About this species

Arisaema jacquemontii is a cobra lily belonging to the same genus as jack-in-the-pulpit (A. triphyllum). One unusual trait shared by all Arisaema species, and not those of other genera within the Araceae, is the ability of plants to change sex during their lifetime. Arisaema plants are typically male when small, and female or hermaphroditic when large, with a single plant capable of changing sex depending on its nutrition and genetics, and perhaps changing sex several times during its long life (20 years or more).


Arisaema wightii, A. exile, A. cornutum, A. cylindraceum.
