Geranium incanum can
produce a wealth of color on an easy to grow plant. I space the
plants about 18" on center. They will readily replace their
lost brethren if the area gets disturbed. Geranium incanum can get by with
no additional water in coastal areas and will persist with very moderate
irrigation requirements in inland locations. Ours have survived
quite nicely in temperatures that dip into the low 20's and shown a little
reddening of the leaves in the high teens.
