It could be due to more plant hormones and beneficial microbes. Two root systems= double the good stuff (rooting hormones/good fungi and microbes)?

I'll go with that!

I have heard this before. I listen to a radio garden show and this guy always puts several cutting in one pot and not just to make sure that one takes...he says they take better if there is more than one. I have also heard this from a rose grower who would root roses in a mini green house: a 1 gallon plastic bag.

I have a few pots of bunk mates now :D They are all doing well. (so far!)

In this case, Steven, I would probably say two or more main stems. Some people pot different cultivars together, but only if their watering situations are similar, if I recall correctly.

Also, grouping plants together makes them happy since it raises the humidity around them :).

Brad is right! I will pot up caudata, phuwuanensis, and praetorii together, but wouldn't dare add a pachyclada or pottsii...they'd rot!

You could also do carnosa, pubicalyx, and verticillata together :). Or switch or add obovata to that mixture as well. I wonder of Mathilde and lacunosa would do well together? One that would be pretty is obsura, lacunosa, and cv. Sunrise. Darn my creative side lol.

Brad AKA Moonwolf

Lacunosa typically likes a bit more moisture than cv. Mathilde (which has carnosa section parentage), but it might work!

I thought as much. Carnosa likes it to dry out and serpens (the other parent of cv. Mathilde) likes it more on the wet side if I recall. But anyway, I remember there being a thread about "community pots". I would like to try one with something like Pink Silver, RHP, and Red Buttons.

The mixed pots I have are minibelle and sweetheart (some mystery plant with that name that looks like a carnosa or pubicalyx. NOT kerrii), krimson princess and a krinkle, cumingiana santos x cummingii (whatever that is...) and cinnamomifolia and cinnamomifolia var. purpureofusca. I have a bunch of others growing with two of the same plants in the same pot. Everyone seems comfy and I save on space!

Now if only I knew what would play nice with deykeae I'd give him a room mate, grumpy little thing :(

Thanks for the heads up about the pottsii and pachyclada! So the thick fleshies won't do well together then? Not even in a colder state with low humidity? There goes my plant to pot up my two struggling variegated kerrii's.....

Deykeae and finlaysonii/callistophylla :)

Pachyclada would do well with subquintuplinervis, australis ssp. oramicola, australis rupicola, and sp. IV WMZ.

I can go without watering pachy and the above for a month+ in cooler weather, whereas pottsii, kerrii, and most others need to be watered once every 2 weeks or less (for me/my conditions).

Kerrii would do fine with obovata, diversifolia, excavata, meliflua, treubiana, and fraterna.

This is fun! I could put deykeae in with my finlaysonii but finny is growing great guns at the moment and has grown 10cms and 5 new leaves (after not doing a thing for over 6 months...) and I don't want to upset it. My meliflua would probably strangle any pot mates so that's out. Anything grow well with australis v tenuipes?

Australis 'Lisa', aldrichii, calycina, pottsii, verticillata/pallida/acuta/parasitica/whatever it's name is this year, sp. UT-30 through UT-39, wibergiae, to name a few.

I'd stick with australis 'Lisa' or calycina because their growing habits are similar to that of tenuipes (Lisa is just tenuipes variegated).

Somehow I don't think I'll come across "Lisa" anytime soon down here in what I refer to as " Northern Antarctica" (Tasmania, Australia) :D I've come across a couple of calycina before though. Actually, australs is part of my "lets see if this will survive Winter here" collection. I haven't had it long enough to test.

I have a verticillata (growing happily and has a peduncle!) and an acuta(tanty chucking brat) and they look different. Acuta has smaller, narrower speckled leaves. Just variations of the same species?

We honestly don't know. Without DNA confirmation, we can only guess. I do think verticillata is different from acuta, but parasitica, acuta, and pallida seem to be almost identical in basic characteristics.

My pallida does have smaller leaves than my acutas and parasiticas, though. If I had the $$, I'd pay for the DNA testing myself, just to sort the mess out!

My acuta was a nice full plant when I got it, then started getting yellow leaves. Over a few months I tried watering more, less, more fertiliser, checked roots, gave it less sun, nothing helped. Eventually I got fed up with it, chopped off the yellowing vines and dumped it on the back shelf in "death row" and forgot about it. Rotten thing is happy now and growing new vines... naturally.
