I have two species ....P. tripartita.... and P.pedatisecta.
I am wondering if anyone else has experience growing these guys .. I have heard they can be weedy. Is this true?
Do the seed they produce need any cold stratification period in order to germinate ?
How big do they get?
Chris
No experience, but here's some info I got from Bown's _Aroids_:
Height: P. pedatisecta to 12" tall, tripartita to 18".
The seeds are to be sown in a cold frame according to what I read, so that might indicate that they do need to be exposed to moist cold to germinate. Since they're both pretty frost hardy, the seed could be put in the ground where they're situated. But that's just speculation........
There wasn't anything about them being weedy, but that might be a great quality. I guess if they're growing in a really good place, they might colonize well over time, and you'd have tons to sell or give at Halloween. :-)

I have had mine in the ground since the first week of April in a mostly shady spot. They have grown well (thrown out 6 new leaves) but by no means have become weedy
now, if someone had just told me that about the horsetail reed!
Pinellia's specially the species you guys have been talking about are very easy to grow. They are hardy to about zone 4 or so. They do not seem weedy at all for your first year or two but watch out after they start to bloom the seeds are extremely easy and spread fast. After your flowers have seeded next season you will find them all over the place. You can throw seeds around on the ground and expect a good germination next seaon in just about any spot. Once you get about 10 nice size flowering plants look out you will have a ocean of them. I personally like them but give them room to spread in the garden.
thats a great thing to know Brian.. Thanks soo much

If this is the same thing that I have, called 'Green Dragon', I started with 1 that I bought at the Botanical Garden, next thing I knew (2 years) they were everywhere. I pull them up by the handfulls to keep them from choaking out my hellebores. Every time I see a bloom, I pull it off.
They're not the same plant, Linda, but thanks for the headsup about their being like rabbits, too. ;-)
The Pinellias discussed are from China and Japan, the Ariaema dracontium, a US native.
