Bigroot geranium (Geranium macrorrhizum 'Bevan's Variety') is a semi-evergreen perennial that spreads into a dense, weed-suppressing ground cover while requiring almost no maintenance once established. This hardy rhizomatous plant grows 9 to 12 inches tall but spreads 18 to 24 inches wide, thriving in zones 3 through 8. What makes it truly special is its combination of aromatic, deeply lobed foliage that turns russet in autumn and showy purple-pink flowers that bloom from April through July. The thick rhizomes underneath do the real work here, storing enough water to keep the plant thriving even during droughts, making it one of the most resilient geraniums you can plant.

Deeply lobed grayish-green leaves release a pleasant fragrance when brushed against or crushed, and they shift to attractive red tones as temperatures cool. Long-lasting purple-pink flowers with dark red calyces appear over an extended four-month bloom window. The thick rhizomatous root system tolerates drought and hot, humid summers better than most other geranium species, while the dense growth habit naturally crowds out weeds without any effort from the gardener. Deer and rabbits leave it alone, making it a rare ground cover that survives intact in wildlife-pressured landscapes.
Bigroot geranium excels as a ground cover for slopes, banks, and other areas prone to erosion where you want attractive year-round foliage without constant maintenance. Its dense spreading habit and weed-suppressing growth make it ideal for naturalizing into drifts across larger garden spaces. The extended bloom period and pollinator appeal also make it valuable in meadow gardens and informal plantings where butterflies are encouraged.
