Description

Cleistocactus hildegardiae grows as a shrub with often richly branched, spreading shoots that reach heights of 20 to 50 centimeters with diameters of 2.5 to 3.5 centimeters. There are 15 to 19 low, wavy ribs. The areoles on it are close together. The thorns are needle-like and straight. The 5 to 8 central spines are golden yellow to reddish brown and 1 to 3 centimeters long. The 18 to 28 light yellow marginal spines are 3 to 8 millimeters long.

The ruby red flowers are 2.5 to 3.5 centimeters long. The spherical, dark green fruits later turn orange and reach a diameter of up to 1 centimeter.[1]
