true-blue annuals include Cape Plumbago (Plumbago auriculata), a very light blue, Love-In-A-Mist (Nigella), and Gentian sage (Salvia patens), a tender perennial that has the deepest blue flowers you’ll find.

DESIGNING WITH BLUE

When working with blue, remember it is considered a cool color, so it will recede into the landscape. Consider bringing it forward to enjoy it and plant cultivars in mass for a stronger effect.

But a word of caution. Placing a lot of different ‘blues’ together will often cause some to look bluer than others (see below). To prevent this from happening, separate them out and plant them instead next to contrasting colors (such as orange or yellow), which will give the illusion of a brighter blue.

How To Identify Poison Ivy

Even bad boys can have a good side; and so it goes with an unwanted inhabitant of many a garden, poison ivy.  The native plant sure knows how to take over a room. For humans, its ornamental qualities are less than desirable. That being said, poison ivy does have its uses. See below.

WHAT IT IS

According to the Centers for Disease Control and Prevention (CDC), poison ivy is one of the most common poisonous plant species found throughout the continental United States. A native of North America, it grows mostly in the eastern and midwestern states where it tends to inhabit forests, fields, and shorelines. More worrisomely, it’s also come to love urban/suburban environments such as road sides and parks. This in turn has led to it taking up residence in many of our backyards. 

Poison ivy is a member of the sumac family, Anacardiaceae, which comprises over 860 known species. Along with poison sumac and poison oak, it is part of the genus toxicodendron, whose toxic properties produce contact dermatitis in affected individuals. 

A TOXIC RELATIONSHIP

So what makes toxicodendron so toxic? The culprit is urushiol, an oily resin with allergenic properties. Urushiol is found in every part of toxicodendron, including dead or dormant plants. When poison ivy, poison oak or poison sumac are bumped, damaged or even burned, they release urushiol as a means of protection.

In fact, research shows that only a small amount of exposure can cause an allergic rash. And by small amount, that means just 1 nanogram or one billionth of a gram. There is even evidence that urushiol can remain on a surface for up to five years. The take-away? I’d say avoid these plants altogether.

On a good note, apparently about 10 to 15 percent of the human population is immune to poison ivy and its cousins, and therefore will never experience the rash. And poison ivy is less common outside the U.S., although it can still be found here and there around the globe. 

HOW TO IDENTIFY POISON IVY

A common adage says ‘Leaves of three, let it be’, while another counsels ‘Leaves of three, run and flee’. I prefer the latter, having suffered from major breakouts throughout my lifetime in the garden. That being said, poison ivy is a chameleon when it comes to appearance. it can be downright hard to identify. Compare the photo below to the two above. You’ll see what I mean.

The truth is poison ivy has so many variations it can baffle even the most seasoned horticulturalist. Take for instance its make-up. It can be a creeping groundcover, or a woody vine (referred to as a liane) which, once it scales a tree, can put on 20 feet of growth in just one season. And full sun can cause it to take on a shrub form.

And while most of us know to look out for a plant with three leaves, from that point on, things can get murky. Poison ivy has a compound leaf, which means that what presents as a single leaf is actually three. Additionally, its leaves can be shiny or dull, and their size and shape can vary greatly. Some leaves are toothed, while others are deeply lobed. And in some rare instances, poison ivy can have five leaves instead of three. 

Poison ivy taking on fall color

Look for bright green leaves during the growing season and bright red ones in the fall.

HERE’S THE RUB

The good news is that, according to the U.S. Food & Drug Administration (FDA), poison ivy rashes are not contagious and therefore cannot be spread from person to person. However, it is possible to pick up the rash from toxins stuck to clothing, tools or other items including pets (see below.) And contrary to common thought, the rash occurs only where the oil has touched the skin. So rubbing or scratching won’t spread it. What may seem like a spreading rash is actually the toxin’s effects appearing gradually over time.

