Blackfoot daisy

Melampodium leucanthum

Family:
Asteraceae
Elevation:
2,000 ft – 6,500 ft
Bloom:

Region:
Southwest

A tidy, low mound smothered for much of the year in small white daisies with sunny yellow centers, giving off a faint honey scent. One of the longest-blooming and most dependable native groundcovers of the Southwest.

Care · tuned to the Southwest

Water

Very drought tolerant; water sparingly. Overwatering and heavy, poorly drained soil are the top causes of a short life and rot. Perks up and reblooms with monsoon rains.

Sun & exposure

Full sun; tolerates reflected heat. Too much shade causes flopping and sparse bloom.

Soil

Insists on excellent drainage — rocky, gravelly, sandy, or caliche soils are ideal. Naturally a limestone/alkaline plant; avoid rich, moisture-holding soil.

In the Southwest

Cold hardy to around 0°F. Often short-lived but reseeds modestly to renew itself. A light shearing tidies the mound and prolongs bloom. Nectar source for small native bees and butterflies.

Common problems & fixes

  • Root rot in heavy or wet soil — young plants collapse in clay or overwatered beds

    Fix — Plant in gritty, sharply drained soil, water sparingly, and keep water off the crown.

  • Short-lived but self-sows — plants fade after a few years, leaving gaps

    Fix — Leave spent flowers to reseed and thin volunteers, treating it as self-renewing rather than permanent.

Pets & toxicity

Not known to be toxic to dogs or cats.

Easy to confuse with

  • Desert zinnia (Zinnia acerosa) — narrow needle-like leaves and creamier petals
  • Angelita daisy (Tetraneuris acaulis) — all-yellow flowers on leafless stalks
