In the Garden: Heucheras add color in shady places

When designing ornamental garden beds, we often tend to think in terms of colorful flowers. We don’t necessarily have to rely on flowers alone to add pizzazz to our landscapes. Two great alternatives are heucheras and heucherellas, both prized for their foliage.

Heucheras, commonly known as coral bells, come in a wide range of colors. Heucherellas are a cross between a heuchera and tiarella, which many gardeners know as foamflower.

Martha Kenney is absolutely smitten with both of these plants. A Master Gardener since 2002, her main focus is on perennial gardening.

“I’ve had an interest in heucheras for 37 years,” she said. “There were lots of them growing at the house we were renting so our landlady let me bring them to this house.”

After that, a neighbor gave Kenney a Palace Purple hybrid. This cultivar was the beginning of a wave of heuchera hybridization in the plant industry.

“I thought Palace Purple was so cool,” she said. “Amber Waves was the next one that caught my attention, and that was it: I was hooked.”

Soon, Kenney and a fellow Master Gardener had a friendly competition going as they tried to keep up with the newest varieties introduced each year.

There are nearly 50 species native to North America. As members of the saxifrage family, they are also referred to as alum root for their medicinal properties. Historians have noted that heucheras can be seen in botanical prints going back to the 1600s.

For years, the common coral bells (H. sanguinea) were the only ones available in nurseries.

“The flowers were either red or pink, they had green leaves, and weren’t all that interesting except for some veining in the leaves,” Kenney said. “But they were not like the new cultivars.”

She feels heucheras and heucherellas have a lot going for them.

“The variety and leaf color is just unbelievable. They go from oranges and peaches, to deep purple to black, to everything in between. The flowers attract bees and hummingbirds, too.”

Both are shade plants that blend well with other shade-lovers such as hostas, brunneras, ligularias, ferns and cimicifugas. Having evergreen foliage, most heucheras and heucherellas, are very hardy and are deer-resistant. Some are even drought-tolerant.

“These plants need shade although some are more tolerant of sun than others,” Kenney said. “Water them regularly. Deadhead the spent flowers and cut off the old leaves in the spring. Otherwise, they really don’t need much care.”

While they are tough plants, she’s found that root weevils will occasionally nibble on the margins of the leaves but hasn’t come up with a successful method to combat them.

“I just figure they’re not killing the plant,” Kenney said. “Usually they are the worst in the fall when the plants are getting ready to go dormant anyway. If they were killing the plants, that would be a different story!”

Some of her favorite heuchera cultivars include Southern Comfort with its huge copper leaves, splashy Mardi Gras, Sweet Tea, Mystic Angel, Peach Flambe (“it just glows when the sun shines behind the leaves”), Amber Waves, Lime Rickey and Midnight Rose. Two of her most prized heucherellas are Brass Lanterns and Running Tapestry.

“Heucheras and heucherellas have such variety in size, shape, color and go well with a lot of other shade plants,” she said. “I honestly think they should be a staple in every shade garden.”