Always wash your skin and clothes after coming into contact with poison ivy. This is essential to removing all traces of urushiol. And use cold water, not hot. Hot water thins the oil and helps it dissipate more quickly.

CAN ANIMALS GET POISON IVY?

According to the Pet Poison Helpline, the answer is rarely. Usually, their long protective coats prevent the plant oils from ever reaching their skin. However, animals can carry the toxin on top of their fur, so don’t let your pet rub against you if you think he or she’s been in contact. Try bathing yours with a colloidal oatmeal shampoo while wearing gloves to eliminate the urushiol.

My cat, Squeaky

IT’S GOOD FOR SOMETHING

Before you decide to remove that patch on your slope, you might want to think again. Like kudzu, poison ivy is great at erosion control, especially on coastlines where it acts as a stabilizer for sandy soil. (It’s a big player along the Eastern coastline.) Moreover, it provides valuable food for many species of wildlife, who eat its fruit, stems and leaves.  And it also functions as a protective shelter for small mammals.

Small animals like rabbits like to feed on poison ivy

WHAT TO DO ABOUT IT

As with most unwanted plants, the best way to eliminate them is to get to know their seedlings and start early. As poison ivy matures, however, it may require years of patient digging to totally eliminate its root structure.  You can apply an herbicide like glyphosate to the plant’s roots, leaves or vines. However, be sure to wear eye protection and gloves when chopping down vines. And never use a chain saw, which can spread the toxins by air.

 

 

How To Build The Perfect Monarch Butterfly Garden

monarch on pink flowers

Daniel Potter freely admits he’s not an expert on monarchs. But as Professor of Entomology at the University of Kentucky, he and his grad students sure love to run experiments. Recently, they completed a two-year study on the likes and dislikes of the popular orange and black butterfly. Now for the first time ever, there’s a roadmap for building the perfect monarch garden.

WHY WE CARE

If you’re reading this post, you’re probably already a monarch fan. The butterflies’ annual migration from Mexico to Canada is one of the most spectacular events worldwide. All told, the tiny insects fly upwards of 2000 miles round trip each spring, stopping four times to breed and lay their eggs. They are the only butterfly species to make such a long, two-way migration.

monarch migration

Over the past 25 years, however, there’s been a sharp decline in monarch populations. Part of this is due to a loss of habitat at the butterflies’ overwintering site in Mexico. Activities such as logging, agriculture and urbanization have all taken their toll on the central highland forests that play host to the insects six months out of every year.

But by far the most significant factor driving the decline is the dwindling supply of a plant called milkweed. The native wildflower is the only plant that monarch caterpillars will eat. And without it, the butterflies cannot complete their life cycle, sustain their migration and ultimately, perpetuate their species.

monarch feeding on milkweed

MONARCH BUTTERFLY GARDENS NEED MILKWEED 

According to the North American Monarch Conservation Plan, we need 1.8 billion milkweed stems to replace those that have been lost to agriculture and urbanization. And to sustain the annual migration, these contributions need to come from all land sectors. This includes farms, roadsides, schools, zoos and rights of way. And it also includes suburban and urban gardens located along the butterflies’ migratory corridor.

Happily, an initiative called the Monarch Waystation Program is starting to make a crucial difference. Established in 2005, it engages citizens in conservation by providing instructional materials on how to build and maintain your own monarch habitat. The guidelines are simple: Plant two or more milkweed varieties for the caterpillars to feed on along with some nectar sources for the adults, and you become part of a national registry.

To date, over 6000 Monarch Waystations in 46 states have become part of the effort. 

WHAT MONARCHS LIKE

As it happened, the Waystation Program Registry provided the perfect jumping off point for Potter’s research into monarch butterfly gardens. A quick Google Earth search by his team revealed hundreds of habitats scattered along the butterflies’ northward route. What’s more, they represented every kind of landscape.

As Potter put it, ‘Some were non-structured, others ‘wild’, and still others were surrounded by hardscape or located in open rural areas.’ Below are some aerial shots of a few of them. (Photo courtesy Dr. Daniel Potter.)

