Purple Cranesbill
Geranium x magnificum
1 gallon pot
 
A truly magnificent sight in the early to mid-summer garden, award-winning Purple Cranesbill is a hybrid hardy geranium forming dense mounds of large, 2 in. wide, rich violet-blue, heavily veined, saucer-shaped flowers atop a velvety, deeply-lobed foliage that turns red in fall.

While the flowering season of this geranium is fairly short (a couple of weeks), it is so intense and stunning that, coupled with this fall color interest, a garden spot should be dedicated to it. Particularly attractive with Lady's Mantle and Peonies.
