Mums are Perennials and will go dormant (sleep) after the flowers are gone , but will come back . You can plant them in the ground, mulch - and they will come back yr after year. You can research the kind of mums and see when is the right time to plant your mums in your area.

Chrysanthemum and marigold
I suggest you call your local La Quinta store in the garden section and ask them if they have Lavender plants and if they don't ,ask them when do they think they will have some.
