Arisaema thunbergii ssp. urashima / Urashimasou ウラシマソウ

 
Arisaema thunbergii ssp. urashima is a perennial herb inhabiting forest floors in coastal areas or near human settlements, with single compound leaves. Corms form many bulblets underground, which generally results in colonies. Leaves, singles, are radical, emerging from the bases of the plants, comprising 11-17 leaflets, called pedate compound leaves. Pedicles measure 40-50cm in height, which look like stems. From the bases, flower stalks arise, and the tops set spadixes with flowers enveloped with spathes below the leaves. The flowers are dioecious; young strains put male flowers, and complete ones give females. Appendages, black-purple, measure 60cm in length. Bloom time: April-May.
