Geranium tuberosum (F)
Hardy to Zone 6
Plant in full sun to part shade. Tuberous geraniums are early blooming, from April until mid June. For the rest of the summer they are dormant and all but disappear, so plant with late blooming beauties such as Lilies and Glads. These tuberous geraniums require dry soil, especially in their dormant state. Plant roots quite close to the surface, up to 3 inches deep.
