Propagation of Astridia blanda L.Bolus forma angusta L.Bolus ex H.Jacobsen
Astridia blanda L.Bolus forma angusta L.Bolus ex H.Jacobsen, commonly known as the Cape tulip, is a flowering plant species that belongs to the family Iridaceae. The plant can be propagated via various methods, including:
Propagation through Seeds
The easiest and most commonly used method of propagation for Astridia blanda L.Bolus forma angusta L.Bolus ex H.Jacobsen is through seeds. The plant produces seeds in large numbers, which can be collected once they are mature. After collecting, the seeds need to be cleaned of any organic debris and dried well.
