Heuchera grows best in partial shade, in not too dry soil. It is better not to place Heuchera in full sun as the beautiful leaves can burn. Heuchera is excellent for planting under a slightly translucent ornamental shrub, in a large planting bed or as a border planting. Every 3 years rejuvenate the plants, pull out and remove the long rhizome, replant the small separate plants with small roots and a little rhizome.
