Mark,

Mohlenbrock's Guide to the Vascular Flora of Illinois lists "Morus rubra" 
as being the lone native mulberry in Illinois. It is short, <8', with 
deep-lobed and pointy leaves, small fruit, growing in shady woods or 
forest edge.

M. alba and M. nigra are imports. Illinois Everbearing thrives in Illinois 
soils, provided drainage and sun. Drainage might be your issue. In 
Illinois we risk drowning our fruit trees if we don't plan drainage ahead 
of time.
