Arisaema tortuosum 'Strain #2'

[USDA zone 5a – 9b]


I hope to have these available autumn 2023. These are seed grown. While fast to flower from seed, these have proven slow to proliferate.

This seed raised strain has stems (petioles) that are mottled and striated green. The interior of the spathe is also a lighter yellow-green than the exterior.


A member of section Tortuosum. This species is native to Pakistan, Bhutan, Nepal, northern India (Assam, eastern Himalaya, and western Himalaya), Myanmar, and China (Sichuan, Xizang, Yunnan). This species as with our native Jack-in-the-Pulpit, and most Arisaema species are seasonally dormant. Plants sprout from a subterranean corm or tuber in the same fashion as the spring Crocus. Plants of this species grow 20” - 36” tall. Each tuber produces a single stem that terminates with 2 – 3 “leaves”. Each leaf is pedate (2-lobed with the two lobes also lobed). Each “leaf” consists of 7 – 17 smaller oblong leaflets. The plant alone is very ornamental. The inflorescence is produced from the apex of the leafy stem. The inflorescence is produced from the apex of the leafy stem. The inflorescences is 8” – 18” taller that the leaves. The inflorescence is single flowered and the “flower” opens as the leaves begin to unfurl giving a good view of the flower. The flower is 5½” –8½” tall. The “flower” is actually a modified inflorescence that consists of the spathe (outer ornamental part) and the spadix (internal sexual bits). In this species the spathe is 4” – 6” long and green and glaucous (gray-bluish). The apex (lid) is green and glaucous (gray-bluish). The spadix is 4” – 8” long, about ¼” – ½” thick at the base and tapering to a point. The spadix apex emerges upward out of the spathe in a sigmoidal shape.
