Strophanthus gossweileri H.E.Hess x S. schuchardtii Pax ex H.E.Hess is typically propagated through seeds. However, it can also be propagated through stem cuttings, although this method is less common.
Seed Propagation
The seeds of Strophanthus gossweileri H.E.Hess x S. schuchardtii Pax ex H.E.Hess should be harvested immediately when the capsules start to split open. The seeds are then processed and sown in a well-drained soil mixed with some sand to improve drainage. It is best to sow the seeds immediately after harvesting to increase the germination rate.
The seeds should be pressed lightly into the soil and covered with a thin layer of sand. The soil should be kept moist, but not wet, until the seeds germinate. Germination typically occurs within two to four weeks.
Once the seedlings have developed two to three true leaves, they can be transplanted into individual containers. The young plants should be kept in a warm, humid environment with filtered sunlight until they are established.
Stem Cutting Propagation
Stem cuttings can be taken from mature plants during the growing season. The cuttings should be around 10-15cm long and taken from semi-hardwood, meaning that the stem should be firm but not yet woody.
The bottom of the stem cutting should be dipped into a rooting hormone and inserted into a well-draining soil mix. The soil should be kept moist but not too wet, and the cutting should be covered with a plastic bag to maintain high humidity. The cutting should also be kept in a warm, sheltered location with filtered sunlight.
Rooting typically occurs within 4-6 weeks. Once roots have developed, the cutting can be transplanted into a larger pot or directly into the garden.
