MaintenanceDepending on the species some will produce a prodigious amount of flower scapes and these should be deadheaded. I prefer to gently remove the dead leaves in the spring. Gently is the key word since some Heuchera do not produce stout clumps and pieces are easily broken off. Heuchera tend to frost heave, a mulch will help prevent this. Gently pushing the plants back into the ground in the spring is a good practice. Rejuvenation by division may be need as the plants get older and form thick heavy stems at the base of the plant.

Cultivar OriginTerra Nova Nursery, 2000
Author's NotesI have grown and observed many different Heuchera over the years. I ran a nursery when "Palace Purple" was the most popular. Now there are so many cultivars it's mind boggling. In my opinion the best place to grow them is in an area that gets some full sun but the plant isn't baked, like an east exposure. In the full sun they will need some additional moisture