What Potter and his team wondered was this – with all of this diversity, were there certain habitats that the butterflies found more attractive than others? To find the answer, the group decided to survey 22 citizen-planted Waystations. Below are some key outcomes from their investigation. 

1. MONARCHS LIKE STRUCTURE

Like most species, monarchs use visual cues to zero in on what they’re looking for. And in the butterflies’ case, these ‘search images’ are made up exclusively of milkweed. But as the Registry revealed, not all Waystations are the same. Did monarchs favor certain monarch butterfly gardens over others?

Monarchs from ‘search images’ for milkweed

To find out, the researchers counted larvae and caterpillars for a year in their target Waystations to see if the type of habitat made any measurable difference.

And they discovered that yes, the butterflies exhibited a strong preference. A structured garden, with milkweed surrounded by mulch, attracted three to five times more monarchs.

The takeaway? If you want more monarchs, make it easy for them to find the milkweed to lay their eggs on. Plant it apart from other plants. Even better, surround it with a mulch circle. But make sure to provide other nectar producing plants nearby for the returning adult butterflies to feed on.

2. MONARCHS PREFER A NORTH-SOUTH ACCESS

Interestingly, the researchers found that gardens with unimpeded north-south access recruited more monarchs. This makes sense since it coincides with the butterflies’ migratory route.

Monarchs prefer gardens with a north-south access

3. THE TALLER THE BETTER

While all milkweed species are suitable for food, not all are equally favored by monarchs. To find out why, the group compared 8 varieties of milkweed all grown in Kentucky and native to the area. They evaluated them as to their suitability for egg-laying as well as their usability as food for monarch caterpillars. And there was a clear preference.

Where they had a choice, monarchs preferred the taller varieties, Swamp, Common and Showy over the smaller varieties like Butterfly weed

The takeaway? If you want to attract more egg-laying monarchs to your monarch butterfly garden, plant the tall, broadleaf milkweed varieties.

4. MILKWEED CULTIVARS ARE EQUALLY TASTY

But what about all of the new milkweed varieties, you might ask? As it has grown in popularity (mainly due to monarchs), milkweed is now available in many cultivars boasting unusual colors and sizes.

Asclepias Gay Butterflies Mix/White Flower Farm

Not to worry. Potter and his students discovered that monarchs find these cultivars just as attractive as the straight species. But again, go with the bigger varieties if you want more monarchs.

5. DON’T BECOME AN ECOLOGICAL TRAP

Finally, there’s the case of tropical milkweed, a non-native plant that has exploded in popularity over the past decade. Both gardeners and monarchs love it. But buyer beware. Tropical milkweed is not ‘bad’, per se, but when planted in warm areas of the U.S. it encourages monarchs to stick around longer. It even enables them to winter-breed.

Research shows, however, that monarchs breeding on tropical milkweed throughout the winter (rather than returning to Mexico) have higher levels of protozoan infection compared to monarchs in the normal migratory cycles. It turns out that migration is key to outrunning these pathogens.

The takeaway? Stick to the tried and true native milkweed species and help the insects keep to their schedule.

Why Lily of the Valley is the Official May Day Flower

Years ago, I was living in Paris when there was a knock on the door followed by the sound of running footsteps. Opening the door, I discovered a basket of tiny white flowers on my doorstep. Little did I know, I had just received a gift of lilies of the valley, a flower exchanged each year in France on the first of May.

ROYAL ROOTS

In France, lily of the valley (or muguet in French) has been given as a gift for centuries. Legend has it that the custom began on May 1, 1561 when King Charles IX received a sprig of the tiny flower as a token of good luck.

The King liked the idea so much that he decided to start a tradition. From that day forward on the first of May, he presented a bouquet of lilies of the valley to each of the ladies of his court. And thus began the Fête du Muguet, otherwise known as May Day in France. 

