HEUCHERA & HEUCHERELLA
Heucheras are a summer-flowering perennial forming
large dense mats of attractive foliage from which grow wiry stems holding numerous, tiny bell shaped flowers.
Hardy to zone 4 unless otherwise stated. Heucheras are
invaluable "evergreen" foliage plants for the garden where they can be used in the herbaceous border, in containers or even in hanging baskets.
Depending on the cultivar, the size of the mound of foliage varies from 15-60 cm, while the stems of flowers are 15-90 cm tall. Heucheras require a moist but well drained soil in sun or partial shade. Purple foliage cultivars with marbled or marked leaves keep their
contrast best in full sun.
Heucheras are good bee and hummingbird plants, plus deer resistant. As with all deer resistant plants, resistance may depend on local herds. If you want
DAZZLING colourful foliage without slug damage, try heucheras. An all-heuchera bed is incredible for all year colour.
Heucherellas are produced by crossing Heucheras and Tiarellas, and generally have Tiarella-type flowers with
Homeowner Growing & Maintenance Tips:
Heucheras are easy perennials to grow and fit nicely in the front of any border, rock garden, or container. They grow most vigorously and have the stongest colors when grown in partial shade (preferably afternoon shade). They can also be grown in full shade but their growth rate will be very slow. Some varieties can withstand full sun in northern climates if they have consistant 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 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.
