Sandy fields and plains, open oak forests, sometimes in ± disturbed ground as along roadsides. The natural range in the state seems to be north to southernmost Oceana Co. (south of the South Branch of the White River); farther north presumably escaped from cultivation. The fruits are dull dark red, fleshy, and spineless. The western Opuntia polyacantha Haw. is sometimes cultivated in yards and sandy cemeteries for its more colorful flowers, ranging from yellow to pink or magenta. It is a more spiny plant with dry, brownish fruits that are usually spiny.
