Some of the needled evergreen choices to use from your landscape might include the following. Arborvitae, cedar or chamaecyparis all have somewhat thick, flat needled evergreen fans. They are good for textural accents. Balsam fir, Douglas fir and Fraser fir are popular, soft needled and nice to work with. They hold their needles relatively well and are good to bring indoors.
Junipers are very prickly, but they have very attractive blue berries.
The berries often have a dusty cast. Juniper looks great in pewter containers. Scotch pine makes a prickly, stiff, good space filler in an arrangement. Blue Spruce and spruce are also prickly, stiff and good space fillers. The tips have good color, but dry out quickly.
