Euphorbia is a pretty flower although the plant is full of thorns. It also has latex which one needs to be careful with.
If carefully handled Euphorbia is a beautiful flower and the plant does not demand much to yield results.
We have several of these plants and they are perennial. They only need to be protected from heavy rain.
What is noteworthy is plants emerge from some flowers and they can be planted.
Do you have flowers that give out plants?
