Dark green to greenish blue, stiff and less than an inch long. White spruce has a good natural shape. Needles have an unpleasant odor when crushed. Good, but keep indoors for no more than a few days. Choose a location that will be cool and mist regularly or run a humidifier nearby.
Living trees are a permanent memento of the holiday season, but they're a challenge.
If kept too long inside a heated room, the tree will break dormancy. Then new growth will be damaged when the tree is moved back outside after the holidays. If using a living tree, dig the planting hole in advance. Reserve the removed soil in the garage or somewhere it won't freeze. Some trees will not survive.
