Cummings 1967. S. villosae group. Deep rosy-pink blooms. Flowers late in the season. Zones 2-7. 6′-9′ feet tall at its best but will easily grow twice that size.  The largest local specimen we are familiar with is growing at Amanda’s Greenhouses in Cabot, Vermont to the front and right of the first greenhouse. Easily 12′ X 12′–perhaps a little more.
