I WSed these last year; in late Jan, in a flat which might be the reason I only had two seeds germinate; not very many seeds in pack. I put them in the ground in Sept.
Placing seed orders IS a losing battle! Shirley!

In the past, I have grow Dutchman's Pipe from seed with excellent results. This week I WS'd some seeds. If someone in the know chimes in we will both learn from their winter sowing experience.

How much sun have you all grown it in?

I am hoping to grow it in mostly shade under some tree canopy.

Do they grow very fast the first year?

Shirley and meadows, did you order your seeds last year? If so where? I can only find a few places which sell the seed. Thanks!

Weebay - I planted mine where they are going to get about 4 hours of sun, mainly because it was the only area big enough for a large vine plant, and I think these plants get big. Mine were about 8" tall when I planted them. I bought the seeds at EasyWildFlowers.com, in Missouri. Really a nice guy to deal with, answered all questions promptly. BTW, the tomentosa is the right one for the pipevine swallowtail, so you are already on the right track!! Shirley!

Weebay, I ws'd A. tomentosa 3 years ago, with great success. Soaked in hot water for 24 hours; sowed on February 20th; sprouted May 14th. I got between 5-10 sprouts, and potted up about 5. Well, I never figured out where to plant them, and so they are still in pots! Unfortunately 3 have died off with only 2 healthy plants left in 1 gallon pots. They probably all would have survived if they had been planted in the ground or potted up to larger containers sooner. But, winter-sowing makes starting stuff from seed so easy, that I have this problem with sprouting vines, shrubs and trees, and not knowing where to plant them!

Supposedly, A. tomentosa and A. macrophylla are the only 2 pipevine species that will be hardy in our colder zones. They grow well in partial shade. Aristolochia is a host plant for the Pipevine Swallowtail, which I have never seen around here, but may be resident in your area.

I ordered the seed from Easywildflowers.com and they still sell it. Very nice guy runs that company, generous quantities, great germination, and I shared many of the extra seeds in SASBEs. Still have some left, but not sure if they are still viable?? Somewhere I read these lose viability quickly; however I am meticulous about storing seeds, so it wouldn't surprise me if they sprouted fine.

Weebay, I was given the seeds which I planted in partial shade. I have extra seeds if you contact me.

terrene,
I would love to take a chance on some seeds if you have some to give away. I never got around to adding the special butterfly plant seeds I wanted to my seed lists for trades, so have to scurry now to get them. I'll send you an email.

Bev

Great sounds like a good one to WS!
Terrene, completely understandable! it's great that some have made it through the years in pots.

meadows, thanks for the offer I'll email you!

I don't know if the pipevine swallowtail is supposed to be in my area, (southwest Ohio), but I'd love to see it. It looks beautiful.

Bev2009, just checked the seeds in the fridge, there are at least 50 seeds left and you are welcome to try some, so send me an email!

Yes Weebay, I am impressed at the hardiness of the 2 plants that have survived. They have survived 2 winters in small pots in my pot ghetto (which gets sheltered by bags of leaves and a mulch of leaves). This winter I sunk them into the ground with some other vines and my 2 baby Dogwood trees. Since I don't really have a place to grow them here, I am thinking about planting them on a nice trellis in the garden at a local school, if they're interested.

See link below, apparently A. tomentosa is native to your area. I think the Pipevine Swallowtail is too!

Here is a link that might be useful: NABA - Aristolochia tomentosa

I winter sowed these this year (actually, back in November), first time trying to grow them. I got the seeds from the same source as the rest of you, from Easyliving. There were more seeds in the packet than I could plant, more than what was said to contain, so I'm storing the extras in the fridge for back-ups in case the ones I sowed fail. Watch, and every one will sprout and I'll have pipevine up the wazoo!

Karen

terrene, I emailed you yesterday. If you didn't get it, could you email me?

Thanks

Hi Bev, I didn't get your email, and then checked your member page and you don't have an option to send you an email? Please turn that option on, or you could try emailing me again. There's been some issues since the login problems, but I've received a couple emails from GW recently, so it should be working.

i just ordered some of these and got some in trade and was having the same questions. the pack said to pour boiling water over them. has anyone done that?

Terrene,

Thanks for the heads up. I updated my email capabilities and sent you another email. I also remember to check the box to send myself a copy of the email and this will give me your email address I can use to follow up in case you don't receive the GW email.

Bev
