Chamaecerus is a low-growing cactus that is cylindrical, ribbed, and spiny. It is often grown indoors for its abundance of bright-red blossoms.

Chamaecereus has short branch joints from its base that produce a clumping, fingerlike effect. Flowers appear when this cactus is quite young making it one of the most popular of all cacti.
