I bought a two foot plant from a nursery in May and my plant has been blooming now for about 2 weeks with lots of buds waiting to open. It has grown like crazy; I have it in a large pot with a trellis that is definately not large enough! I have fertilized every week or two with 20-20-20; up to now we have had a lot of rainfall so I haven't had to water very often. I was actually quite pleasantly surprised to see it blooming so early as I understood it not to bloom until later in the season. I actually tried to start my own plants from seeds this spring but was not successful. I will definately try again next year.

No, the previous post/title was the mistake. This photo is the white-flowered vine (I already identified the lilac flower). Sorry for the confusion!

Can't be Solandra which has an alternate leaf arrangement. The vine in question has paired (opposite) leaves. Here is a link that might be useful: Solandra

thanks very much for the i.d. wanda. now the mystery is where it came from because i have never heard of it. probably it arrived in a pot with some other plant. min
