Dan, I hate to be the bearer of bad news, but this one is a terribly invasive pest! I worked in a garden that was overrun with them. Even digging, Round-up treatments, etc didn't put a dent in the population. Morris Arboretum has also had a battle with them. One of the staff mentioned " all parts propagate" which is basically true. Any little piece..... A volunteer and horticulturist connected to Morris gave a program which warned about the Pinellias, but in particular ternata. ( turn from ternata she said, and Try partita, as in tripartita) I would be very careful. Wish I had pictures of the hundreds of these at the garden. It's at least as aggressive as Ranunculus ficaria and I woudn't turn it loose in my garden. http://www.pfaf.org/database/plants.php?Pinellia+ternata quoted from the above site: Plants produce bulbils in their leaf axils and when growing in suitable conditions can become invasive[188, 238]. The plants can be naturalized in woodland[1]. See map below to view where naturalized. Cute but incredibly invasive! I love my Arisaema ringens, sikokianum, candidissimum, kiusianum, etc. but none of them are invasive or have stem bulbils! Carol Here is a link that might be useful: Pinellia ternata

No problem Dan, I should have also mentioned how spectacular your plants look! The galeatum pic is great too. Hope mine looks like that ;o). Still waiting for it to show. Candidissimum and grifithii are just popping up now with all this hot weather after a long cool spring. Soil temps must have stayed pretty cool this year. Everything is coming up in spurts and in a strange order. Urashima and engleri were in mid May, sikokianum and a Chen Yi oddball flowered around 6/1. Dracunculus v. has flowered but no Alocasias showing at all. About 1/2 my Amorphs have broken dormancy the other 1/2 are just sitting there. Strange. Been a weird spring so I'm sure the galeatum will be coming soon. Keep the pics coming!

Here's my update. Arisaema triphyllum seeds began turning red in late August. Both the foliage and the fruit stalk turned yellow, collapsed to the ground, and eventually disappeared. But the bright red fruit still sits on the ground undisturbed. Arisaema sikokianum seeds remain green and plump. The foliage has collapsed, but the fruit stalk remains upright. Arisaema flavum seeds began turning red in late August and the plant collapsed to the ground. The ripe red fruits were eaten by ants and by a Harvestman (Daddy Long Legs). After a few days, all that remained were the seeds. Tom

This storage issue has been researched. Most seeds will last a year or two in the fridge, but much, much longer in the freezer. I store a lot of different kinds of seed in the freezer at 0 degrees F. Lily seeds are still viable after 25-30 years. Amazingly, even tiny dust-like seeds will still grow after 15 years. There are a couple of requirements: 1) the seed has to be DRY when you freeze it. Some seeds can't be dried (oaks, maples, some tropicals, etc.). I know that some Arisaema can be dried (amurense and candidissimum), but I can't make sweeping guarantees. It would be worth an experiment. I dry lily seeds by placing them in an open container and exposing them to indoor temperatures for a few weeks. 2) the seed has to be stored in an airtight container in the freezer. I do not recommend the use of a dessicant. 3) when you take the seed out of the freezer, keep it in its airtight container until it is at room temperature. That way moisture won't condense on the seed.
