Cream Pincushions (Scabiosa ochroleuca; Dipsacaceae), a New Established Exotic Plant in Eastern Canada

Ross A Layberry, Paul Catling

Abstract


An established population of Cream Pincushions (Scabieuse jaune pâle, Scabiosa ochroleuca L.) in the Ottawa Valley approximately 16.5 km southeast of Arnprior is new to the flora of Ontario and eastern Canada. Other Canadian reports include a nonpersisting occurrence in Victoria, British Columbia, in 1908 and a recent occurrence from Keremeos in southcentral British Columbia. Identification and ecology of this species are discussed. In the Ottawa Valley, the plant occurs with introduced Heath Snail (Xerolenta obvia), which also originates in eastern Europe.
