Desert Marigold is well-behaved; drought and extreme heat tolerant. A stand of desert marigold will self-sow in favorable conditions. The seedling rosettes require a period of cold dormancy to set buds. Avoid moist soils which can cause root rot. Propagation: Sow untreated seeds 1/4” deep in the fall in mild areas, winter in colder regions. Spring sown seeds need a moist chilling period.
