"Outstanding Qualities
This long-cultivated English selection has proven to be a time-tested classic. 'Mavis Simpson' is vigorous and easy to grow. Established plants can reach 4 feet across, making this an excellent groundcover. Clear pink flowers are produced all season, beginning in late May. Silver-tinted foliage adds additional interest.This low-maintenance plant does not seed around and become a nuisance as do some Geranium oxonianum hybrids. If it gets out of bounds, cut it back as needed. Do not plant it near smaller growing plants as it will shade them out. 'Mavis Simpson' is a dependable, long-lived perennial. It combines best with pastels and cool colors

Culture Notes This hardy geranium prefers full sun but tolerates part shade. Plant it in average, well-drained soil. Cut the stems and leaves to the ground in late fall. Divide the plant every third year, in fall, to keep it vigorous and to keep the center of the plant full. If your garden has a high population of root weevil pests, they may eat this geranium. Consult your local nursery if you see notches on the edges of the leaves."
