hello. does anyone know about this plant. I googled it and I believe it's a lavender plant.

what kind of care does if require. can it be planted outside? if so where? is it a plant that returns yearly on its own.

basically I know nothing about it and the store i bought it at knew nothing.

let me know if a better photo is needed.

thanks a bunch
