We presently grow 18 species from seed in our greenhouse and are going to try a few more in future years. The seed all comes from highly reputable sources. The different species of seedlings we grow are listed just below.
Balsam fir, Fraser fir, Canaan fir, Nordmann fir and Concolor ( or white) fir.
Douglas fir (not a true fir like the ones above).
Blue spruce, Norway spruce, White spruce, Meyer spruce and Black Hills spruce.
White pine, Ponderosa pine, Austrian pine, Southwestern white pine and Red pine
White cedar (also known as arborvitae) and red cedar.
Within a couple years we hope to have Grand fir and Arizona Cypress available.
