Fir(Abies) is a genus of conifers with over 50 species. Easy to grow and frost-resistant fir trees thrive in cooler climates and moist soils. The variety of species and varieties makes these evergreen trees very popular.Dwarf and miniature fir varietieslook great in small gardens, rockeries, and even in pots. We presentfir species and varietiesrecommended for gardens.

Common fir (Abies alba), also called white fir, is an evergreen coniferous tree with a conical or columnar crown, growing up to 20-50 m in height. It is long-lived and can live up to 400 years. The needles, 1.5 to 3.0 cm long, are blunt tipped, green on the upper side and silvery with two white stripes on the underside. Fir blooms in spring. The cylindrical, erect, green cones turn brown as they mature.
Silver fir grows well in shady and humid places.It does not tolerate drought and environmental pollution. The soil for fir should be moist and fresh with a slightly acidic reaction. Silver fir is quite sensitive to low temperatures (it belongs to the plant frost resistance zone 5B) and in regions with harsher winters, young trees may freeze.

The most common varieties of fir in gardens arecommonwith limited growth strength:
Silver fir 'Brinar'- is a frost-resistant variety reaching 2-3 m in height. It has a nice, dark green conical crown. It looks good on flower beds, in rock and heather gardens.
Silver fir 'Compacta'- has a compact, conical crown and grows up to 2-4 m in height. It grows well in the shade, but needs a lot of sun to form a nice crown. It works best in regions with milder and humid climates.
Silver fir 'Franta'- this is a miniature variety that is only 0.5 m high after 10 years. It branches heavily, creating a compact, dense crown. Young, light green shoots contrast nicely with the dark green of older needles. The variety grows well both in the shade and in the sun and is fully frost-resistant.
Silver fir 'Ibergeregg'- is a dwarf variety growing up to 1.5 m in height, with an irregular, wide habit. Ruffled needles and small size make it look great in rocky and heather gardens.
Silver fir 'Pendula'- it is not tall, grows up to 2 m and stands out due to its picturesque habit. The columnar shape blends beautifully with the hanging side shoots.
Silver fir 'Pyramidalis'- this is a slow growing variety with a narrow columnar habit. After many years, it can reach a height of 10 m. It is sensitive to frost, dry winds and water shortages.
Caucasian fir (Abies nordmanniana) occurs naturally in northwestern Turkey and in the mountains of the Caucasus. It grows quite quickly, growing up to 10 m in height in our climate. It is characterized by a shaped crown, initially pyramidal, conical with age. The horizontally arranged branches extend all the way to the ground. Long, dark green needles on the underside have two white stripes.

Caucasian fir, like other species of fir , prefers fresh and moist soils and positions sheltered from the wind. It grows best in the vicinity of water reservoirs, requires high air humidity. It is not fully frost resistant - frost resistance zone 6B. It does not tolerate polluted air. In Poland, it is one of the most popular conifers grown in gardens and as Christmas trees.
Caucasian fir varieties recommended for gardens :
Caucasian Fir 'Aurea'- a slow growing variety with a conical shape, growing up to 7-8 m in height. A characteristic feature is the golden yellow color of young needles, which darkens with time. The variety requires a sunny position and fertile, fairly moist soil.
Caucasian Fir 'Barabits Compact'- has a spherical shape and grows up to 0.5 m in height after 10 years. Young growths have an intense light green color. It retains its compact habit and attractive appearance only in sunny places.Sensitive to frost (frost resistance zone 6B).
Caucasian Fir 'Golden Spreader'- is a dwarf variety reaching 1 m in height after 10 years. It is characterized by a compact crown with a characteristic depression at the top. Shiny golden needles, the underside is almost white. Plant hardiness zone 7A.
Caucasian fir 'Munsterland- is a variety with a wide habit, reaching up to 0.5 m in height. Does not produce a conductor, the crown folds to a dense green carpet.
Caucasian fir 'Pendula'- grows up to 4-5 m in height, and its side shoots hang down along the trunk. It looks great as a solitaire. Quite sensitive to frost, classified in the frost resistance zone 7A.
Caucasian Fir 'Robusta'- is a fast-growing variety growing up to 10 m high and 1 m wide. The slender, irregular crown looks like it is covered with snow. This is due to thick, stiff needles, twisted with the white underside to the top.
Mountain Fir(Abies lasiocarpa) occurs naturally in the mountainous regions of North America. It reaches 20 m in height and its long needles have an interesting gray or blue shade of green. Mountain fir gives birth to cones only when it exceeds the age of 50. It grows well in sunny or slightly shaded places, in a fertile and moist soil. It is a species that is almost completely frost-resistant (hardiness zones 4-5), but in our conditions, spring frosts can damage young shoots.

Mountain fir 'Green Globe'- is a dwarf variety growing up to 1.5 times in height, with a spherical shape. The blue-green needles are long and cover the shoots densely. It grows best in permeable and slightly moist soils and in a place slightly sheltered from the sun.
Californian fir (Abies concolor), also called single-colored fir, occurs in its natural state mainly in mountainous regions of North America. It is a large tree with a conical, regular crown. Old specimens tend to lose the lowest branches. This species is popular for its long, soft, blue-green, pale needles that smell beautiful.
Californian fir is easy to grow , it tolerates periodic droughts, polluted air and frosts (plant hardiness zone 4). Moist, fertile, permeable soils with a reaction close to neutral and sunny positions are the key to success in the cultivation of this species of fir. In such conditions, the tree has a beautiful habit and color, and does not lose its lowest branches.
