Aristolochia tomentosa
Comments (1)Propagation notes, Explorers Garden - Hinkley: fruits of the pipevine remain extremely hard until late autumn when they soften and dehisce the seeds. Seeds will germinate readily after cold stratification" If seed is sown immediately, as soon as it is ripe in the Fall, they may germinate in 1-3 months with no moist chill, but for best results you may want to begin with the chill even if you know your seed to be freshest. You're an 8A? I'm 8B, if mine I would sow now through end of January and place the pots outside for mother nature to provide some fluctuating temps before becoming more consistently warmer....See MoreMamas4boys - Butterfly plant suggestions for zone7b - photo heavy
Comments (1)Hello, Just wanted to butt in and say that I have plenty of seeds for the orange milkweed or butterflyweed, and I have lots of seed pods forming as we speak. I also have many volunteer baby Rue plants that could probably be mailed in a pinch. I haven't checked for seeds of the Rue, because I have so much already growing. Unfortunately, I have yet to see any Giant Swallowtail action, despite having every host plant it is known to frequent. I also have seeds for two other varieties of milkweed, A. incarnata (swamp) and one called "Red" by Seed Saver's Exchange. If you're looking for seeds, try the wintersowing forum--also an excellent way to get multiple plants started inexpensively and very reliably. I could certainly send you a care package to get you started. Let me know. Martha...See MoreAnyone ever grow Aristolochia durior x elegans?
Comments (9)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....See MoreFirst Aristolochia Seed Pods....
