Collect seed when they have turned black and clean off any parts of the flower head remaining. Sow the seed in autumn (April to May), when day and night temperatures fluctuate. In autumn, the day temperatures can be between 20 and 24ºC, whereas the night temperatures are between 4 and 10ºC. This temperature fluctuation provides for optimum germination for many fynbos plant species. 

Fill a seed tray or a container with holes punctured at the base to allow for drainage, with a mixture of composted bark and coarse river sand. Once the medium has been levelled out, sow the seeds on the soil surface. Seeds germinate well when treated with Fynbos Smoke Plus Seed Primer. Cover the seeds with a thin layer of medium and water with a fine rose, keeping the medium damp, but not wet. Place the trays in a slightly shaded and warm area. Seeds can germinate anywhere between 6–8 weeks. 

Once the seedlings have grown enough, plant them out into the garden in a sunny spot that is well drained. These plants grow naturally with other Fynbos plants and grow in clay or in sandy, acidic, well-drained soils. Lanaria lanata could do well in a rockery, planted alongside Erica rhopalantha, Watsonia borbonica, Aristea capitata or even low-growing restios, such as Hypodiscus aristatus and Elegia filacea.
