I love Tropical Milkweed but it really is an annual here. Have to mostly grow the old standbys of Milkweed and Butterfly Weed. But hopefully everyone more down south with start growing Asclepias curassavica for the butterflies.

A. curassavica has been one of my favorite plants for a few years now ... I can't imagine not having a few in my garden!

A. curassavica, A. texana (Texas or White Milkweed), Funastrum cynanchoides (Climbing Milkweed) and A. asperula (Antelope Horns) are the milkweed that I grow. I had some Queen butterflies lay eggs on the milkweed this year, some caterpillars even survived to become butterflies. One Monarch caterpillar raised this fall, just pupated today...that will be all for the year, unless more Monarchs come along that want to lay eggs. I had a nice time this week when I went to the dam area and saw the Monarchs on the move there.

I never heard of those different milkweeds. I am glad you were rewarded with so much Monarch action
Josephine,thank you for reminding me that they are not winterhardy. I have one that grow right near my house and I guess it just stays warm enough to live through the winter, so somehow I was thinking it was a perennial

Asclepias curassavica sometimes survives the winter here, but it will die to the ground, then will not be up and growing when the Monarchs return in the spring, that is why it is good to have some ready for them.
Thank you Everyone for the responses, I appreciate it.

I will add the milk weed to my pot moving ritual.
If I had more space and less dogs, I would think about a greenhouse
