Absolute Treasure. It's a relatively new one, and for me, grows and multiplies like crazy, with big, beautiful foliage and wondrous true light blue blooms, blended with white. It bloomed for me its first year, by the second year had made a large impressive clump, and even though the deer or groundhogs ate off all the new foliage last year, it bounced back and bloomed beautifully. And even though our horribly rainy Spring and Summer last year even rotted out our forsythia hedge, Absolute Treasure survived, has formed a wonderful clump, and is sending up a bunch of bloom stems in this, its third Spring. It's a thriver!
