Propagation of Pentas Purpurea Oliv. var. Buchananii Verdc.
Pentas purpurea Oliv. var. buchananii Verdc., commonly called the Egyptian star cluster, is a popular flowering plant in tropical and subtropical regions. It is mainly propagated by seeds, cuttings, and division.
Seed propagation
Propagation by seeds is the most common method of producing Pentas purpurea Oliv. var. buchananii Verdc. It is also the simplest way to propagate the plant.

The seeds should be sown in a well-draining potting mix, covered lightly with soil, and kept moist until they germinate.
Cutting propagation
Cuttings are another method of propagation for Pentas purpurea Oliv. var. buchananii Verdc. The cuttings should be taken from a healthy mother plant and should be at least 4 inches in length. The lower leaves should be removed, and the cuttings should be dipped into a rooting hormone before being placed in a well-draining potting mix. The cuttings should be kept moist and warm until they root, which usually takes 3-4 weeks.
Division
Division is the third method of propagation for Pentas purpurea Oliv. var. buchananii Verdc. It is best done in spring when the plant is just starting to grow. The plant should be dug up carefully, and the root ball should be divided into smaller sections. Each section should have a healthy shoot and a good root system. The divisions should be replanted immediately in a well-draining potting mix and kept moist until they are established.
