Nelmesia melanostachya Van der Veken, also known as the black inflorescence or the Cape penstemon, is a dioecious plant that belongs to the family Plantaginaceae. It is an herbaceous perennial plant that can reach up to 90 centimeters tall.
Seed Propagation
The most common method of propagating Nelmesia melanostachya Van der Veken is through seed propagation. Collect the ripe oval-shaped seed capsules after they have turned brown, and split them open to obtain the numerous small seeds inside. Sow the seeds in a well-draining soil mix. Cover the seeds lightly with soil, and keep the soil mix moderately moist while the seeds germinate. In general, the seeds take two to three weeks to germinate, depending on the temperature and moisture levels.
Cuttings Propagation
Aside from seed propagation, Nelmesia melanostachya Van der Veken is also propagated by stem cuttings. This method is useful for preserving genetic traits of specific cultivars. Take 8-10 cm long cuttings from young shoots of the plant in early spring or fall. Remove the lower leaves and dip the base of the cutting in a rooting hormone. Plant each cutting in a pot filled with well-draining soil mix, and keep the soil moderately moist. Place the pot in a shaded location and protect it from extreme temperatures and direct sunlight.
Division Propagation
Another method of propagating Nelmesia melanostachya Van der Veken is through division propagation. Divide the plant in the spring or fall, when it is not actively growing, into smaller pieces with well-formed roots and buds. Replant each division, in a well-draining soil mix at the same depth as before, and keep it moderately moist. Provide partial shade for the first few weeks to avoid water loss through the leaves until the plant has established new roots.
In conclusion, Nelmesia melanostachya Van der Veken can be propagated using different methods, including seed propagation, stem cuttings, and division propagation. Each method has its advantages and disadvantages, depending on the gardener's skills, location, and time available.
