Indigofera pellucida J.B.Gillett & Thulin is a perennial plant that belongs to the family Fabaceae. This species is native to Africa and is mainly found in Sudan, Ethiopia, and Eritrea. Propagation of the plant can be done either by sowing of the seeds or through cuttings.
Propagation by Seeds
The seeds of Indigofera pellucida J.B.Gillett & Thulin can be sown directly into the garden during the spring or summer season. The soil should be well-draining, fertile, and moist. The seeds should be sown at a depth of around 2 cm and should be covered with a thin layer of soil. The seedlings should emerge within 2-3 weeks, and once they have grown a bit, they should be thinned to the desired spacing.
Propagation by Cuttings
Propagation by cuttings is another effective way to propagate Indigofera pellucida J.B.Gillett & Thulin. Select a healthy stem from the mother plant that is around 10 cm long and has a diameter of 3-4 mm. Cut the stem below a leaf node and remove all the bottom leaves, leaving only the top two to three leaves. Dip the cut end of the stem in rooting hormone powder and place it in a well-draining soil mix. Cover the pot with a plastic bag to retain moisture and place it at a location where it can receive bright, indirect sunlight. The cutting should develop roots within 2-4 weeks, and once you see new growth, you can remove the plastic bag.
