Propagation of Arisaema ringens:

Seed - best sown as soon as it is ripe in a shady position in a cold frame.

Germination usually takes place in 1 - 6 months at 15C. When large enough to handle, prick the seedlings out into individual pots and grow them on in light shade in the greenhouse for at least a coupe of years until the corms are more than 20mm in diameter. Plant out into their permanent positions whilst they are dormant. Division of tubers when the plant dies down in late summer.
