Propagation of Clerodendrum capense Eckl. & Zeyh.
Clerodendrum capense Eckl. & Zeyh., commonly known as the Blue Butterfly Bush, is a beautiful flowering plant that belongs to the Lamiaceae family. The plant is native to South Africa and is popular for its blue-purple flowers and attractive foliage. Propagation of this plant is relatively easy, and there are several methods that can be used to propagate it.
Propagation by seed
Propagation of Clerodendrum capense can be done by seed, which is the most commonly used method. The seeds of the plant can be collected from mature fruits and sown in well-draining soil. Before sowing, the seeds should be soaked in water for a few hours. The seeds should be planted at a depth of 2-3 cm and kept in a warm, bright location. The seedlings will emerge within two weeks, and once they develop their first set of true leaves, they can be transplanted to larger containers or directly into the ground.
Propagation by softwood cuttings
Clerodendrum capense can also be propagated by softwood cuttings, which involves taking a cutting of a new growth shoot in late spring or early summer. The cutting should be 5-10 cm in length and should have at least two nodes. The lower leaves should be removed, and the cutting should be dipped in rooting hormone powder before being planted in well-draining soil. The cutting should be kept warm and moist, and roots should appear within one to two months.
Propagation by semi-hardwood cuttings
Semi-hardwood cuttings can also be used to propagate Clerodendrum capense. The cuttings should be taken from the current season's growth midway through the growing season and should be 10-15 cm in length. The lower leaves should be removed, and the cutting should be dipped in rooting hormone powder before being planted in well-draining soil. The cutting should be kept in a warm, bright location and will develop roots within two to three months.
Overall, Clerodendrum capense is an easy-to-propagate plant, and with proper care, the cuttings or seeds will develop into healthy plants.
Disease and Pest Management for Clerodendrum capense Eckl. & Zeyh.
