This Californian species is remarkable for its twining habit, the flower-scape often reaching the height of 7 or 8 feet or even more. The flowers are produced in terminal umbels of from fifteen to thirty each, the perianth being of a light rosy-purple color, nearly 1 inch long, of a tubular ventricose form, contracted below the mouth. The foliage is linear, somewhat fleshy in character, and from 12 to 18 inches in length. It is perfectly hardy, and of the easiest cultivation in any soil, but will probably succeed best in sandy loam. Seedlings will bloom the third year of their growth.- Garden.
