Heuchera micrantha is an herbaceous perennial. It has maple-like leaves that are deep purple, changing to bronze-green in hot summers. During the summer months, h. micrantha develops long stems that are covered in bluish-white bell-shaped blooms. H. micrantha should be planted in a partially shade spot with well-drained soil that retains moisture. In a sunny aspect, it’s vital that the roots are not allowed to dry out. H. micrantha is an attractive garden specimen that provides year round interest, and works well in containers, herbaceous borders and rockeries.
