Propagation of Vernonia pteropoda Oliv. & Hiern
Vernonia pteropoda Oliv. & Hiern, commonly known as Ironweed, is a stunning perennial plant that grows up to 3 meters tall. The plant is native to Africa and is commonly found in Ethiopia, Kenya, Tanzania, and Uganda. Propagation of Vernonia pteropoda Oliv. & Hiern can be achieved by the following methods:
Propagation by Seed
The seeds of Vernonia pteropoda should be sown in the spring. A well-draining soil mix should be used to sow the seeds. Before sowing the seeds, they should be soaked in water for 24 hours. Sowing should be done at a depth of 2mm. The soil should be kept moist at all times, and germination usually takes around 21 days. Once the seedlings have developed two or three sets of true leaves, they should be pricked out and transplanted into individual pots. The seedlings should be grown in a warm, bright location until they are large enough to be transplanted into their final growing position.
Propagation by Cuttings
Vernonia pteropoda Oliv. & Hiern can also be propagated by stem cuttings. Cuttings should be taken during the growing season, preferably in the spring or early summer. The cuttings should be around 10cm long and should be taken from healthy, disease-free plants. Remove the leaves from the bottom half of the cutting and dip the cut end into rooting hormone. The cuttings should then be placed in a well-draining soil mix and should be kept moist. After around six weeks, the cuttings should have rooted and can be transplanted into their final growing position.
Propagation by Division
Propagation by division can be done in the spring or fall. The plant should be carefully dug up and the clumps divided using a sharp knife. Each division should have a healthy root system and should have at least two shoots. The divided clumps can then be replanted into their final growing position.
Propagation of Vernonia pteropoda Oliv. & Hiern is relatively straightforward, and by using the methods outlined above, gardeners can quickly increase their stock of this stunning and versatile plant.
