Cochemiea

Clumping cactus, irregularly forming clusters up to 1 m across or more. Flowers large, spectacular, zygomorphic bright scarlet. Not the most easy to grow but worth trying. Be careful with too much water and give it good ventilation. Strong spination.

A small, cereus-like Mammillaria: solitary when young, it forms irregular clusters with age. Stems are hidden beneath dense hooked spines. Showy, long, bright red, zygomorphic flowers are adapted for hummingbird pollination.
