People always ask what is better- Food or cover?  Have both.  Plant these fruit bearing trees in areas you want to create cover while also providing food!
These late dropping crab apples are deer candy.  These will produce a shrub like tree up to 14' feet tall that will not only produce cover, but a higly disirebale food source.  These are known for being invisible as the deer eat them before you can see them the next day.   These are 16" on average as one year old shrubs.   In limited supply.
