Arizona Sun Blanket Flower
Arizona Sun Blanket Flower
The Classic Red-and-Gold Daisy That Blooms All Summer
Arizona Sun Blanket Flower (Gaillardia aristata 'Arizona Sun') is the award-winning blanket flower that put the whole group on the map — mahogany-red blooms ringed in bright gold, carried nonstop from early summer to frost on a neat, compact plant. Despite the cultivar name, it's a descendant of the tough native prairie blanket flower and is fully hardy to zone 3, thriving in hot, dry Minnesota borders in Bloomington, Plymouth, and Lakeville.