Portrait of King Charles IX

MAY’S MOST CELEBRATED FLOWER

Over the centuries, lily of the valley has since become one of May’s most celebrated flowers. And for good reason – it typically blossoms in April and stays in bloom for most of May. Averaging just around six inches, each plant is composed of a pair of leaves and a single stalk of bell-shaped flowers with a sweet, jasmine-like scent.

Still, for what it lacks in size, lily of the valley rapidly makes up for in numbers. When given ample shade, plants will form low, thick masses of bright green color, making them the perfect complement to other shade-loving perennials.  

THE STORY OF LILY OF THE VALLEY AND THE NIGHTINGALE

Legend tells that the very first lily of the valley was in love with a nightingale. Every night, the nightingale would come to her garden to sing. However, the lily of the valley was shy and hid herself from the bird. So eventually he grew lonely and flew away.

Alone in the garden, the lily of the valley waited in vain for the nightingale to return. Eventually, she grew so sad that she stopped blooming. She started flowering again only after the nightingale reappeared (in May) and her happiness was restored.

SYMBOL OF LOVE

In early 20th century France, men often gave bouquets of lilies of the valley as tokens of affection. They presented their gifts, in accordance with tradition, on the first of May. In their absence, they sent romantic postcards featuring pictures of the flower accompanied by wishes of good luck. French people still practice the card-sending ritual today.

A NATIONAL HOLIDAY IN FRANCE

In modern-day France, the first of May coincides with National Labor Day. As a result, the Fête du Muguet is a public holiday. In the days leading up to the event, lilies of the valley are sold from roadside stands that pop up all over the country. And while it’s normally forbidden to sell flowers on public streets, the ban is lifted on May 1 in honor of this long-standing tradition.

HOW TO GROW LILY OF THE VALLEY

Easy-to-grow lilies of the valley are indigenous to temperate climates. Spreading by tiny rhizomes underground, they naturalize easily and can quickly become invasive. Unless you’re up for continually digging them out to control them, it’s best to plant the flowers in their native woodland or in a contained area in the yard.

And like most shade-loving plants, lilies of the valley prefer moist, well-drained loamy soil. Never plant them in full sun. If you do, their bright green leaves will lose their color and turn ugly shades of brown. 

DON’T EAT THEM

Finally, you may be surprised to learn that all parts of the lily of the valley are toxic if eaten. So when handling the flowers, it’s best to wear gloves to prevent any residue from being transmitted to food. Symptoms of lily of the valley poisoning include stomachache and blurred vision.

Why Star Magnolia Deserves A Spot In Your Garden

When it comes to stunning, early-flowering trees, it’s hard to beat the star magnolia. Every spring, it bursts onto the landscape in a flash of bright white. For what it lacks in size, it more than makes up for in stature. I love how the blossoms hang like fallen stars from the tree’s smooth, bare branches.

THE SMALL GARDEN’S MAGNOLIA

Now, even small gardens can have a magnolia! What’s more, a star magnolia is slow-growing, so it won’t overwhelm your landscape. Topping out at a manageable 10 to 15 feet, it makes an excellent specimen tree while also providing a great backdrop to any mixed shrub border. 

And who can resist those early-spring blossoms? Typically flowering in early March, star magnolia is heavy with blooms when most other trees are scarcely beginning to bud. Moreover, the flowers are long-lasting and fragrant; each composed of more than a dozen ribbon-like petals, with some varieties boasting as many as 30.

White flowers not your thing? There are also a number of pink varieties. All are magnets for pollinators, which gives your other plants an early start on the season.

FOR STAR MAGNOLIAS, THE SHOW NEVER STOPS

But, for those who think star magnolias are all about spring, think again. The little trees offer fall and winter interest as well. In autumn, the foliage turns yellow and then bronze, beautifully complementing other fall colors.

And in winter, the tree’s shiny brown branches contrast beautifully with a gray trunk that turns silver with age. By late winter, masses of fat, fuzzy buds appear. 

