Thank you very much rosemariero! Very quick answer :)

After some more research I believe the first one to be an Aichryson laxum, however it does have a tighter rosette.

Claire, succulents do not really work in a terrarium setting. Succulent terrariums are fashionable now, but with no drainage, and higher humidity, they will eventually lead to the demise of the plants.

Thank you for your concern Christopher. The "terrarium" is more of a large bowl, and has an open top. I plan to mist sparingly only the roots of the plants about every one to two weeks. I also made sure to use soil specifically for succulents and there is a good two-inch layer of pebbles at the bottom of the glass bowl to help with drainage.

'Soil specifically for succulents' (I am assuming it's bought as such, not mixed by you), may not be good enough in the long run. It usually contains too much peat and water-retentive. You may have found something different - but this is what comes out of bag most likely. It may also attract bugs, mainly annoying fungus gnats.

Pebbles at the bottom will keep water below another substrate (in your case - succulent soil) - if it drains well. But if the roots reach it, they may get too much. Sitting water also stagnates and there could be an unpleasant odor. This is worst case scenario - I am just pointing out what is usually forgotten and 'complicates' care of the plants.

Is there some kind of barrier between the rocks and soil? If not, soil will eventually find it's way down between the pebbles and they become really 'good-for-nothing'.

Of course, it is your plant-planting. They look really good most of the times, but long term could be little different. I don't want to spend time with so many extra take 'care of things' that could be easily eliminated at the potting time. JMO.

Sempervivums grow best outdoors, they are very hardy. They will grow indoors, but may not look that great. They like lots of sun and appreciate some cool weather (wintertime).

Thanks for the response Rina! I made this terrarium mainly for keeping in my college dorm (need some green to keep me happy lol), so I will keep in mind that if things aren't working out I will move them to separate pots and keep them at home :)
