Hello All--
Can anyone help me find a sandpaper vine? Here is a link about it:

I would appreciate any help on finding this vine.
Thanks, CB

I bought one from AlmostEdenPlants.com this spring

Thank you Carena for the info. :)

sorry I didn't post more, I was in a big hurry, as usual! my plant didn't do much this year, just sat there, I kept expecting it to die, but then a few weeks ago, it finally decided to grow a few new leaves. it's not big enough to take a cutting for you yet, maybe next year if you don't have one by then. :)

I understand and I wouldn't want you to take cuttings of it till it is growing well for you. I thank you for offering to help me out when you vine does get bigger. That is very kind of you. I know you were excited when it put on some new leaves---I always get tickled when I see my plants showing new growth. I hope your vine keeps doing well---send me some pics when it blooms. :)
