Maybe check your local box stores? Also maybe seach by its botanical name: Cissus & where to buy it.

Yes, just keep checking wherever you normally find plants, and one should eventually turn up.

They recently had a couple at a grocery store near me in 6" baskets for $12.50.

I had given mine away when we moved years back, and was kind of wanting one again, but I thought $12.50 was a bit high, because this is a relatively 'common' plant.

Like to find this plant, had one years ago it was beautiful.
It grew so big.

Diana..I've bought from this seller on Ebay several times the last three years..His plants are healthy, and very affordable.
