Nordman Fir (Non Drop)
 
This non-drop variety has larger and bushier needles than the Norway spruce, a beautiful tree and a popular choice. The needles are dark green and soft to touch. Any cut tree will need watering regularly to keep it at its best, but these trees are known for retaining their needles well. 

Norway Spruce (traditional)
 
The Norway Spruce is the original  variety and is the tree that smells most like Christmas! 
As with the Nordman Fir, it will require regular watering to keep it looking fresh and at its best once cut.
