Horticultural & Botanical History

‘In point of colour, this is perhaps the most beautiful of all the numerous species of this Genus lately detected in North-west America by Mr. Douglas.  The flowers, not large, are first of a rich ultramarine colour, gradually, as the flower vecomes more expanded, the outside becomes of a deep purple, whilst the inside is much more inclined to azure blue.’  [BM t.2903/1829].  Introduced to Britain in 1826.  [PD].  ‘Damp rocky openings in the woods, Humid Transition and Canadian Zones; southern British Columbia, west of the Cascadean crest, to Multnomah County, Oregon.  Type locality: “High mountains about the Grand Rapids of the Columbia River.” May-July.’  [An Illustrated Flora of the Pacific States vol.III, p./746].
