Castellanosia caineana SEEDS

This cactus can reach heights of 5-6 meters, distinguishing itself with a lack of Cephaliums or pseudocephaliums and even of hair on the flowering areoles. Its spination is heteromorphic, featuring strong spines on the lower part of stems and only tufts of fine bristles on the apical flowering segments. Seeds are small, 1 mm long, and reddish-brown​ (Llifle)​.

For cultivation and propagation, Castellanosia caineana seems to be rare in cultivation. It requires a rich, particularly draining substrate and is very sensitive to rot in humid, low-temperature conditions. Repotting should be done in spring when roots become cramped, and the soil should be allowed to dry out between waterings. This plant prefers full sun and moderate water, thriving best in a warm, sunny location in well-drained soil. Seeds should be sown in such an environment, and though the plant can also be propagated from cuttings, seeds or semi-hardwood stems are preferred. The plant enjoys full sun and requires moderate watering​ (Llifle)​​.

This cactus serves as an ornamental plant in gardens and hedges, used for erosion control and as a windbreak due to its robust and resilient nature​​.
