Canaan Fir Christmas trees
Balsam's scent on sturdier branches.
Canaan is botanically a variety of balsam, and it behaves like balsam that has been to the gym. The same strong fragrance, sturdier branches, and needle retention that sits closer to Fraser than to its parent.
It tends to fill out more than a balsam, so if you have a corner to fill rather than a narrow space to slot into, it does the job without looking heavy.
People who cannot decide between Fraser and Balsam usually end up happy with this one, which is exactly what it is for.
