Neutral coriaceous On Nov 23, 2014, coriaceous from ROSLINDALE, MA wrote:

Flowers appear white or the palest silvery blue-violet. Comes true from seed. Seed is commercially available.

In the Chicago Botanic Garden's 2004 hardy geranium evaluations, this managed a rating of "fair". It was among the least floriferous of G. pratense cultivars tested.

In Chicago, it was 18" tall and 24" wide. Perhaps it is taller in the South. This is among the species whose flowering stems can topple if unsupported and require cutting back after flowering.

Requires good drainage and regular moisture. Tolerates soils of higher pH than most hardy geraniums.

Armitage says that this species is hardy in Z5-7 in eastern N. America.
