Looks like 'watch chain', a crassula can't remember variety, lol.

Grassy looking plant is Crassula muscosa.

Get pebbles off, soil is probably peat - plants will grow better in well draining mix.

Is Crassula perfoliata variegata very commonly seen around the USA? It seems pretty rare here in Canada, but you found it at Wal-Mart!

Rina is right about the "grassy stuff" being crassula muscosa. And your crassula perforata seems to be in very good shape. It will grow very tall. You can keep cutting off the steps and sticking them back in soil and they will grow. Everyone is right: pry and scrape off the pebbles, put into a grittier mix that drains well. I buy a number of plants at Walmart (not glued down, but still…Walmart) and most have done very well. I have a Falcata (propeller plant) that did nothing for nearly a year, then grew 6 large pups! My advice is pot them up separately. At minimum, put in C/S soil that has been sieved, with 50% perlite (or even more perlite). Don't water for 5-7 days after repotting.

Kevin,

I've found it at Walmart here in NS before...it is around! I'll keep an eye out for it now..

Ewwmayo, I've honestly never looked since I didn't know what I wanted when I started buying these (my first succulents and cacti) last week. I'm hoping to learn what I'm looking for/at in the months/years to come!

When I removed the crassula muscosa it broke into several smaller sections with dry, almost crispy roots. Should it have all stayed together and connected at the root(s)? And are the crispy roots a sign of doom?

Muscosa grows like a weed - wherever a tiny piece falls, it usually roots. Its kind of plant you get once and don't have to worry about having it allways (not as weedy as some kalanchoe - mother of thousands :).

If my plant gets leggy & dry stems, I just break/cut all dried parts off, stick green stems into a mix, and it keeps growing, looking better. Overall, it will like just a touch more watering - it should be in well draining mix like all other succulents, and good light.

Ok, thank you rina! Crenda I love it! Looking forward to mine thriving & looking like that.

Ok, so on two of the arrangements the glue was all the way down to the roots in some of the plants. Here are the survivors... I had to wash the roots in water to get a lot of the moist soil off, and some of the leaves got knocked off (maybe I can propagate). Should I now let these dry out for a day or two before repotting or go ahead and repot but wait a week or so to water? It's been extremely dry and hot here lately so I'm worried about how that will affect them.

I would just pot them up in dry mix. No need to let the roots dry out in the air. When you re-plant, try to spread the roots of each plant in the mix in different directions.

If it's extremely hot, temporarily put them in a cooler/shadier place.

Emcruz, in your picture of surviving plants, I don't see some from your original picture. Hopefully you didn't toss them. Even with glue on their roots, you can just take cuttings to root.

I actually had two pots of these glued nightmare mixes. Some, I was able to separate, clean, and repot without a problem. Others were more difficult & had roots that made me worry. I did have to cut a couple others apart & am trying to let them dry & callous over before repotting and/or propagating.
