Young Coleus venteri leaves are soft, stubbly and brightly pale green, their amply rounded blade bulges dominating among deeply sunken veins. The veins are translucent, the leaf margins rolled under, their toothing hidden and the petioles thick.

The soft, silvery white hairs, possibly some glandular, are sparsely scattered and uneven in length. Initial roundedness in the decussate leaf-pairs makes way for the overall triangular shape of mature blades (http://pza.sanbi.org).
