I just bought a Mum from the Walmart garden store. It has purple and yellow flowers---small. Can I plant it outside in a barrel now? I live in southwest Idaho.

Yes, you can go ahead and plant your outdoor autumn planters.
Generally the plants sold at this time of year are a hardy mum cultivator.
With proper care it can be wintered over, but many grow them as a annual fall plant.
Here is a few links with more information.
