Ceropegia ampliata

This asclepiad has one of the larger ceropegia flowers, about the size of my thumb. I made some cuttings from friend's plant this spring, and now they are starting to flower. The plant barely grows any leaves, which it quickly sheds, leaving the succulent green stem as the only photosynthetic surface. It's amazing that it can summon enough energy from a foot or two of stem to make such a large flower, but all four cuttings are either in flower or in bud right now.

The flower is an insect trap - hairs inside will keep flies there overnight before releasing them covered in pollen the next day. I'll have to dissect one soon, but meanwhile I'm enjoying the very strange flowers from the outside.

A note on the cuttings: the cut ends need to dry out before being plunged into soil, which should be allowed to dry almost completely between waterings. Otherwise, one ends up with melting cuttings, which is what happened the first time I tried this. Standard succulent practice, really, but something to remember.

This particular plant does better than most ceropegias in a moist, tropical lowland greenhouse once it's established.

I do love ceropegias - the flowers grow in such interesting forms.

Comments:
Just amazing.
 
well, it does not seem to do well at all for me - I had it for more than 10 years now and all it does it keep growing those leafless stems then drying out .....
 
That's odd - leafless stems are good - it hardly grows leaves, but the drying out part not so much. I will say that the flowering seems to be seasonally triggered somehow - don't know if it's a light thing or a heat thing or a water thing, but in the greenhouse it's either a few days of very high temperatures, or light... maybe you don't get that where you are?
 
Your plants are truly amazing.
Great, great collection.
