detailed seed-starting info below

Tuberous perennial from east Asia. Its glossy green leaves are divided into three leaflets, and emerge from a speckled purplish spear-shaped sheath in early spring. When they open up, it's almost like an explosion – not only do leaves and stems appear, but the flowers and spathes are also all wrapped inside, ready to expand rapidly. The hooded purple-and-green-striped flowers with glossy purple insides continue to develop through early summer, yielding red berries in mid-late summer. I've had a plant for years, probably a seedling from one of my earliest HPS/MAG seed exchanges, but misidentified it as a different Arisaema all along. Finally, now that I'm growing a fresh batch of A. ringens from seed, and I started looking up its characteristics, things clicked.
