Okay...back again. The succulent I found that is closest to looking like yours is Portulaca molokiniensis. I have no personal experience with this plant & have never seen it in person, so I cannot vouch for the veining in the leaves being the same. But...take a look at the links below & see what you think. If/when it blooms, you could confirm. These have stems somewhat like yours (I can't see clearly). http://www.hawaiioirc.org/OIRC-SPECIES-PLANTS/Portulaca-molok-FKStarr.jpg Here is a link that might be useful:

Laura It shouldn't be difficult to separate them - there seems to be lots of space between individual plants. You can behead them - chop off top part of plant (best to use sharp knife), let callous and pot up. You can pot up lower part (leftover trunk with roots) & you could get some new babies sprouting from it. It would be good to improve your potting mix, this one looks pretty peaty (hard to tell from your photo). They would enjoy more gritty mix - much better drainage. There are some skinny & tall plants in the background - are they succulents? Edited to add: here is a thread with very similar question and good photos: beheading echeveria Howard (bikerdoc) is giving excellent advice & photos showing 'leftover' trunks growing new plants.

WOW! Thank you sooooo much robinswfl!!! I looked it up and....there it was!! I searched high n low looking for the correct ID. Found not a thing. You made my day!! :))))))

Sorry I can't ID them for you as I only grow a limited range of succs, and not these. I can say that they are mostly etiolated/stretched out due to lack of light. I'm pretty sure they should all be growing in rosettes close to the soil, not on long stems like those in the purple pot. Your mix could use more perlite than you have already, it apppears to be rather heavy on the peaty component which can lead to root rot if you're watering is more than needed, or if they stay wet for too long being kept outside. Old, already etiolated growths will not revert to 'proper' growths, only the new growth will be tight....if given the correct lighting that is. Gill
