Hi Vickie,

You didn’t include a picture so I think this is the plant your Mom has.

Sedum spurium tricolor (Stonecrop)

This type of sedum, which is a Succulent PlantLearn the definition of a succulent plant and why they are called a "fat plant.", has small green, pink, and creamy white leaves. It is also called “stonecrop.” In the summer it gets pink  flowers. Sedum is very easy to propagate, just break off  pieces of the stem during the early days of summer and plant them in some soil. It doesn’t even matter if the soil is normal, sandy, or clay. Here’s what it looks like in bloom.
