Polemonium yezoense "Purple Rain" (Jacob's Ladder)
The photo hardly does justice to this most unusual and attractive Jacob's Ladder. Polemonium yezoense "Purple Rain" is the showiest Jacob's Ladder I have ever grown. Not only are the flowers larger than most, but they are not the azure blue we usually associate with Jacob's Ladder. Instead, they are a beautiful shade of violet. That's not all that is different about this showy perennial: the ferny foliage is a tinted with purple. It is a prolific bloomer, too, so when it "rains," it really does pour with this flower. Growing to about two feet in sun/part shade in Zones 5-9. Quarts.
