While I am uncertain as to the ID of your plant, there are other people here with more experience that can tell you for sure what it is. However, I agree with Rosemarieo -- that your plant is a Kalanchoe synsepala variety. I would guess the plant is too wet, and likely in a very sunny window; perhaps one receiving direct sun. First, repot the plant into a well draining soil, such as Miracle Gro Catcus mix, and make sure your pot has a drainage hole. Before you place the plant into the new pot/soil, add some stones or potsherds on the bottom to increase drainability. Place the plant into its new home, then firm the soil around it. Drench the plant, but then let it dry out 1-2 inches down into the soil BEFORE you give it any more water. You don't want the soil to ever be soggy, and the plant shouldn't sit in standing water -- this will cause root rot. My next suggestion would be to move it to a position about 5 or 6 feet away from the window where it is currently situated (I'm guessing here). Too much direct sun can actually burn the leaves -- sunburn or scorch marks look a lot like the brownish spots on your plant. Lastly, to keep your plant's appearance up, you might consider cutting off some of the more affected leaves, but this is your to preference! Good luck!

Thank you so much for the reply! I will look that up! :) I'm embarrassed to say, I've been staring at them for two days and still have no idea if those are flower stalks or what. Ha. I tried looking up the difference to see if I could figure out what was in store for them, but ended up lost in a sea of Google. :)

Echeveria, unsure of cultivar though. Maybe someone with a better eye will pop along to offer additional help. I think the flowers are used to identify, if I remember correctly, so you're in luck!!!

Hi Gina, no apologies needed:-) people her will chime in on the IDs, it's not a pain at all, and the list is a little less active because it's JUNE, yay, we are all out in the dirt:-) if you don't get a response soon, try this: repost your photos with numbers and just a short request for ID's. That makes it easier for folks to answer. usually you'll get several responses, with each person just IDing a couple plants, rather than one person doing it all. The numbers help make it easier for several folks to each focus on what they know best.
