Heart It
Fanal AstilbeGreat for shadier spots on a rooftop,
Astilbe 'Fanal' rewards gardeners with rich crimson color that blooms
midsummer (typically July). A good perennial plant for the middle of the
border, astilbe shoots up stalks of about a foot and a half and is
hardy in Zones 3-8. It does best in moist soil; don't allow astilbe to
dry out.
