Description:
Slender tall plant (2 meters) with mottled snake skin patterned stems. Spathe is purple brown with narrow white stripes the elongated hood tapers to a long thread. Single leaf is divided into 12 or so leaflets that too end with long fine points. Makes dime sized corms in its first year.
Notes:
One of the hardiest and easiest to grow Arisaema. Wonderful in the shade garden. Spathe withers to reveil green berries that ripen to a bright scarlet. Nearly all Arisaema species are gendered, but its interesting to note Arisaema are capable of changing their sex even in mid season. Small plants are usally male until the corm reaches sufficent size thus carbohydrate stores to support seed production then it becomes female! One of the very few plants capable of 'switching'.

Soak seed 24 hours; best if container grown for the first few years; sow thinly at 6 mm deep; stratify 8 weeks but don't let seed freeze; optimum germination temp: 15-22 C; days to germinate: 14-35. Never let seedlings to dry out. Let form bulbs until planting out in final position. Seat plants 10 cm deep. Group plantings look best. Our method: soak seed in Skookum for 48 hours. Sow in baggie with moistened peat moss. Provide 20-25C. Germinates in 10 days. Prick out and transplant.
