Is your flower garden a study in pinks, oranges, and yellows? Wouldn’t you like to add a little drama? If your favorite color is purple, you’re in luck because there are a lot of choices for flowers, foliage, and berries in a wide variety of purple hues. You can create different looks, depending on the shade of purple you use and the other plants you combine it with. Purple isn’t always one of those “Wow!” colors, but it acts as a great contrast to orange and yellow, which command more attention. It adds a subtle sophistication to the showier colors, and when planted in a combo, that contrast actually makes each color stand out more.
‘Red Rubin’ basil (Ocimum basilicum purpurascens)
This tender perennial is as attractive as it is useful. A staple in the herb garden, its fragrant purple leaves work well in containers and borders. Always pinch off flowers as soon as you see them starting to bloom. Doing so encourages the plant to keep producing leaves, making them bushier. It tastes as good as it smells! For culinary drama, combines it with yellow tomatoes. Or try making purple basil vinegar or jelly. Cold hardy: USDA zones 10 to 11.
‘Concord Grape’ spiderwort (Tradescantia hybrid)
The dark green grasslike clumps of ‘Concord Grape’ spiderwort are one of the first things
to emerge in spring. Then a big show of flowers starts a few weeks later. Hot weather and lack of rain are hard on spiderwort. Cut plants back by two-thirds when the heat takes its toll and keep them well watered during dry spells. Dig the clump in spring and cut into smaller sections, then replant them. They recover quickly, and will probably even bloom the first year. Larger leaf plants contrast well with spiderwort’s grassy foliage. Try planting with Japanese painted fern (Athyrium niponicum pictum) or Lungwort (Pulmonaria ‘Sissinghurst White’). Cold hardy: USDA zones 4 to 9.
KICKIN ‘Lavender’ aster (Aster hydrid)
In autumn, reds and oranges take over the landscape. Sometimes you want a little purple to add to that fall blend. Asters are perfect for that, and their late-summer flower show is a welcome sight. It starts when a lot of others are fading out. KICKIN ‘Lavender’ is on the small side compared to standard asters, so it can be planted closer to the front of the border or in containers. Blooming asters show up in garden centers in late summer, but they will survive better in the north if planted in spring so they can get established. Cold hardy: USDA zones 5 to 9.
