I loved this little guy, and then one time I overwatered and let water sit in the soil. It just immediately rotted completely.

* This plant sits in a west-facing window sill. I water it about every 10 days or so.
I like this plant, it's not one of my favorites, but I like this plant. It is very easy to care for. It just sits there and doesn't bother anyone. It's very unique looking. Because of my set-up, I bottom water it. I am anticipating having to repot it soon seeing that it fills up the entire plastic pot now.

I love this little succulent. The leaves are soft and you’ll know you’re doing something right when the plant opens up a bit. This plant has the capability to produce multiple plants/buds

one of my first succulents and a great one for a beginner, as it’s pretty, easy to care for and grows quickly, you even can see the water inside of the leaves! Mine is named Amelia and is incredibly large now and I love her dearly, but make sure to move away from direct sunlight as once they grow bigger they brown much quicker

My cat knocked it over and it was out of a pot for about 2 weeks and was still perfectly fine once repotted.

was bought from a big box store and had all of its roots tangled in a mesh that made it impossible to grow. It was bought several years ago though and shes still surviving.
