Formally described to science in 2012, Typhonium rhizomatosum is an easily grown and small species that produces a deep maroon inflorescence and long rhizomatous offsets from the main tuber. This form is from Cambodia and has a slightly greener inflorescence than the more typical form.
Grow in a well drained compost mix. This appears to be a relatively easy species. It is essential that the tubers are kept in their compost whilst dormant in order to prevent desiccation. Keep virtually dry during this period.
Nearly all Typhonium are small plants, and this is no exception. Plants reach around 15cm in height.
These tubers are not yet flowering sized, but are in fact rhizomes with a young tuber attached at the end. Under good conditions, I would imagine one further year before flowering.
