My ‘Color Flash’ astilbe isn’t wasting any time on the flash this year. The foliage emerges lime green and slowly changes to burgundy-purple as the summer progresses. In fall the leaves morph into even brighter shades of red or bronze.

‘Color Flash’ grows 10 inches tall and spreads about 20 inches. In summer the plants send up light-pink plumes that reach 15 or 20 inches tall.
‘Color Flash’ is hardy in Zones 4-9.
