I'm still pretty new to succulents so someone else my have a more definite answer for you but I'm fairly certain the first is Crassula convoluta (gollum jade). The second is Crassula as well, the species may be lactea.

Sometimes I can't help but rescue a poor plant or two from the big box stores too!

thank you so much!! I'm new as well, and I was worried that the jades leaves were damaged, but I see that they're supposed to be curled like that, and I can't wait for both of them to fill out a little more! I can't help myself, when I walk into stores like lowes/Walmart etc, I've just got to rescue a few!

Nice little jades. It looks like the soil may be a tad too wet,what soil are you using if I may ask?

Im not good with tge scientific names, but I believe your second one 8s commonly called a elephant bush. Googling this should give you the scientific name

Second is Portulacaria afra I believe.

mr. white, I'm using a mixture of sand and regular potting soil, it's worked really well with my other succulents. I'll let these guys sit for a while without watering them, jades get root rot pretty easily don't they? I hope these guys are okay..

Looks like a gollum jade and elephant bush to me. Typically, sand makes potting soil far too water-retentive for succulents. These two particular plants tend to tolerate poor soil conditions, but I'd add in a good bit of perlite to lighten it up if you want to see them thrive.

I keep mine in a 50\50 cs,perlite mix and they are doing well,except a lighting issue, also have a kalanchoe in straight cactus soil and is one of the best looking plants in the house but has to be watered carefully. I'm still learning so I prob shouldn't be offering advice, but when I'm wrong I'll be corrected multiple times which is how I'll continue to learn and that's never a bad thing..enjoy your new plants!!!