TOP STAR MAGNOLIA VARIETIES TO TRY

Ready to give star magnolia a try? Below are some the most popular varieties that offer reliable, low-maintenance early-spring color. Deciduous magnolias are best planted when dormant, typically in late fall.

‘Centennial’ produces fragrant, waterlily-shaped blossoms in early to mid spring. The large white flowers often have a pink tinge at the base of the petals. 

Magnolia stellata ‘Centennial’

‘Jane Platt’ produces double, scented, pale pink flowers with long, narrow petals in early to mid spring.

Magnolia stellata ‘Jane Platt’

‘Royal Star’ has pale pink buds that open in early spring to pure white flowers. In particular, this cultivar is known for its almost 5-inch (12 cm) wide flowers with up to 30 petals. ‘Royal Star’ blooms later than the species. 

Magnolia stellata ‘Royal Star’

‘Rosea’ is a pink-flowered variety. It has a rounded shape and dense bushy habit. This cultivar flowers a month later than the species, or in late April. 

Magnolia stellata ‘Rosea’

HOW AND WHERE TO PLANT

Star magnolia flowers are vulnerable to damage by late spring frosts, so it’s best to plant the trees in a sheltered spot. While they’ll do fine in full sun, they’ll perform best in morning sun with filtered shade in the afternoon. Generally, the more exposed the location, the earlier the flowers open. Like most plants, star magnolias prefer moist, well-drained soil. 

Magnolia stellata really shines when viewed against a dark background. Site it in front of a stand of deep green arborvitae, a yew hedge or even a dark brick house and watch its flowers ‘pop.’  Daffodils with cream or white petals and yellow cups make excellent early-spring companions. Check out Narcissus ‘Sovereign’, Golden Echo’ or the orange-cupped ‘Barrett Browning’ for a dramatic effect.

 

Plant Trends 2021: What’s New for Spring

Even in the world of gardening, it’s important to stay ahead of the curve. And to do so, one need look no further than Kathy Jentz. As editor and publisher of Washington Gardener Magazine, her depth of plant knowledge is incredible. Recently I attended her talk on the biggest plant trends for 2021 during which she highlighted some key things to look out for this spring. 

SIMPLIFICATION IS KEY

These days, the overriding theme is simplification. Unless you’re up for the task, who wants to buy a plant that needs weekly spraying or constant pruning to keep it in bounds? Jentz says consumers want their plants to bloom longer, have greater disease resistance and be able to stand up to drought and other factors due to climate change. And growers are rising to the challenge.

Indeed, growers are answering the call by engaging in greater hybridization to propagate desirable characteristics such as color, size and vigor. Here are four plant trends Jentz says are rocking today’s industry. 

TINY PLANT TREND

Plants are scaling down – think dwarf evergreens, smaller shrubs, and more compact and manageable perennial species. Not only are these new hybrids better suited for smaller gardens, but they also require less maintenance while flowering longer. (And for growers, they look better on the shelves.) Teeny tiny houseplants like terrariums plants and tiny succulents are also gaining in popularity.

DAY LENGTH NEUTRAL PLANTS

Day length neutral (D/L) refers to plants that flower independent of day length. In other words, unlike short-day plants that flower in spring and long-day plants that flower in summer, these plants will flower all season long. That means that if you want to grow sunflowers in early spring or late fall when days are shorter, all you need to do is choose a day length neutral variety. 

plant trends D/L neutral sunflowers

ENVIRONMENTAL SUITABILITY

These days, you can’t be too sure of the environment. So growers are responding by introducing plants that exhibit higher degrees of drought tolerance and disease resistance. Some varieties have even been bred to stand up to wind, wet weather and road salt, providing more options for the home gardener.

NEW BRANDING OF FRUITS AND VEGGIES

For those of us who dislike having to cut up an entire melon to consume only a few pieces, say hello to personal snack-able fruits and veggies. Helo Clementines and Hello Melon are two great examples of this 2021 plant trend. Personal-sized fruits and veggies make it easier for consumers to eat healthy food with less wastage. Now you really can have your melon and eat it too.
