Echinocereus engelmannii

Engelmann's hedgehog cactus usually grows in clusters, sometimes up to 20 and more stems. The bright magenta flowers bloom in April in its southern extremes to late May at northern locations. Flowers are borne at the upper half to one third of the stem and are funnelform in shape, up to 3.5 inches (8.9 centimetres) long with dark-green stigmas. The fruit is spiny. At first the fruit is green, becoming pink and drying when ripe. Ripe fruits have spines that are easily detached. Seeds are black and about a tenth of an inch in size. Spines are variable in color and size. Radial spines are short and needlelike, up to 0.8 inches (2.0 centimetres) long, white, and arranged in a neat rosette. Central spines number 2 to 7 and are stout, usually twisted and angular, up to 3 inches (7.6 centimetres) long and variable in color.
