Thelocactus bicolor (Galeotti ex Pfeiff.) Britton & Rose
Thelocactus bicolor, the glory of Texas, is a species of flowering plant in the cactus family, widely distributed in the northern Chihuahuan Desert of the USA (Texas) and Mexico. Plants are usually solitary, but may form clumps.[2] Growing to 50 cm (20 in) tall, it is a perennial with spiny, ribbed, succulent stems. Large daisy-like flowers, up to 8 cm (3.1 in) in diameter, are borne in summer. The petals are purplish-pink, fading to white. The inner petal tips form a circle of red surrounding a prominent yellow boss.
This cactus is grown as an ornamental. A warm, dry, sunny spot in sharply-drained specialist cactus compost must be provided. It has gained the Royal Horticultural Society’s Award of Garden Merit.
