Unusually big 8-10" leaves in shades of burgundy and red that develop a have a silvery cast. Sprays of white flowers appear in late spring, after other selections are finished. Very sturdy habit, an excellent choice for hot, humid summer regions. An introduction from French breeder Thierry Delabroye. The Heuchera villosa bloodlines in this hybrid contribute a velvety leaf surface, later flowering habit and exceptional sturdiness. [heuchera magnum.jfif]

Or take the the opportunity to divide the clump, ideally in spring, by breaking off the woody bases where they join, replanting the individual rosettes (don’t worry if they have few or no roots) and discard the remainder.
