Prairie Blackfoot Daisy. Mountain Daisy. Rock Daisy (Melampodium cinereum) is very abundant on limestone slopes and in dry soil from Texas to Arkansas, Kansas, and Arizona. The scientific name is from the Greek words meaning “black foot” and refers to the blackened roots and stalks.
Blackfoot Daisy (Melampodium ramosissimum) grows from a black woody base and has many branched stems which form a dense rounded mound one to two feet broad. After sufficient rainfall from early spring until winter, this mound is covered by the saucy heads of white daisy-like flowers. The heads are about three-fourths inch across and have an outer row of 8-11 broad white ray-flowers. This is the most vigorous one of the blackfoot daisies and makes an excellent plant for the rock garden. It grows in Southwest Texas. The seeds are enclosed in a thickened cornucopia-like floral bract which has a flaring rim and many warty projections.
PRAIRIE ZINNIA TEXAS STAR DAISY
Texas Star Daisy. Lindheimer’s Daisy (Lindheimera texana) shows its star-like flower heads early in the spring while the plants are low and the leaves are closely clustered. By June the plants are tall and widely branched above. This plant honors by its name Ferdinand J. Lindheimer, an early settler of New Braunfels and editor of the “Neu Braunfelser Zeitung.” Lindheimer began his collection of Texas plants in 1836 and continued until his death in 1879. With the assistance of Dr. George Engelmann of St. Louis and Dr. Asa Gray of Harvard University, Lindheimer’s collections between 1842 and 1852, representing more than 1400 species of plants, were classified and distributed to the leading herbaria of Europe and America. A part of this collection is owned by the University of Texas Herbarium.
Prairie Zinnia (Zinnia grandiflora) grows in low, rounded clumps from Kansas to Mexico and Arizona and blooms from June to September. The bright yellow ray flowers are nearly round and remain on the seeds. With age they become papery, and the yellow disk flowers turn reddish-brown. The common zinnia in cultivation was introduced from Mexico.
CUT-LEAVED DAISY. ENGELMANN’S DAISY
Cut-Leaved Daisy. Engelmann’s Daisy (Engelmannia pinnatifida) is closely related to the sunflowers but has the daisy habit of closing the flower heads at night and opening them in bright sunlight. It is one of the commonest plants on prairies from Kansas to Louisiana and Arizona and grows in dense patches along roadsides and pastures from April to July.
The rough, hairy plants grow one to three feet high and are topped by broad clusters of long-stalked, showy yellow heads which are 1½-2 inches broad. The divided leaves are short-stalked on the lower part of the stem and on the upper part have clasping basal lobes.
