This offering is 1 large blooming size (to the left of the picture), and 1 smaller near flowering size (to the right of the picture) tuber divisions of my stock plants, in 2" rose pots, ready for planting. With proper culture expect plants to flower in season.
This species is native to China (south-central, Hainan Island, Manchuria, north-central, southeast), Korea, Japan, Nansei-shoto Islands (Ryukyu Islands), and Taiwan. The genus Pinellia is closely related to Arisaema and like the temperate 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 6” – 9” tall. Mature plants sometimes reach 18” tall. Each tuber produces a 2 – 5 “leaves”. Each “leaf” consists of 3 rounded to teardrop shaped leaflets. The plant alone is very ornamental. Plants usually produce small “intercalary tubers” at the base of the petiole (leaf stem) and the center of the leaflets. These can be removed when the leaf goes dormant an planted like tubers produced from division. The inflorescence is produced separately from the leaves. The inflorescence is 6” – 12” tall. The inflorescence is single flowered and the flower opens as the leaves begin to unfurl or prior to the leaves emerging, giving a good view of the flower. The “flower” is actually a modified inflorescence that consists of the spathe (outer ornamental part) and the spadix (internal sexual bits). The spathe is 2½” – 3” tall and encloses the base of the elongated spadix. The spadix is 3½” – 4½” long and extends above and through the apex of the spathe. Spathes are solid green with the rim of the opening dark purple. The spadix is green with a purple base within the spathe.
