Lavander plant

Hi,
Last week i got a lavander plant from my nursery near our house.
The tree was as small as 1 inch.
The smell of lavander is killing my hearts that i dont want to cut the leaves.
A touch of leaves is giving me a lovely aroma.
I read that lavander is good for mood change.
It helps as a mosquito repellant
Here is my lavander plantand is 3 inches.
I have transfered it to this big planting pot of 2 gallons.
