Rock’s Variety

Rock’s Variety or Joseph Rock.  Rock.  (Unregistered).  Suffruticosa with P. rockii influence hybrid. Chinese Gansu-mudan.  White single flowers of large size.  Sometimes flushed with pink when flowers open and then turning white quickly with age.  Large dark maroon basal flares.  Maroon stamens, cream sheath and stigmas.  Strong growing plants become large over time, 5 feet or more and 7 feet wide in Wisconsin.  Beautiful foliage with long leaves divided into many leaflets.  Very winter hardy. These are grafted plants and are guaranteed to be authentic (no surprises).  Often sold as Paeonia rockii, but it is actually a hybrid. Excellent.  Fertile and a superior parent.  Recommended for cold winter climates.   Heavily used in American hybridizing programs and a number of cultivars with the same name are grown in Europe.   Originally this plant was thought to be the species P. rockii, but genomic work has now revealed it as a hybrid with a P. suffruticosa cultivar in its heritage.  Hybrids from Rock’s Variety are extremely hardy and produce a multitude of outstanding offspring.  A historically interesting plant, as well as, a superior garden plant. Ships in late September to mid October.  AGE: Field grown, 4+ year old graft or division from larger plants – our choice of available plant material upon harvest.
