Description
Welwitschia mirabilis (Welwitschiaceae) (price per 5 seeds) An adult welwitschia consists of two leaves, a stem base and roots.That is all! Its two permanent leaves are unique in the plant kingdom.They are the original leaves from when the plant was a seedling, and they just continue to grow and are never shed. They are leathery, broad, strap-shaped and they lie on the ground becoming torn to ribbons and tattered with age. The stem is low, woody, hollowed-out, obconical in shape and sturdy. Sowing : Seed should be sown during the warmer months, spring or summer. In habitat the seeds are dispersed in spring, but have to wait for rain to fall before they germinate. It is best to sow seed into a large, deep (at least 300 mm, preferably more) container or into an open bed where the plant is intended to remain, because the taproot grows quite fast in the initial stages. If using a container, remember to place a layer of gravel or rocks at the bottom to ensure good drainage. The soil must be sandy and well-drained, e.g. 2 parts sand : 1 part loam : 1 part compost (leaf mould) with ample bonemeal, well mixed and sterilized. Moisten the soil thoroughly before sowing. If using a container, sow two or three seeds per container, near the centre. If more than one germinates, it can be transplanted in its first month, or left to form interesting graft complexes with its sibling. If you have an open bed, scatter them evenly over the surface. Place the seed on top of the soil and just cover it with a layer of sand. Water well and keep in a warm sunny situation. It is important to add a mild fungicide, like Captan, to the water during the first year as it will prevent fungal attack. Keep the soil moist until the seeds have germinated. Germination takes 1 to 3 weeks. Locality: Swakopmund. Harvest: January 2022
