Opuntia brasiliensis - Tree cactus with flat segments and edible fruits

Opuntia brasiliensis, currently also botanically known as Brasiliopuntia brasiliensis, is a cactus with an unusual and highly decorative appearance, valued for its upright, shrubby to tree-like growth habit and for the combination of cylindrical stems and flat, green lateral segments.

As it matures, the plant can develop a well-defined trunk and a branched crown, taking on the appearance of a small exotic tree. It is suitable for cactus collections, greenhouses, sunny terraces during the warm season, or very bright interiors.

Mature specimens can produce yellow to yellow-orange flowers, followed by decorative fruits that are considered edible.

Note

The shape, degree of branching, segment length, and spine density may naturally vary from one specimen to another.

The segments may show small scars, spots, scratches, or corky areas resulting from growth, handling, or transport. These features do not normally affect the plant's viability.

Although the fruits of mature specimens are considered edible, the plants sold by Secret Garden are sold exclusively as ornamental plants and are not certified for food consumption.
