denser.


'Red Robin' appears to be a variety within P. fraseri, about half the
size of the usual 'Birmingham'. Since 'Birmingham' can grow 10-15 feet
high and equally wide, that would make 'Red Robin' 5-7 feet high and
again equally wide. Thus, I would not plant them closer than 3 feet
apart.

If spaced them very tightly - say one foot or less - what would happen?
The roots would interact in a way that might kill the plant?

Thanks for the other ideas on aligning adjacent rows. But I do wonder in
that case if you would end up starving one side of each row of sunlight.
