Gardeners' Notes:

Neutral coriaceous On Oct 18, 2014, coriaceous from ROSLINDALE, MA wrote:

Funnel-shaped flowers, white to silvery pink, marked with darker veins. Bloom continues intermittently over a long season.

Foliage can be evergreen in Z8, but here it's deciduous. Some cultivars have attractive brown-purple markings on the leaves.

I've grown a couple of cultivars, and I've found them to do well here (Boston Z6a). Reasonably vigorous, but none got over about 16" tall.

Most easily propagated by division. They self-sow a bit---not weedily or aggressively---but the offspring will not come true.

A naturally occurring hybrid between G. endressi and G. versicolor.

I'm as fond of the foliage of this geranium as I am the flowers. The leaves are large, and the margins are edged in a darker color.

Geranium oxonianum like most hardy geraniums is easy to grow. It has pretty pink/veined (different shades .... pale through bubblegum) of pink flowers. The foliage is nice like most hardy geraniums but not my favorite in a geranium.... its just ok. Not my favorite but not a bad geranium.
