Arisaema ringens

Description

“Pet poisonous” – Toxic parts: entire plant esp. roots, leaves The Arisaema Ring's is a cold-growing species first described by Carl Peter Thunberg , and became known as Heinrich Wilhelm Schott . Arisaema ringens are included in the genus Arisaema and the family cold plants . The closest relatives of Arisaema appear to be Pinellia and Typhonium (although the latter as defined in 2004 seems to be paraphyletic, having given rise to Arisaema and other genera). One unusual trait shared by all Arisaema species, and not those of other genera, is the sex change. Arisaema plants are typically male when small, and female or hermaphraditic when large, with a single plant capable of changing sex based on nutrition and genetics, and perhaps changing sex several times during its long life (20 years or more)
