Plains Blackfoot or Blackfoot Daisy (Melampodium leucanthum) has been added to my Wildflowers of Tucson, Arizona website.
These native, perennial subshrubs have beautiful white and yellow daisies that are 1.5 inches (3.8 cm) across. Like other members of the Aster Family (Asteraceae), these plants have compound flowers (flowerheads) composed of central disk flowers and outer ray flowers. Plains Blackfoot flowerheads have golden yellow disks and a ring of notched, white rays.
These attractive plants make excellent additions to xeriscape gardens, and they do best in sunny locations with good drainage. In Arizona, depending on the growing conditions, Plains Blackfoot plants bloom anytime from March to December. Here in the Tucson area, these wildflowers mostly bloom in the summer after the monsoon rains have begun.
