This thrives in any soil, whether wet or dry. Up to nine elegant, blue-purple flowers are produced on long, arching, slender, well-branched stems. The flowers have slim petals, and the standards are shorter than the falls. The falls are veined with soft yellow. The broad, grey-green foliage is stained at the base with purple and grows into broad, gracefully arching clumps. Blooms during late June to July.
