It grows well in my garden and survives our rigorous weather well. In fact it can become somewhat of a nuisance with its rampant growth habit. It spreads quickly to form dense mats. From summer to the first frost pale blue to lavender, saucer-shaped flowers are borne in loose cymes on long petioles above the dissected foliage. This plant thrives best in sunny sites in a fertile moist soil.
Plants are clump-formers with hairy stems.
Leaves are deeply dissected with 7 to 9 divisions, each of which is deeply toothed. It will grow in moist soil in a sunny site. Quite a few cultivars of this species are available. Geranium clarkii a native of Kashmir is a spreading, rhizomatous plant with 7-lobed basal leaves with each lobe being deeply cut into narrow, pointed segments. This species tolerates wet conditions better than most.
