Geranium caespitosum is a common middle elevation herb with purple flowers and deeply lobed leaves. The sepals are acuminate. There are ten stamens and five carpels. The fruit is a schizocarp with five mericarps. The mericarps each have an elastic hygroscopic awn that curls when ripe. Geranium caespitosum is found where the ground stays moist, frequently alongside creeks or in canyons.
