Cultivars and their differences:

These plants are cultivars of a species that is native to the Chicago Region, according to Swink and Wilhelm’s Plants of the Chicago Region. Cultivars are plants produced in cultivation by selective breeding or via vegetative propagation from wild plants identified to have desirable traits.

Blue Shag Eastern white pine (Pinus strobus ‘Blue Shag’):

A dwarf variety growing only 2 to 3 feet high.

Dwarf Eastern white pine (Pinus strobus ‘Nana’ ): 

A compact or dwarf cultivar, 3 to 5 feet wide and tall.

Fastigiate Eastern white pine (Pinus strobus ‘Fastigiata’ ):

This narrow, upright cultivar grows 30 to 50 feet tall and 10 to 20 feet wide.

Weeping Eastern white pine (Pinus strobus ‘Pendula’ ):  

Typically 15 to 20 feet high and 12 to 15 feet wide. Blue-green needles cascade from twisting, weeping branches. This weeping form may require some training to produce a leader that will affect the ultimate height and spread of the plant.
