Astelia Silver Shadow (syn. Silver Spear) An impressively architectural plant grown for its silvery foliage, Astelia Silver Shadow is a large, clump-forming, evergreen perennial with long, lance-shaped, silver-dusted leaves, up to 39”/1m long, longer where the plant is suited. In May and June, loose panicles of yellowish-green flowers are borne on long stems on female plants. Astelia Silver Shadow is not for colder gardens, but is good in milder, coastal areas, especially with the protection of a warm wall; it can be grown in large containers and brought into a cool greenhouse for the winter.
