Plant name: Bigroot geranium
Botanical name: Geranium macrorrhizum
Virtues: An easy-to-please groundcover that chokes out weeds and looks nice from spring right through fall.
Flower: 5-petaled pink flowers appear in late spring. Can rebloom in summer.
Foliage: Deeply lobed and fragrant, the green leaves turn reddish bronze in fall.
Habit: Clump-forming groundcover that spreads by thick rhizomes. Grows 12 to 18 inches high.
Season: Spring through fall.
Origin: Southern Europe
Cultivation: Average soil, full sun to partial shade. Stands up to drought and hot summers. A good companion for summer- and fall-flowering bulbs, as it fills in gaps before they bloom, and can be sheared back when they come into bloom. Can self-sow; remove spent flowers to avoid this. USDA Zones 3–8.
