Yellow Sleepy Daisy (_Xanthisma texanum_) is a yellow daisy with lazy habits, for the heads do not open until noon. It is close kin to the white lazy daisy (_Aphanostephus skirrobasis_), and the two may often be found growing in the same fields. The large heads of lemon-yellow flowers are quite showy and attractive, 1½ inches broad, solitary at the ends of the branches. The ray flowers are narrow, about one inch long, and conspicuously lance-shaped at the tips.
This plant blooms in the late spring and summer and is found on sandy prairies or open woods in Central Texas. It is an annual, the stem branched above, commonly about 1-1½ feet high. The leaves are glossy green, somewhat narrow, and one to two inches long. It has been introduced into cultivation in the North and East. The name is Greek, meaning “dyed yellow.”

Berlandier’s Golden Aster (_Chrysopsis berlandieri_) is common on roadside banks and prairies of Central and West Texas. Growing from a perennial root, the branched stems sprawl in clumps about a foot broad and are thick with yellow heads soon after a heavy rain. The heads are nearly an inch broad, the flowers all yellow. The leaves are whitish and somewhat woolly. It blooms in the summer and fall.
Spiny-Leaved Yellow Aster. Iron Flower (_Sideranthus spinulosus_) has yellow heads much like the preceding, but the leaves are quite different, being divided into narrow segments which are bristle-pointed rather than spiny as the name indicates. “Sideranthus” means “iron flower.” It is very abundant on prairies and hills in the western part of the state and ranges to Canada and Mexico. It blooms from March to October. The iron flowers are often called gold daisies. The southern iron flower (_Sideranthus australis_) is common in Southwest Texas.

White Lazy Daisy (_Aphanostephus skirrobasis_) grows very abundantly in sandy soil in spring and summer. It ranges from Kansas to Mexico and Florida. The morning traveller does not appreciate its beauty, for it is truly a lazy daisy, not opening its heads until nearly noon. The plants are usually branched and grow 6-18 inches high. The large, showy heads are 1-2 inches across and are usually long-stalked. Unlike those of many other daisies, the seeds are not topped by slender bristles but have an inconspicuous crown, as is denoted by the scientific name, which is Greek for “faint crown.”
