You can order eupatorium fistulosum, which is the native-to-MS very tall type, from Mail Order Natives. I've never seen it for sale locally, but if you're lucky enough to have a native plant nursery near you, you might be able to find it there. Various on-line nurseries carry other types of joe-pye-weed, some shorter than our native type - you can Google it to see which ones carry it presently.
I don't know about passi seeds - you could Google "Passiflora" and see what you come up with.

I ordered passi seeds off ebay for 99 cents. I haven't had any luck getting them to grow yet.

I wish I hadn't thrown dug out my Joe Pyeweed and pitched it. I could have given it to you or someone else, but I was so mad that it didn't attract any butterflies here for two years that I got rid of it. It's funny how flowers at one person's place attracts the butterflies but not at another. I think it's a plant with unusual flowers, but they didn't bloom more than a few weeks and I never saw even one butterfly on the plant. I figured I need the garden space for a plant that the butterflies like. I had bought the plant from a local nursery where I usually go if I'm in a plant buying mood and have some money. I hope you have luck trying to find the things that you want and hopefully they'll do well for you.

The only bad thing about pye weed is it blooms so late and it is such a big plant I dont have enough space for this guy and the blooms are so little.Butterflys do love it but it blooms so late here.I think for the space I like mexican sunflower much more it blooms all summer and into fall here.

Hi everyone, thanks for responding. I've been thinking, and based on your posting I think I will plant something else other than Joe pye weed. I am having a very hard time finding it, and besides, if it is only going to flower for a little while, like angie said, I don't think it is going to be worth it. I am considering Bee Balm (monarda spp), Mexican Sunflowers, or Black Eyed Susans, instead. What do you guys think about these? Do you have any other suggestions? I already have Pentas, Salvias, Lantanas, Golden Dewdrop, Zinnias,and Butterfly Bush. I do prefer perennials. I am just trying to expand my garden.

Thanks ladies!

Mexican sunflowers and Mexican flamevine are the best! They both bloom profusely from about late spring/early summer 'til late fall/early winter, and attract more butterflies for me than anything else, even butterfly bush and lantana.

I bought my Joe Pye Weed at Joshua's a Houston nursery. I've only had mine one season but it didn't seem to be as big of a butterfly attractant as I expected it to be. And the blooms are not very colorful. Greg's Blue Mist Flower, Trailing Lantana montevidensis, moss verbena, mexican flame vine are all favorite nectar plants in my garden. I have a lot of black eyed susan's but they do not tend to attract butterflys. As for passiflora, I recommend you try to attend one of your local plant swaps they post the plant swaps on the Texas Gardening forum under exchanges. The Galveston Plant Swap always has a lot of passiflora plants for exchange.

Do you have a preference on the type of Mexican Sunflowers? I haven't had any luck growing them. Do you grow them from seed?

Do you have any HOST plants in your garden? I'd definitely recommend planting lots of host plants along with the nectar plants. In my garden I have more host plants than nectar because my neighbors have so many nectar plants that I find the butterflies can go and visit them then come back to MY yard to 'live.' ;P Actually, most of my host plants are good nectar plants so they serve a dual purpose.

Like MissSherry, I do so love the Mexican Flame Vine. In fact, this past year I took a few cuttings, stuck 'em in a pot on the opposite side of my Butterfly Sanctuary, and now I've got a lovely growing 'pole' of MFV that just had its first bloom. Even my DH loves the Mexican Flame Vine (and interestingly enough, he was most hesitant when I first brought one home from the nursery..."Sherry, are you SURE about this thing? It doesn't look very attractive and is this something that is going to be ugly or what?" Ha!)

In our yard it is Milkweed, Milkweed, MILKWEED! Gobs of the stuff. Even DH says, "You need to get MORE Milkweed planted, hon." So, sure, having the variety is nice but I guess to each his/her own!

Plant on!

Hi Dena I got most my host plants from you at the galvesten swap I was not very happy with my joe pye weed either its no were as good a draw as the mexican flame vine and it roots so easy in just water I have tones of it too .I might have to try the shorter joe pye weed but its not ganna get the draw the porterweed does,and the bloom time is so short for the space it takes up.

Hi Angie, my Joe Pye Weed is the shorter version. I'll have to look up it's exact name. Do you want to plan to swap Joe Pye weeds at the Galv swap?

Hi Dena love to I would love the short one .
