These tough, drought-tolerant plants produce masses of small daisies over a long period. Provide well-drained soil.
M. cinereum. HOARY BLACKFOOT. Perennial. Zones LS, CS; USDA 8-9. Native to limestone soils of Arkansas, Colorado, and Texas. To 412 in. tall and wide. Similar to M. leucanthum but not as hardy; blooms from spring.
M. divaricatum. STAR DAISY, BUTTER DAISY. Annual. Zones US, MS, LS, CS, TS; USDA 6-11. From Portugal and Spain. To 13 ft. tall and half as wide, with narrow, dark green leaves and deep yellow daisies throughout summer and into fall (no deadheading required). Start seeds indoors for earliest bloom; or sow in ground after soil has warmed. Plants will also self-sow. 'Medal- lion' grows to 3 ft. tall and often becomes leggy by midsummer. 'Melanie' and 'Million Gold' are a lower-growing selection (1 ft. high) that blooms prolifically. Dense-growing 'Showstar' is also more compact than the species (to 112 -2 ft. tall), with showier blooms; 'Derby' is similar, but it's a little shorter and more compact still. 'Casino Light Yellow' averages 12 in. tall and is a compact, heavy bloomer both in ground and in containers, but it can split in late summer. 'Lemon Delight' is less vigorous and more compact than 'Casino Light Yellow' with bright yellow flowers. All tolerate heat and humidity, perform well in full sun or light shade. Perfect for the front of a border or container.
M. leucanthum. BLACKFOOT DAISY. Perennial. Zones US, MS, LS, CS, TS; USDA 6-11. From Arizona, New Mexico, Texas, Mexico. Wiry stems set with narrow, gray leaves form a clump to 1 ft. tall and wide. In spring, summer, and (in mild climates) sporadically in winter, the foliage clump is topped by clouds of inch-wide, honey-scented white daisies with yellow centers. Deer resistant.
