Regions / Wyoming
Selecting plants suited to the climate of Wyoming is a key step to success.
A plant's performance is governed by many climate-related factors, including the length of the growing season, the amount of rainfall, winter lows, summer highs, wind, or humidity. Various initiatives have taken place to determine how well plants would withstand the cold winter temperatures (Plant Hardiness Zones) or when plants would start suffering from the heat (Plant Heat Zones). A more sophisticated approach has been followed by Sunset, which defines Climate Zone Maps based not only on hardiness or heat tolerance but also on precipitations, wind, humidity, and various other climate-related factors.
Highly popular, Abies balsamea ‘Nana’ is a dwarf, aromatic, evergreen conifer of globose habit, forming a broad mound with numerous short branches, adorned with a lush foliage of dark green needles radially arranged around the stems. Slow-growing, 2-3 in. per year (5-7 cm), this Balsam Fir is a great choice for small gardens or rockeries. Perfect for adding year-round color to the garden.
One of the tallest firs in the world, Abies grandis (Grand Fir) is a large evergreen conifer of narrow, conical habit becoming round-topped or straggly with age.

They exude an orange aroma when crushed.
Abies lasiocarpa ‘Green Globe’ is a semi-dwarf, evergreen conifer of globose habit when young, becoming conical over time, and clothed in a lush foliage of short, soft, green needles. Slow-growing, 3-6 in. per year (7-15 cm), this Alpine Fir is a great choice for foundation plantings or rockeries.
Stately and elegant, Abies nordmaniana 'Golden Spreader' is a slow-growing evergreen conifer of great beauty, particularly in the winter garden. While this dwarf Nordman fir sports a soft green color in summer and fall, its needles turn bright golden-yellow in winter.

Majestic, award-winner Acer platanoides 'Crimson King' (Norway Maple) is a vigorous medium-sized deciduous tree prized for its large, rich purplish-crimson leaves that last throughout the summer and its purple fruits.
