Echinocereus knippelianus

 

A particularity of this plant is that the buds emerge through the plant's skin above an areole, rather than arising from areoles or axils between areoles as in other cacti.

 

Description: Solitary or slowly clumping cacti.
Stem: Plump, soft, flattened or globose , dark green with slightly lighter ridges, up to 10 cm tall, 8 cm in diameter.
Ribs: 5 to 7 ribs, either tuberculate or slightly wavy, separated by broad furrows.
Areoles: Small with whitish felt, 5 mm inches apart.
Spines: Nearly spineless,  with1 to 3 thin yellow spines, 3 to 15 mm long.
Flowers: Pink or white funnel-shaped flowers, 2.5-4 cm long, up to 6 cm in diameter, appearance in spring and summer. Flowers push through the body from the crown.
Fruit: Green berries near the stem tip
Root: Thick tuberous root that pulls the plant below ground to avoid the hot sun.

Cultivation: In culture E. knippellianus is without problems and regularly shows its pink flowers, if we provide an adequate winter rest period. It is sensitive to over-watering (rot prone), and needs good drainage.  Fertilize with half- strength liquid fertilizer in summer.  Keep drier and cool in winter. Needs full sun. Very cold resistant, hardy to -12° C or less for short periods of time.

Propagation: Seeds or cutting (if available)

 

 

The pale pink flowers are produced in spring.
