Would love to trade for fresh seed of this native vine. I have a number of native Clematis species seed to trade for it. I also have other seeds. Thank you Carol

Hi Sherry and Sandy, Thanks for your comments. I hesitated somewhat posting on this forum as I had read that A. gigantea (and I believe A. elegans) are toxic to some butterfly larvae. However, I assumed that there would be people with considerable experience growing Aristolochias on this forum. The nature of the toxicity is not clear to me, nor is it clear whether a hybrid would share that problem. Is it even known whether the "toxicity" is due to a poisonous substance or substances, or whether the plants are "poisonous" simply because they lack some molecule(s) necessary for the caterpillars' survival? Regardless, I assumed that on a forum like this there would be a number of people who started growing Aristolochias for the butterflies, but then fell in love with the genus for the plants themselves. I know that is true of many who grow Passifloras. I'm not familiar with the debates over the naming of A. durior and A. macrophylla. For some reason I had thought they were synonyms. I have a friend who used to be involved in vine propagation at UCBG and I'm hoping to get his thoughts as to whether the parent could have been A. gigantea. I'm sure there are cases where the flowers of a hybrid are larger than either parent, but (particularly in the absence of polyploidy) I would expect they are rare. An 8 inch flower (assuming the description is correct) is a pretty dramatic increase in size. The white flecks on the leaves are also highly suspicious. Again, my impression is that those are diagnostic of A. gigantea, and never found in A. durior/macrophylla or A. elegans. The white "flecks" are odd enough that many people think their A. gigantea is diseased the first time they notice them. My interest is in the ornamental aspect of the plant, as well as its adaptability. I've grown other Aristolochias--A. gigantea, trilobata/macroura, elegans, and fimbriata. I've offered both unrooted and rooted cuttings of A. gigantea for postage in the past, and at the moment I have rooted cuttings of A. trilobata/macroura that I will need to find homes for. What intrigues me about this particular hybrid is the possibility that it could resemble one of the tropical species in terms of large and dramatic flowers, yet have unusual hardiness. The hardiness is not an issue for me, but it would be for people living in most of the rest of the country. I would guess that there would be people interested in growing such a hybrid outside if it were possible in their climate. Passiflora incarnata is an example of a plant whose hybrids differ in their hardiness. Passiflora 'Incense' (P. incarnata x cincinnata) is one that is reasonably hardy for many people (typically given as zone 7, I think, sometimes even zone 6). Others are much less hardy. In that case the origin of the P. incarnata parent may be one factor, as strains from more Northern regions are not nearly as hardy as those from the Deep South. The bottom line is that for either P. incarnata hybrids or for Aristolochia durior x elegans, the hardiness of the hybrid can't be easily predicted. It needs to be tested. But yes, for those whose sole focus is attracting butterflies, the issue of toxicity is probably more important than hardiness. By the way, I think the Yahoo Aristolochia group has essentially died, with almost no posts in the last year or two.

Hi aristolo, Perhaps I should have followed up on this. This hybrid has been since discussed on the Aristolochia forum on Facebook, as well as privately: https://www.facebook.com/groups/aristolochia For actual posts, this might work: https://www.facebook.com/groups/aristolochia/search/?query=durior%20x%20elegans The thinking and conclusions are essentially identical to yours. I'll post a new photo since my plant bloomed a couple times as well. It seems highly likely that it is some hybrid of A. gigantea and A. elegans. There already seem to be a number of such hybrids out there for sale, typically assigned to one species or another. For example, the plant sold by Suncrest (wholesale) as A. elegans has flowers that are too large for that species, white spots on the leaves, etc. (I have pictures). More interesting is the suggestion (discussed in detail on the Facebook group) that there are really two species: the huge (14 inch flowers) Aristolochia gigantea brasiliensis and the small Aristolochia elegans. The hybrids between them appear to include the plants typically referred to as A. gigantea. Therefore, if the UCBG plant is in fact A. gigantea x A. elegans (or the reverse) that could make it (A. gigantea brasiliensis x A. elegans) x A. elegans. In other words, it would be 3/4 A. elegans and 1/4 A. gigantea brasiliensis. If you are still interested in trying the UCBG plant I can give you something at some point. I have a couple rooted, but was planning on giving one or two of them to people. I also started new cuttings about a week ago. UCBG is still selling bigger plants, with the name unchanged.
