Christmas cholla

Cylindropuntia leptocaulis

Family:: Cactaceae
Elevation:: 1,000 ft – 5,000 ft
Bloom:: May – Aug
Region:: Southwest

A wispy, intricately branched cholla with slender pencil-thin green stems that lace through desert shrubs, nearly invisible until small greenish flowers give way to brilliant red berries that ripen in winter. Those festive scarlet fruits give it its common name.

Care · tuned to the Southwest

Water

Very drought tolerant; occasional deep watering in the growing season suffices, and it should stay dry through winter. Excess moisture promotes root and stem rot.

Sun & exposure

Full sun to light filtered shade beneath nurse shrubs, with plenty of reflected heat.

Soil

Requires gritty, sharply draining, often alkaline desert soil; tolerates rocky and sandy ground.

In the Southwest

Cold-hardy to about 0–10°F, the hardiest of these chollas. Stems bear short but sharp barbed spines and detachable joints; the long-lasting red winter berries are a key food source for birds.

Common problems & fixes

Stem and root rot from overwatering or wet clay
Fix — Grow in lean, gritty, fast-draining soil and keep dry in winter and cool spells.
Barbed joints hidden among shrubs snag people and pets
Fix — Site away from paths and pet areas and remove strays with tongs, never bare hands.

Pets & toxicity

Not chemically toxic; the thin barbed spines and brittle joints readily embed in paws and skin, and the unseen stems are easy for pets to brush against.

Easy to confuse with

Klein's pencil cholla (Cylindropuntia kleiniae) — thicker stems, longer sparser spines
Young tree cholla (Cylindropuntia imbricata) — stouter, tuberculate stems and magenta flowers
