Having A Ball With Alliums (Ornamental Onions)

Allium giganteum, also known as Giant Onion 

They look like they’ve jumped out of a Dr. Zeus book — giant purple balls stuck like lollipops on long flexible stems. Alliums can be a bit startling the first time you encounter them. But there’s so much to love about these drought tolerant plants, like long bloom period and resistance to most pests and diseases. And, their whimsical appeal is a sure-fire way to liven up your garden. Continue reading

Mount Sharon: There’s Gold In The Hills Of Orange, Virginia

The Rose Garden at Virginia’s Mount Sharon

High on a hilltop in beautiful Orange, Virginia, there’s a garden property that will leave you speechless. Known as Mount Sharon, it occupies the second highest point in the county. The magnificent estate, which includes a large, redbrick house in the Georgian Revival style, is seldom open to the public. So recently, when my garden club received an invitation to tour the gardens, I could hardly wait to go. Continue reading

Nine Things To Ask Yourself Before Designing A Garden

One of the many things I love about being a garden designer is getting to know my clients’ story. By this I mean what role gardens have played in their lives, what plants, structures, and ornaments evoke certain memories, and what kind of garden makes them feel relaxed and most happy.

Buenos Aires’ El Rosedal: Taking Time To Smell The Roses

‘A collection of old roses gives a great and increasing pleasure.’

–Vita Sackville-West

There are rose gardens and then there are rose gardens. It’s not every day you come across a rose garden covering nearly 10 acres. But Buenos Aires’ El Rosedal, commonly known as the Jardin de las Rosas (Rose Garden), is just such a place. And the magnificent space is immaculately maintained and surprisingly, free to the public.

How To Create An All White Garden

All-white garden by Here By Design

It’s true that we all see colors differently, but it’s rare to find someone who can’t see white. That’s because white, like sunlight, is composed of all the colors of the visible spectrum. In the garden, white plants reflect light, instantly brightening the look of shady spots. And an all-white garden is a symphony of light, where distinct parts of flowers and foliage join together in a timed succession of harmonious arrangements.

White is a great tool for designers. It attracts the eye and focuses attention on key areas of the garden. In a dark corner, it appears to move forward, while when juxtaposed with colorful plants, it acts as a beacon, calling attention to itself. The real beauty of white, though, is most apparent at night. That’s when white flowers take on an unearthly glow, shimmering like ghosts in the moonlight.

And, many of these nighttime blooms have intense, sweet smells that attract their own group of night pollinators, bringing an entirely new perspective to the garden.

6 TIPS FOR DESIGNING AN ALL WHITE GARDEN

Since by definition a white garden is lacking in color, it naturally relies on shape, size and texture of the elements that make up its structure. Think of a black and white photograph: what makes it interesting?

The appeal of black and white photography lies in its ability to capture details without the distraction of color.

How does it do this? By playing up contrasts between dark and light, repeating lines and forms and demonstrating a strong interplay between foreground and background. These are the same elements that make the white garden interesting.

1. Choose a dark backdrop

To show white-blooming plants off to their best advantage, it helps to place them against a dark backdrop. Consider positioning your white garden in front of a dark green hedge formed of dense shrubs like boxwood, holly or yew or plant your garden in front of a deep red brick wall. Dark-toned doors, black gates, and houses painted in dark brown, green or gray all make stunning backdrops for white flowers.

The back of the border is the perfect place for medium-sized white-flowering shrubs such as Hydrangea arborescens ‘Annabelle’ and Philadelphus coronarius (Mock Orange.) Their soft mounding shapes give structure to the garden and make a great transition from a strong, dark backdrop to more delicate perennials.

2. Vary foliage

Focusing on leaves is a key way to add interest to a monochromatic garden. Not all leaves are created equal. Foliage can vary from light to dark green, be spiny or fern-like and exhibit a range of finishes anywhere from a dull matte to a dark glossy shine. Some greens are gray while others tend more towards blues or yellows. I always select a variety of white-flowering plants with different colored green foliage to add interest to a white garden.

And, don’t overlook variegated foliage, which can perform the same function as white flowers. In the white garden, leaves with cream or white margins keep working long after other plants’ flowers have faded, brightening the garden all season long.

3. Vary shapes and sizes

Varying shapes and sizes of plants provides stark contrasts in the one-color garden. Mixing tall spires with rounded shapes, upright plants with low creeping ones and mounded forms with loose and rambling specimens enables white-flowering plants to be appreciated from many different perspectives.

4. Repeat forms

Within the flower world, there are many species that resemble each other. To help unify an all-white garden, I often repeat forms by selecting plants that have flowers that look similar but are not necessarily of the same species.

For instance, peonies look a lot like roses and have a similar shape to the blooms of Hydrangea macrophylla ‘Annabelle’. Tiny Boltonia asteroides, looks like a miniature Shasta daisy, Leucanthemum. And within the iris family, the tall, elegant flowers of reblooming Iris ‘Immortality’ echo the shape of the smaller-sized Japanese iris ‘White Swirl’ to dramatic effect.

5. Add silvery highlights

Silvery plants act as transitional plants, helping to lead the eye around the space while adding structure to an all-white garden. I like to use groups of the velvety-soft greenish-silver ‘Big Ears’ lamb’s ear, Stachys byzantina, at the front of the border. For added drama, I’ll often plant the woody-based perennial Artemisia ‘Powis Castle’ in the mid section of the bed where its silvery, fern-like foliage provides a soft contrast to the other green-leafed perennials.

6. Deadhead regularly and infill with annuals

White flowers, when they fade, can turn into a less attractive form of brown. I deadhead my white flowers regularly to keep them looking their best. Once groups of perennials have stopped flowering, I cut them to the ground (unless their foliage remains attractive) and fill in with white-flowering annuals like snapdragons, sweet alyssum, nicotiana alata, verbena, angelonia and white pompom dahlias. Click here for my post on how to deadhead and maximize blooms.
