Propagation of Stachytarpheta elegans Welw.
Stachytarpheta elegans Welw. is an evergreen shrub that produces beautiful blue flowers. It is easy to propagate from both seed and cuttings.
Propagation from Seeds
The seeds of Stachytarpheta elegans Welw. can be collected from the dried flowers and sown directly into soil. Prior to planting, the seeds should be soaked in water overnight to help soften the hard outer coating. It is advisable to plant the seeds in a well-draining soil mixture that is rich in organic matter. The seeds should be covered with a thin layer of soil, and watering should be done regularly to keep the soil moist. Germination of the seeds usually takes about 2-3 weeks.
Propagation from Cuttings
Stachytarpheta elegans Welw. can also be propagated from cuttings. Softwood cuttings taken during the growing season are more likely to root successfully. The cuttings should be about 6-8 inches long, and the leaves on the lower half should be removed. The cuttings should be dipped into rooting hormone powder before being planted in a well-draining soil mixture. The cuttings should be kept in a moist environment, and misting should be done regularly to keep them hydrated. It takes about 3-4 weeks for the cuttings to root, and once rooted, they can be transplanted into individual pots or directly into the garden.
