Introduced by the U.S. Arboretum, this stunning selection will electrify your summer landscape with 4+" diameter single flowers with deep red spots at the center from mid July through early September. These Hollyhock-like flowers are showy and plentiful as they fill up this upright growing selection that is slightly smaller that some other Rose of Sharon but still substantial enough to perform equally well as a stand alone specimen of to be grouped to form a beefy, blooming summer headge. 'Minerva' is an easy care wonder that just wants a sunny spot, well-drained soil and someone to admire its brilliant summer show!
