Ceropegia sandersonii - shooting its parachutes now !

I have always loved succulents and I always gave a plus to one I could manage from seeds to bloom. And if the bloom is also "weird" ... the better!
I am not sure when I saw this plant/flower on the Internet, and I forgot where I got the seeds.
I think it was from someone in South Africa. (THANK YOU!)
Anyway, the germination was quite successful, I offered most of the seedlings to friends, on other gardening forums, etc.
Now I've got a couple here in the apartment and a smaller one  at the office.
Here's the ... parachutes. I LOVE them!
