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'.
