When to plant palm tree seeds?
 

I brought back from CA here to IL some 7/8 diameter palm tree seeds,
like miniature coconuts. They had fallen from the seed pod clusters
and were laying on the ground/sidewalk. When I lived in FL, we would
let the coconuts dry out before planting them. Should I do the same
thing with these miniature-sized palm tree seeds, or can I just plant
them now.
