This attractive perennials belongs to a
genus of more than seventy species and is native to the Rocky Mountains. Heucheras
form low rosette mounds of lobed leaves that are often marbled. The low growing habit make
them perfect for edging or for tucking between stones in a rock garden. The foliage
is evergreen and many new cultivars have very unique variations of color. The flower
stems which stand above the mounds of foliage are between 16 and 24 inches tall depending
upon the variety. Heucheras will grow more vigorously and maintain stronger colors
if planted in an area that is protected from hot afternoon sun. Plants are tolerant
of a wide range of soils but prefer a rich moist location that drains well - a soggy soil
will cause the crown to rot. Heucheras are also salt tolerant which make them
useful in the north planted along walkways which are frequently salted. Feed plants
in early spring just as new growth begins to appear with a top dressing of composted
manure and bone meal. Liquid feed with seaweed extract once as summer approaches
and then again in late summer. Remove faded flower heads to keep the plants looking
tidy.
Heuchera ( AKA coral bells )
Zones: 3-9
Propagation: division
Problems: if growing heuchera in containers or pots make sure to let the
soil dry between waterings - constant dampness will cause crown rot.
Notes: although this perennial is classified as an evergreen we
consider it to be more semi-evergreen in colder climates. Heucheras can heave in
colder climates - an extra layer of mulch or shredded leaves applied in late fall can help
remedy this problem.
