📌 Note

The appearance and density of the spines, as well as the plant's shape, may naturally vary from one specimen to another. Plants are sold without flowers.

Flowering depends on the plant's maturity, light intensity, and dormancy conditions during the cold season. Excess water, especially at low temperatures, can quickly damage the root system.
