Description: Austrocylindropuntia subulataSN|4092]]SN|4092]] is native to high elevations in Ecuador and Peru and forms an tree-like, branching specimen with time.
Crested form: The crested form (Austrocylindropuntia subulataSN|4092]]SN|4092]] f. cristata) creates very wide undulant fans topped shapes with combs of long emerald green succulent leaves with white areoles, and few (but fierce) white spines. In the crested form the cells at the tip of the branch where growth occurs begin to multiply at a much faster rate and the normal growing tip "goes crazy", creating fantastic whorls and fans with pronounced sculpture effects. The crested branches slowly form delightful, snaky, ridged or crowded hemispherical clusters. The plant often grows a fast growing cylindrical stem to reveal its origins.

Make sure your Opuntia subulataSN|4096]]SN|4096]] is not exposed to temperatures below -4°C or it may die. Nevertheless it is a good advice never let the night-time temperature fall below 5°C. Water regularly in summer, but allow to dry fully before watering again. It needs a well-drained soil mix, with small gravel added to ensure drainage. During the winter months it should be rather kept dry, and water is restricted to only enough to keep the stems and branches from shrivelling. Since these are big sized plants, and they need plenty of space for their roots, repotting should be done every other year, or when the plant has outgrown its pot.
Propagation: Cuttings in summer (Cuttings will root only in hot weather)
