Scientific nameWatsonia marginata is a very pretty plant, with attractive foliage and gorgeous spikes of cup-shaped pink or white flowers. It is easily distinguished from other species of Watsonia by both by its leaves and its flowers.
Propagation is by seed or division of offsets. Seed is sown in autumn, from April until June, thinly, in deep (min. 10 cm) seed trays, to allow for root development. The soil medium should be well-drained, a recommended mix being 2 parts sand : 2 parts compost : 1 part loam or equal parts sand and compost, and the seeds should be planted 3 - 4 mm deep, covered with clean sand and kept moist and lightly shaded. It is also advisable to protect them from rain during this period. Seed germinates readily within 3 to 4 weeks. Watering should be reduced towards the end of the growing season and withheld completely when they are dormant.
The young corms should be lifted at the end of their first season and stored in dry peat in a cool, dry place to prevent rotting, then replanted in March at a depth of one-and-a-half times their size, and spaced 3 cm apart in order to allow sufficient space for the development of the corms. The young plants should flower in their third season. When the corms are being lifted for replanting every 3 to 5 years, the corm clusters can be broken apart and replanted. This should be done during the dormant period (December to April) with replanting done in autumn (March to April).
