Top Red, White and Blue Flowers For The Summer Garden

For many Americans, Fourth of July is synonymous with fireworks. But for gardeners, the pyrotechnics start early. That’s because by mid June, spring pastels are already giving way to dazzling color as red, white and blue flowers begin lighting up the summer garden.

RED FLOWERS EXCITE

On the color spectrum, red is the most attention-grabbing of colors. In China, it symbolizes prosperity and good luck, while on Wall Street ‘in the red’ means you’re losing money. And on the American flag, the red stripes represent ‘hardiness and valor.’

In the summer garden, red flowers make a dazzling display, especially when framed by red’s complementary color, green. Looking for drama? Try grouping red flowers in front of an evergreen hedge and watch the fireworks begin!

 Or, combine them with other hot colors for an eye-catching composition. 

Too many red flowers? You can cool things down by pairing them with silver.

And just like the stripes on the flag, white flowers offer a crisp contrast to all shades of red.

WHITE FLOWERS BRIGHTEN

The purest of all colors in terms of composition, white is considered by most cultures to represent goodness and light. It can also indicate cleanliness and perfection. On the American flag, the white stripes signify purity and innocence.

In the summer garden, white flowers add an unblemished quality to the mix. Since white reflects light, white flowers instantly brighten key areas of the garden. They also help highlight other colors.

Some gardeners even go all out and create an all-white garden. (The great thing about white flowers, by the way, is that they look especially good at night.)

BLUE FLOWERS CALM

Located at the other end of the color spectrum from red, blue is considered the hardest color to see. For this reason, it is known as a cool color. On the American flag, blue is the color of the Chief. It signifies vigilance, perseverance and justice.

The thing about blue is that it appears to recede (notice how the blue section of the flag seems less intense than the red.) Because of this quality, blue flowers can add depth and volume to a garden composition. The only problem with blue flowers is that there aren’t many that are truly blue. Most are tinged with lavender or purple. However, color can be subjective, so people have different opinions on what’s blue.

Here are the truest blue flowers I’ve found to date for the summer garden:

Blue-Flowering Shrubs

Hydrangea macrophylla ‘Nikko Blue’

‘Bluebird’ lacecap hydrangea

Caryopteris ‘Longwood Blue’

Blue-Flowering Perennials

Blue coleus, also know as bush coleus

Gentian Sage, Salvia patens 

Lewis flax, Linum lewisii

Blue Daisy

Muscari aucheri ‘Blue Magic’

Mostly blue with lavender tinge

Hidcote Blue English Lavender

Veronica spicata ‘Royal Candles’

Russian sage, Perovskia

Catmint, Nepeta

Wishing you all a very Happy Fourth of July!
