Perhaps the best Australian foliage plant Alocasia macrorrhizos is found in Northern Queensland and grows also in South east Asia.
Two species with similar characteristics are found, Alocasia macrorrhizos var brisbanensis and A. macrorrhizos. We treat them the same way.
The leaves are a bright green, large to around 1 metre in height and are nicely textured as well.
This is naturally a clump forming plant, the leaves are held upright and it makes a great understory plant.
Although this a tropical plant it will grow well in more temperate climates as long as it is in a frost free warm position with part shade. It makes an excellent choice for a fernery or shade house where it can be grown as a major feature.
