Out of curiosity, I've propagated several tip cuttings (about 8-10" tall) from A. curassavica because I'm hoping to save the snippings in case the roots don't survive winter. I'm on the edge of hardiness for that species. I've put them in water and they took root very quickly, and have continued to bloom while doing so. This was so easy! I didn't start this until a few weeks ago, so I haven't had time yet to try putting them directly into soil. Assuming I have something left inside or out by spring, I'll definitely try that. These plants are so tall and thin, it would be easy to have a LOT more of them.

Has anyone else tried cuttings/snippings of other species? What method did you use?

THe only thing that I am aware of is that the tropical milkweed spread like crazy from the seeds just falling on the ground here.

If that's possible here, I may have some sprouts too. I've saved some seeds but I've not remembered to check often enough to get even half of them.

Yay! I have done tip cuttings of curassavica. Their stems seem solid unlike local syriaca. Also had them self sow, so I think in your warmer zone you will find some.

Blooming when snipped & now has a lot of roots & continues to look the same. If it stays alive in a windowsill over winter, that's easier to me than seeds.

Phenomenal Tiffany!!!!! I am going to try this next year!

I thought so too. I didn't have any snips of this fail to take root. The ones I brought inside look pretty upset, but are stayin' alive.
