Paeonia 'Rock's Variety'

type: [tree peony] – [suffruticosa group] – [rockii-hybrid]

	Rock's Variety is a cultivated plant, deriving from Paeonia rockii. There are differences between the plants under the name 'Joseph Rock', which are derived from the seeds collected by Joseph Rock (and which brought a number of different cultivars, such as the so-called US-type or Arnold Arboretum form and the british type or Hidecote form) and the wild species (P.rockii (Haw & Lauener) Hong & Li ex D.Y. Hong ). Paeonia rockii is „characterized by leaves tri- (or bi-) pinnate; leaflets usually 19-33, very rarely less than 19; filaments yellow; floral disc yellowish white; Stigmata yellow and petals white but with a dark purple blotch at the base. “The cultivated forms differ more or less from this type in having purplish filaments, darker floral discs or stigmata not yellow.(Hong de-yuan 1998).
