Plant Profile: Heuchera (Coral Bells)



Looking for a great plant for the shade.  Take a look at the Heucheras. Heucheras are easy perennials to grow and can be easily placed in the front of any border, rock garden, or container. They grow most vigorously and have the strongest colors when grown in partial shade (especially afternoon shade). They can also be grown in full shade but their growth will be very slow. Some varieties can withstand full sun in northern climates if they have constant moisture, but their colors tend to fade with the intensity of the sun. The soil should be amended with organic matter prior to planting. It should also have good drainage and a neutral pH. Heucheras are evergreen in areas with mild winters. If properly sited out of the way of winter winds and with reliable snow cover, gardeners in northern regions may also find their heucheras acting as evergreens. If the plant looks tattered by early spring, shear off any damaged leaves to make room for the vibrant new foliage which will fill in quickly. Heucheras can be grown under black walnut trees because they are resistant to the toxin, Juglone, which the black walnut trees emit from their roots. Heucheras are also salt tolerant. They are useful in the north along pathways which are salted in winter or for people gardening in coastal regions. Occasionally in northern regions, heucheras have a tendancy to heave out of the ground because of the freeze/thaw cycle. To combat heaving, add an extra layer of compost around the plant's roots in the fall. In the spring, if the plants have heaved at all, the new roots will grow into the fresh new layer of compost.

Several of our newer varieties include:

Citro1.jpg
  Heuchera 'Citronelle' is a robust hybrid with citron yellow leaves and silver undersides. When planted in heavier shade, the leaves will be more chartreuse. Since the leaves are so light in color, this variety appreciates more shade than some of the other heuchara varieties.

This plant is a Heuchera villosa hybrid. The villosa species is a large, late blooming type that exhibits an increased tolerance of high heat and humidity over other species. Most produce cream flowers in midsummer, though they are grown more for their fantastic foliage.

  Heuchera 'Marmalade' has foliage that will range in color from umber to deep sienna. The rich, shiny, undulating leaves are of heavy substance, helping them to stand up to inclement weather. Lots of reddish-brown flowers appear on 16 inch scapes from late spring to early summer. This selection grows best in partial to full sun.
