Copiapoa laui is a miniature, clustering copiapoa, with mall stems of about 1 cm and offset to make big mats that are flat to the ground in habitat but form mounds in cultivation and it is difficult to walk without stepping on the heads. C. laui is the smallest species in the genus, this was only discovered in the 1970s and was thought at first to be a species of eriosyce.

The seeds can be sown in pots of fine, well-drained sandy soil, any time during the spring when temperatures are warm. Cover the seeds with a fine layer of grit and water from below with a fungicide to prevent damping off. For the 1-2 weeks cover the pots with a sheet of glass/clear perspex to keep the humidity levels high. Remove the glass and replace it with light shade-cloth and mist once or twice a day for the next two weeks after which most seeds should have germinated. From then on mistings can be reduced to every second and then every third day as the little plants grow. The seedlings should not be disturbed until they are well rooted after which they can be planted separately in small pots. Sometimes it is grafted to avoid root rot problems as plants grafted on an hardy stock are easy to grow and no special skill is required.
