ordinary caerulea will do the job
alatocaerulea won't. Be very careful re transplanting the alata-could easily kill it.

Yup- caerulea. Get one & use it as a polinator- even better get 2 as they're not self fertile. I have a load of caerulea seeds- I could send you a couple if you want to go that route.

I've been trying to polinate my altocaerulea for years.. Nothing works.

And yes be carefull digging up that alata- keep as much of the rootball intact & undisturbed as possible- Frankly if it were me I'd be afraid so I wish you luck.

Thanks for the answers!

I would appreciate some seeds, Krstofer. Do you want some Incense cuttings in return?

I'll be as careful as I can with the alata. I'd rather leave it where it is, but have learned that a passion vine can out-compete and out-grow any other plant around--except another passion vine. Hopefully, a move to a place where the incense doesn't have a lock will let it grow.
