I planted some crabapples and Granny Smith apples for the fall and winter months. Also planted some Wolf River apples for the summer months. Any apple variety will do, but if you want them to continually visit your spread get a few different varieties that ripen at different times of the year. That way there will always be some on the ground.
You should plant them in the early spring or late fall for the best results.
Here's about as good as info as I could find on apple maturity dates:
