Sulcorebutia arenacea f. monster (Cactus)

The monstrous shape of this plant is highly appreciated by green collectors. It’s a globular, bright green cactus with multiple defined ribs. It has white spines at the base, which gradually turn yellow-brown as they go towards the apex. In the hottest periods, the upper part of the plant is surrounded by a corolla of small white or pink flowers. It is a very popular plant for its geometrically accurate shape.
