Colletia is a genus of flowering plants in the family Rhamnaceae, with 15 to 17 species of spiny shrubs. All species of this genus are native to southern South America.
Water:
Colletia, originating from arid regions, thrives with minimal moisture and shows excellent drought tolerance. It needs watering every two weeks, with decreased frequency in cooler months. This evergreen plant retains its foliage year-round, suitable for both indoor and outdoor cultivation.
Propagation:
Colletia can be propagated via semi-hardwood cuttings (4-6 inches) or seeds, requiring well-drained soil, consistent moisture, and bright, indirect light. Challenges include using rooting hormone and slow root development. Bottom heat and avoiding waterlogged soil enhance rooting success.
