Campanula 'Birch Hybrid' (Birch's Bellflower) - This plant is a vigorous spreading evergreen perennial to 6 inches tall by 18 inches wide with tough, arching, prostrate stems and small toothed reniform shaped leaves rising up on long petioles. Over a long period from late spring through mid-summer emerge the large clusters of upward facing open bell-shaped flowers that are deep iridescent violet - blooms reliably for a long period and can be extended by deadheading. Plant in full coastal sun to light shade and give regular irrigation. Hardy to 5 F and useful from USDA Zones 5 to 10. Foliage is not attractive to deer or rabbits. This plant is a nice showy small scale ground cover for an irrigated area and also makes great container plant. It comes from the historic Birch Farm Nursery operated by the Ingwerson family in West Sussex, England and is noted as having one of the longest flowering displays of the smaller campanulas. This hybrid is sometimes listed as a Campanula poscharskyana selection but is thought to actually be a hybrid of this species with Campanula portenschlagiana, though it is noted as not being as aggressively invasive as this later species. It was selected as a Great Plant Picks for the Pacific Northwest by The Elisabeth Carey Miller Botanic Garden and was one of Pacific Horticulture 2009 Great Plant Picks. For more information on the parent species see our listings of Campanula portenschlagiana and Campanula poscharskyana
