They offer a wide variety in foliage color, texture, and size for any decorating need. White Pine is a traditional green with a soft, graceful, bluish-green appearance. Another popular commercial choice is the fragrant, forest-green Princess Pine. Better choices for a lacy foliage are the true cedars. This can be prevented by spraying the cones with lacquer or acrylic before arranging.
Firs are the short-needled greens.
Douglas Fir is the traditional commercial green, with needles spiralling around the stem. Noble Fir has a greater needle density in a rich blue-green color and very good tolerance of hot, dry indoor conditions. Silver Fir is another commercial green that features rich-green needles with silver undersides. White Fir has medium-green needles that lie flat along the stem. Canadian Hemlock is popular as another short-needled green, having needles that lie flat along the stem.
