Tammy, the
seed will be on the
flat side of those "flaps" that weezie mentioned. (Actually, they're not flat, but are just a bit curved in, like a spoon.) You'll be able to spot the
seed right off, cuz they
look like seeds & they have a woody-looking "wing" when you first pull them out of the cone.
It takes a long time to get a
pine tree seed started, & they ALWAYS have to go through a winter
(or be stratified in the refrigerator) in order to germinate.
Personally, I think it'd be much quicker to dig up a first year
seedling for your friend, if she wants to grow a
tree in her yard.
