Tufts of needle-like, juvenile foliage give this rounded, light-blue selection of 'Tsukumo' its airy character, even when mature. Named for a look like puffy clouds, this delicate choice adds a reliable element of soft texture to tight garden spaces. 'Cumulus' stays small without pruning; its foliage is most dense when grown in full sun. Particularly useful for container, trough or rock gardens and other small sites. (Iseli Nursery Description)
