Duke Class of 2020

Heuchera, commonly known as coral bells, has grown increasingly popular with gardeners for its adaptability and because butterflies love it. We will have five varieties at our Spring Plant Sale this  Saturday (event details below), and Duke Gardens members can get first dibs at Friday’s members-only preview sale. Here are two varieties that gardeners are sure to love.

Heuchera ‘Rose Quartz’ is a gorgeous metallic-looking plant best known for the holographic effect of its impressive foliage. The leaf color starts out as a light dusty rose before transitioning to a light pewter color. In early summer, pink buds give way to cream flowers, making this the perfect summer-blooming perennial to add to any garden.

Heuchera ‘Rose Quartz’ attracts butterflies, hummingbirds and bees, and it’s deer resistant. This is a fairly easy-to-grow plant that demonstrates more tolerance of heat and humidity than many other species. Native to the Southeast, Heuchera ‘Rose Quartz’ thrives and produces the most vibrant colors in partial shade environments, although it will also do fine in full sun with constant moisture. In the spring, any damaged leaves should be removed for optimal regrowth. Good drainage is crucial to this plant, and when it is given consistent care, it may act as an evergreen.

The colorful spread of the ‘Rose Quartz’ foliage can reach 12 inches, making it a focal point for borders and containers. Planting time is from late winter to late spring or late summer to early fall. Late summer will provide the best display of blooms in the spring. Consider using this plant to provide a mysterious shimmer to your garden border.

Heuchera ‘Citronelle’ was created accidentally by gardeners attempting to produce its close relative Heuchera ‘Caramel’. It is considered a Heuchera villosa hybrid and is native to the Southeast. Featuring vibrant citron leaves with silver undersides and cream-colored flowers, Heuchera ‘Citronelle’ is a colorful container plant perfect for gardeners looking to spice up their arrangements.

Like the Heuchera ‘Rose Quartz’, ‘Citronelle’ attracts butterflies, hummingbirds and bees, and it is deer resistant. Unlike its heat-resistant cousin, however, ‘Citronelle’ is more sensitive to sun and will experience color fading if placed in full sun. This species requires weekly watering, though more frequent watering may be necessary in extreme heat. Good drainage is essential, and the only pruning required is removing any winter-damaged leaves during the spring.

This bright yellow plant is well-paired with hostas (see our hosta preview here), and it can be used as an edge or container plant. It is easy to grow and complements most perennial arrangements. The leaves are low and form in clumps, making it the perfect plant for perennial borders. Heuchera ‘Citronelle’ is a cheery plant to brighten any summertime garden.
