Strong growing with a distinct upright look, 'Flamingo' will gladly show off its pale blue, mop head type flowers held above the foliage on thick, strikingly black contrasting stems. While 'Flamingo' is a strong grower, it is never out of control and is the perfect landscape resident with its long summer color that is bolstered by additional bud and bloom as the season lengthens.
Fertilize yearly with an organic fertilizer. Prune in summer months as blooms fade for best flowering results next season. Tight, compact form needs little pruning.
