Heuchera is an attractive perennial belonging to a genus of more than seventy species native to the US Rocky Mountains. Plants form low rosette mounds of lobed leaves that are often marbled with gorgeous coloring. Their 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 and veining. 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. The plants 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 or fish emulsion once as summer approaches and then again in late summer. Remove faded flower heads to keep the plants looking tidy.

Heuchera info:

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.
