The stems of "Glory of Texas" are solitary, grayish blue-green and ususally egg-shaped. They may reach 8" in height and 4 or 5" in diameter. The long central spines are flattened and flexible, white and pink-red in color, and get up to 3" or more in length.
The spectacular flowers are brilliant satiny fuschia with deep scarlet throats, often growing to 4"in diameter. They bloom from April - June. The fruits are about 1/2" long and are green and dry at maturity.
