Hi. The botanical name for this vine is Beaumontia grandiflora.

I am waiting for mine to bloom - it's still small, and will need to grow a couple of more years before doing so - they are slow-growing in my area. Good luck finding one - they appear to be a lovely vine!

thank you for your input...I hope someone has some seeds and/or starts...

I did a GW member-search and found four folks who have either seeds or cuttings to trade.
