Botanical Description

Douglas ex Lindl. 2B. This member of the series Californicae forms clumps 15-30cm tall. Leaves deciduous, grassy, 3-5mm wide, light green. Flowers 7-9cm across, deep blue-purple to pale lavender, also cream and yellow, early summer. Washington State and Oregon, on open hillsides and in woodland. I.t. subsp. klamathensis has buff-yellow to creamy-pink flowers having maroon to brownish veining. It also has a distinct tube between the base of the falls and the ovary (in I. tenax itself this is no more than a short collar). North-western California only and rare in the wild. A graceful species which does well in British gardens. [Pl.229]
