Some may consider Centranthus ruber, or Jupiter's Beard, old-fashioned, but it is still popular for its ease in growing, its non-stop blooming, and the lovely cut flowers it makes.  This rose-colored variety grows from one to three feet tall in sun/partial shade (it may get floppy with too much shade) in Zones 5-10.  And, as you may have noticed, butterflys enjoy it, too. Quarts.  Sold Out! More Later - stay tuned.
