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.

We left this plant behind in our Pennsylvania garden (and wish it well); we don't grow it in Houston. About my plant portraits

Visitors to this page have left the following comments| Deborah K | Aug 28, 2016 | May I please have your info re how/when to gather and how to propagating Arisarma Ringens from a seed head that is still in my garden. At present it is green but very well developed. Thank you, Deborah K
I've not collected seed from this particular one, but with other aroids I've just harvested the round seeds once they colored and dried in the seedhead. You can read about germination in the detail records on this page (basically, germination occurs at room temperature but may take a while). |
