ERIOPHYLLUM. Sunshine daisy, woolly sunflower. Western North America. This is a small group of both annual and perennial, sometimes even shrubby daisies, often found in dry, exposed habitats; they are among the classic roadbank plants of California. The perennial sorts are mostly small, closely branched and woody at least at the base. They have small, white-woolly, usually divided leaves and similarly woolly stems. Cheery yellow flower heads are elevated above the foliage, singly or in clusters, on slender stalks. Several are candidates for the rock garden and dry border, and all are interesting additions to sunny banks. They tend to be short-lived but are easily restarted from seeds and cuttings. Full exposure, well drained soil, moderate to infrequent watering when they are established. Their hardiness varies considerably.
lanatum. A semishrubby perennial of quite variable size and habit. It is matting to mounding in habit, with nearly white leaves and stems. The flower heads are borne singly or in small groups, each ½" to nearly 2" broad. The varieties achillaeoides and grandiflorum are plants mostly of the interior. Both grow normally upright to a height commonly 8-18". The latter, as its name implies, has the larger flower heads, up to 1½" broad. Both can take nearly any degree of drought. The variety arachnoideum is less shrubby and usually prostrate, especially in the commonly cultivated forms, but has similar flowers. It makes an interesting small scale ground cover. This one needs more summer watering to look its best. 10oF or less.
nevinii Canyon Silver. This is a selected form of the most shrubby species, found on some of the Channel Islands. It grows about 3 high, with greater spread. The twice-divided leaves are up to 8" long, quite broad and flat. It has yarrow-like clusters of small, short-rayed flower heads. The overall impression is that of a large, somehow more interesting dusty miller. Probably around 20oF.
