Hoya sp. Kalimantan is a show-stopping species highly prized for its incredible leaf venation. The leaves are large, thick, and stiff, featuring a dark green surface with prominent, almost black veins that create a dramatic "callistophylla-like" pattern. Originating from the island of Borneo, this collector's plant is as much a foliage piece as it is a flowering plant, though it does produce beautiful clusters of cream and red flowers.
