My sister says that she has a hard time propagating plants, but I am convinced she can propagate succulents. Many succulents are very easy to propagate and frequently propagate themselves! I have dozens of new succulent plants all over the yard just because a leaf broke off, and it started anew!
Here's a leaf that broke away from a graptoveria plant:
That leaf then starts to sprout new leaves within 1-2 weeks:
Next the roots form and the original leaf starts to shrivel as it becomes depleted:
The new plant continues to grow:
After a while, you end up with something like this:
This particular plant is years old, but you will have a definite plant within a few months that's charming AND resilient! It'll continue to propagate itself, and the young plants make for a great gift or filling in bare spots in the garden.
