Natal Red Top is easily propagated from seed sown in spring or early summer months, in a well-drained medium, preferably in plugs. Seed collected last summer can be kept in a dry environment, until next spring, when it can be sown. Seed germination in full sun occurs within 2 weeks of sowing. Germinated seedlings must be kept moist and be planted out when roots are packed around the plug and can be easily pulled out, without losing much growing medium. Once planted out, seedling establishment is rapid and flowering is modestly in the first season, peaking in the second and third growing season.
