Description

This large leaf native Heuchera from which many hybrids have been derived will reach about 1' tall in bloom and has deep green leaves with white flowers with a touch of pink.

Maintenance Tips

Heuchera maxima is a small, clumping perennial that is native to the Channel Islands. It only grows to about 12” tall and has wide, marbled leaves that give it a unique look. The pink flowers emerge another 12” above the foliage in the spring. This native evolved in shady areas under trees and in canyons, so it is best to plant it in areas with dappled sun. If it is planted along the coast, it can usually thrive in full sun. There is very little maintenance involved with this plant. The older leaves tend to stay on the plant and collect under the younger foliage. These can be cleaned out occasionally to allow some sunlight to the inside of the plant and to improve air circulation. The flower stalks, once they are spent, can give the plant an unkempt look, so deadheading them will keep the plant looking and performing its best.
