If you can't find anyone that has them you can buy them at Butterfly World. There's about 20-30 seeds per pack if I remember correctly. You can ask if they'll mail them to you.

Here is a link that might be useful: Butterfly World

thanks karyn, you are always so helpful :)
Siam.

I'll probably be placing a passie order with Butterfly World in the next month and can order the seeds for you if you haven't found them. Even if they'll ship to you it would probably cost less for me to mail them. I'll let you know when I'm placing my order. I'm also growing it as a host plant but didn't put it in the yard last summer because it wouldn't have supported a single caterpillar. lol I think it will be big enough to go outside this year.

Thanks karyn, i really appreciate it. Giant swallowtail butterflies visit my garden. I have 1 orange tree, not sure which variety, its big, but i havent seen any caterpillars on it ever! I read that the wild lime is one of their favourites thats why i decided to try it. There are alot of citrus available in trinidad, is there any other type you know of that giant swallowtails prefer?
karyn, have you ever grow the sunflower tree? would you like to try some?

I found this list. Maybe it will help. I still have plenty of Orange Jasmine seeds if you want some. They take a while to germinate but grow pretty fast once up and the flowers smell wonderful. I get several varieties of swallowtails but find it easier to tell most of them apart in the larval stage. Many adults of different varieties look the same to me. I didn't realize I had so many different ones until I had the cats ID'd. I think the Giant Swallowtail cats look like bird poo. The Spicebush looks like poo in the early instars but is beautiful in the 5th instar. I think it's one of the prettiest ones I get in the garden.

I would love to have some of the orange jasmine seeds, thank you so much. Do you have any seeds of Aristolochia vines?
I have some scarlet milkweed and some yellow milkweed plants that i recently started, and they already have a few monarch caterpillars :) im so excited.
Thanks Karyn,
Siam.

I might have some A. fimbriata seeds. I'll take a look. If I have them I'll send them with the orange jasmine.

Thanks so much Karyn :)
