Well, I have one but not sure I am doing things alright. I keep it in my greenhouse because it's more humid atmosphere and no direct sun. It gets some good water in the growing season, much less in winter with a short dry spell of ~4-8 weeks. In the summer it's watered via a mist system so the whole plant gets a little shower. Does not like cold temp. My GH only occasionally goes below 8-10C at night in winter and when it does it's for no longer than 6-8 hours, For very frosty night, I place it in a small incubator heated with heatmats overnight. Seems to do ok so far under these conditions. Growing a very windy long leafy stem. Hopefully some bloom in the near future.

Imagine it will depend in part on where you live. I do not have sandersonii but do have one which looks very similar vegetatively. It gets full sun from 8am-2pm during the summer with quite a bit of water. In winter, it sits in a SE window and only gets an occasional watering (trying to avoid etiolation).

What about soil? Something between orchid and cactus soil?

I grew this for a few years, it didn't do much for me. I also grow Hoyas & had this w/ them in my west windows w/ them. They did nothing special except grow gnarly knobs at their joints. I shared some w/Denise in Omaha (of Hoya forum) & she has a greenhouse. I recall her saying her C. sandersonii dropped most of its leaves. Don't recall what I did w/ mine, likely gave it away after some years of uneventful growth.

I believe these are grown in strong, direct sun. My friend Sage of the Ceropegia Journal grew his to blooming out in full sun (IIRC) in Staten Island, NY.

I used my homemade C&S mix w/ pumice.

Ceropegia grow under trees and bushes in habitat and dislike strong, direct sun and appreciate regular watering but in a well-draining organic mix. I don't grow Hoya but I have seen Hoyas thriving under trees in my climate so I would think so. Don't let them get too cold in winter.

I just got a small sandersonii cutting that has rooted in c&s mix and made leaves I keep it like gasteria and cissus quadrangularis.

So, semi shade, watering frequent for most of the year, draining and organic?

I can do that at least....

to be fair niksouthafrica, im fairly new to hoyas myself anyway. Started mine from a cutting about 10 months ago.

Sounds about right. Don't water them when it is cold, they are from summer rainfall areas

Theyll be indoors at all time, and i will be keeping them somewhat dry , come winter.

Btw, id also like to know what kind of secondary support structure should i add, to complement the one already in the pot?

Show us what is in the pot?

A metalic half ring like structure

My Ceropegia cf radicans ssp smithii (again, though, not a sandersonii) never bloomed indoors. This past summer, when placed on my SE unshaded balcony where it received full sun from 8am to 2pm, it bloomed its head off. My balcony gets hot enough to blister one's tender tootsies. However, I live in z6 where even our summer sun is weaker than that of those of you closer to the equator.

Now my Ceropegia linearis var debilis, on the other hand, gets reddish leaves just sitting in my SE window. I have little doubt that if placed on my balcony in the summer it would likely fry.

As far as support structure, you could buy or make a trellis to fit in the pot, or let it cascade.

My Sandersonii is growing and blooming like crazy. It doesn't care the -5°C for few hours. Even more blooming after that! :) I keep it on south facing window with dry warm air from the radiator on one side on the pot and cold temperature from the window on the other side on the pot. Looks like it loves it! I'd say it's the easiest plant I ever had...

I just got one about a month and a half ago. Off of EBay ,from Calif. Cost me $18 and $8 shipping, for a very small 'plant'. It has a few leaves on it and a growing tip.

I guess thats not bad for early March. I hope its dormancy is done. Potted it into a 4in pot with very very fast draining cactus soil, in a south facing window. Might put it outside in a bit. I assume it likes heat and lots of very bright light or even morning direct sun???

Dont know about you, mine made lots of branch buds.

I also got c.woodii.....

Pooh,

What do you mean by 'its dormancy' pls? When I grew it, it grew year long, no dormancy.

Could you pls put zone/location on your Profile? You're in FLA right?

Ceropegia, in general, seem to be "opportunistic growers" .... growing whenever and for as long as conditions are conducive to growth. So in your climate, Pooh, it will likely grow year round.

Karen. I was told and read that 'Sandersonii' went dormant in winter. I am in south Fla zone 10-11?? I got mien from Calif. it came with a growing tip and still has the few leaves it came with,and is growing a tiny bit. but I was told it went 'dead/dormant' till spring. but I assume since it is so hot and sunny here and Calif, it never goes dormant???

Stefan C. Woodii, is such an easy grower, it isnt grown for its blooms, it is grown for its foliage. To me it is almost a 'weed', i grow it and it blooms all the time. This one is suppose to be very hard to get to bloom. And I want that bloom:)

I think they do go dormant even in CA. But going dormant for these does not mean they loose their leaves and go brown. They stay green with leaves on, they just stop growing during which time they don't want water. The warmer the region the shorter the dormancy.

I'd agree with what Alain said
