About: Coral bells (Heuchera) is also known as alumroot. These mounding perennial
plants are hardy to zone 3 and they’re often listed as evergreen in many climates.
They can be found in several foliage colors—such as bronze, purple, red, chartreus,
pink, green, and multiple variegated variegated. The spikes of tall, bell-shaped
blooms is where the coral bells flowers get their name and are just as impressive as
the foliage color, blooming in late spring to early summer. There are also late-
blooming types available. The flower color varies too, with colors ranging from white
and pink to light coral and deep red.
Care: Coral bells don't need much maintenance. The bloom stalk can be
cut back after flowering to allow the plant put its energy into growing
more leaves. If the leaves get a bit ragged looking, especially after
winter, cut them back and new growth should fill in quickly. Deadhead
the faded flowers regularly as this will help ensure repeated blooming
all summer and into fall.
When to Plant: Coral bells are best planted in late fall or early spring and will grow at a
moderate pace. This makes them a great option for woodlands, rock gardens, containers,
borders, and ground covers. They are short-lived perennials; unless divided regularly, they will
die out in a few years.
Soil Type: Most Heuchera like a humus-rich soil that is moist but well-drained. To provide a healthy
environment for Heuchera to grow in garden beds or containers, good soil drainage is essential. In
their native habitat Heuchera are found growing on slopes and even cliffs. They like a soil that is rich in
organic matter but soft and porous. This means it might be necessary to amend heavy clay soils,
which tend to hold a lot of water (especially during winter), with compost.
Water Tolerance: Coral bells prefer consistently moist soil. Like most plants, they do best when
receiving an inch of water per week combined from rainfall and hand watering. They may need
more water if they are in a sunny location where the soil may become dried out.
Bloom Time: Coral bells bloom in early to mid-summer, depending on the species and climate.
Companion Plants: For shady locations, combine with other woodland plants such as astilbe,
bleeding heart, ferns, hellebores, hosta, Japanese forest grass and lamium.
