Named 'glory of Texas' because of its brilliant pink flowers, thelocactus bicolor
is an impressive but rare plant, found only in two small areas of Texas, though distribution is much more widespread over the border in Mexico. Flowers may be 4 inches in diameter, blooming from the top of the stem in spring and early summer, followed by greenish fruits.
Spines grow from adjacent tubercles along narrow, spirally-arranged ribs; there are usually between 12 and 20 radial spines, up to an inch long, and 0 to 4 central spines which are somewhat flattened, curved, pink or red (sometimes yellow) towards the tips, and up to 3 inches long. New spines are deep, rich red in color. Plants are usually single but may form small groups.
