Aristea ecklonii is best propagated by seeds which are produced abundantly, as well as by division of the rooted clumps. Clumps are divided in autumn and should be watered immediately afterwards. Sow seeds onto a good soil-based compost. Cover seeds with fine grit or compost approximately as thickly as their own size. Germination is best achieved at 15-20°C. Although the seeds of Aristea ecklonii may be sown at any time, they wait for the spring before emerging.

Aristeas are not easily cultivated. Therefore, if cultivated in the garden, the soil should be humus-rich, with plenty of moisture and full sun. Lack of this may result in non-flowering of the plant. Aristea ecklonii can withstand temperatures down to 12°C. However, they need fire to stimulate flowering and produce more flowers in the spring following a fire.
