It seems like you have two aeoniums and a sempervivum. I don’t know where you’re located so I cannot offer much advice. I know they thrive in bright shade as my summers get to be in the triple digits. However, depending on your location they may do well in full sun. The aeoniums will eventually branch out and form tree like clusters and the sempervivum will put out a lot of babies. Both are monocaroic meaning they will die after flowering so be diligent about separating and propagating if you want to keep these for years to come.

I forgot to add, the aeounium is a winter grower (I’m not sure about the semp as they don’t do well for me here) so water in winter cut back on the watering in the summer. If you live in an extremely hot climate then they will appreciate the extra water in summer. Otherwise avoid watering. In my own experience, the aeoniums do seem to love water a lot more than my other succulents.

I agree they're all Aeoniums, & would benefit from corrected soil, faster draining like C&S mix combined w/ Perlite.

In Summer if too hot, these plants will close up their heads, so pls. don't think they're dying, they're just Summer dormant. I didn't find they did well indoors, I believe they're really outdoor plants, sorry.

That first plant looks really nice & healthy!

Thanks! That helps a lot!

You're welcome Jenna, nice that you found it helpful, I'm glad.
