I have heavy clay soil in most of my yard. One area has some sand and another has some peat mixed in and this plant does great in both locations. I divided my two plants last fall after 3 yrs of growing and got at least 6 or 7 new plants. Once they start blooming, they bloom most of the season and the hummers love them. In my garden they don't like prolonged wet feet so I try to keep them a bit on the dry side. They are planted in a bed with salvias , agastaches and penstemons so they are in good company.

This is one of the most fickle of all heucheras - also used in hybrids and varieties too often. Many hard to grow varieties of heucheras can be blamed on this as the parent plant. It and its hybrids are mainly grown for flowers even thought there may be either variegation or once in a while maroon leaf or golden leaf variety. Prefers sun to light shade so any hybrids made with this as the parent plant also strongly tend to be sun to light shade. I have planted at least six to seven plants - variety I can't remember but definitely releate to this species and of all of those, only one have survived and it have taken 3- 5 hours of sun, mostly noon. Early morning and afternoon it is shady.

This is a hardy - it did very well even though there were two weeks of freezing temperatures in Seattle - as in 26F -in a container.

I love this plant! It's flower stalks are so long and thin that the little pink blooms appear to float in the air. And as for clay soil, they thrive in my clay soil. I live in northern Alabama and my soil is like a big red clay pot. My heucheras grow so huge I have to keep dividing them.

Heucheras provide a long flowering season. They make great bouquets, and are equally effective in the garden.

Dividing the stems every 3-4 years prolongs the life of the plant.

I have had rotten luck with heucheras in my garden. Just finished researching possible reasons and found out the heucheras do not like clay soil. Guess what I have? Yep, red clay soil with very little organic matter unless amended. I think if I try these beautiful plants in raised flower beds so that the roots stay above and out of the red clay base soil that they'll do just fine.

Plant has reddish-green leaves (some varieties have variegated foliage.) In early summer clusters of nodding pink, coral, white or red bell-shaped flowers atop wiry stems appear; attractive to bees and hummingbirds.

Plant in well-drained moist soil, provide afternoon shade in hottest climates. Seed heads are brown and unimportant.
