Asteraceae (Aster Family)



Melampodium leucanthum (Blackfoot daisy)
Bransford, W.D. and Dolphia
A low, round, bushy plant with flower heads of 8-10 broad white rays surrounding a small yellow central disk. Plains blackfoot or blackfoot daisy is a low, bushy, mounded perennial, 6-12 in. tall and twice as wide. It is covered with narrow leaves and 1 in. wide, white, daisy-like flowers. The white rays are toothed at the tips and surround yellow disk flowers. These honey-scented flower heads are solitary and terminal on slender stalks.

At first glance, Blackfoot Daisy appears to be the twin of White Zinnia (Zinnia acerosa), but flower heads of the latter species have 4-6 broad white rays and a narrow base of several overlapping scales. Both may be found in the same habitat, but the range of White Zinnia does not extend as far south as Blackfoot Daisy.

Soil Description: Dry, rocky, calcareous soils. Rocky, Gravelly Sandy, Limestone-based, Caliche type
Conditions Comments: Blackfoot daisy is a sturdy, mounding plant, that will flourish in rock gardens. It is heat and drought tolerant. Good drainage is essential to its success. In late winter, older plants can be cut back halfway to keep them compact. Rich soil and abundant water will likely produce many more flowers in the short-term, but may consequently shorten the lifespan.
