In the summer, the leaves become greener with a silvery overlay. ‘Miracle’ is further characterized by its mounded and compact plant habit, its hardiness at least in U.S.D.A Zones 4 to 9, its tolerance to heat and humidity, its vigorous growth habit, and its spikes of pink flowers in late spring to early summer.
