Care tips
It prefers full sun to partial shade and well-drained soils, although it tolerates a wide range of soil types. Watering should be moderate, allowing the top layer of the substrate to dry out between waterings, and more frequent during dry periods. It is important to avoid waterlogging, as its tuberous roots are susceptible to rot. A common mistake is to underestimate its spreading capacity; ensure it has enough space or control its growth if you do not want it to spread.
