Kevin Are you thinking that mine is not swamp milkweed for some reason? It was labeled as swamp milkweed from a local nursery that I find to be very reliable and it has bloomed and the blooms look just like swamp milkweed images I have looked up online. Just curious since you seemed skeptical. Thanks for the feedback on the size. That's very helpful!

I have rooted tropical milkweed easily by just putting it in water. Have seen roots usually within a week. I am not sure if this helps.

No. I look at this plant every day. It's like other milkweed flowering stems where you have one main stem and then it branches to several stems where the flowers bloom, except instead of flowers, it's seed pods - like 5 seed pods opening at different times on the one main stem. And they have Milkweed Bugs just waiting for that pod to open! The seeds are flat brown (like a flattened dried up black-eyed pea) and attached to a silky white blow-away "parachute"... to help carry them for growing. Each pod holds no less than 50 seeds. Now, the seed pod may start out looking like a teeny tiny cauliflower (if I recall), but it's nothing that produces nectar as there is nothing that comes to it - Monarchs/bees/hummers/flies flutter around my flowering milkweed all day. I will try to get a pic when I can. Monarch Watch was at our local botanical garden last weekend and I talked to a few of the workers and no one could help. Maybe I need to go back to the nursery where they were purchased! And I agree, Orange Butterfly Weed is pretty! I wish I had some!!! The leaves of this one are identical to the Swamp Milkweed (with the light pink flowers).

I have seeds that I'll be more than happy to share with you. I have 2 milkweeds that all they did this year was create seed pods. I picked the seeds off when the pod opened. Let me know if you're interested. I really can't tell you what kind of milkweed it is since I never got to see it bloom, but it's very similar to the swamp milkweed and may even be that. I bought them at a plant nursery last year.
