Abies fargesii (Farge's Fir)


Michael's Opinion

A evergreen tree native to China and may be considered an invasive species since it dominates nearly 50% of some forests. It is similar to most other trees in its genus but this particular species has especially interesting cones that are dark purple. It thrives in rich, well-drained soils and full sun exposure.

Description and Growing Information

General DescriptionA large, evergreen tree with thin, flat needle-like foliage, dark green on top, with a bluish-white pigment on the underside. Branches come out from the trees at a 90° angle, the bark is rigid and scaly in mature specimens and the female cones are a deep purple colour.
ID CharacteristicFemale cones are deep purple to almost navy blue colour.
ShapeVery tall, columnar to fastigiate in form.
LandscapeWith its columnar form, it may be considered ideal for placement along buildings.
PropagationPropagate from seed which should be sown in the late stages of spring. Soak the seeds in water for 24 hours, followed by a cold stratification period of least 30 days. At 5°C sow the seeds thinly and plant .5 cm deep in the soil. Young Abies are especially sensitive to light, so proper shade is absolutely necessary for the first 3-5 years.
CultivationRequires full sun and thrives in moist, alkaline, rich, well-drained soils.
PestsNo significant pests or diseases.
Notable SpecimensUniversity of British Columbia Botanical Garden, Victoria, British Columbia, Canada.
HabitatMountainsides, native to China.
Bark/Stem DescriptionBark is light grey in colour, fine and flakey when young becoming brown, course and rigid as it matures.
Flower/Leaf Bud DescriptionBuds are broad, oval-shaped and can be quite rigid. Purplish-red in colour and are quite resinous, 6-8 mm long and 4-5 mm wide. The bud scales are triangular, yellow to almost brown in colour and often persist for several years.
Leaf DescriptionLeaves are opposite in arrangement, very flat, thin and relatively soft to touch. They are 2-2.5 mm wide and can vary dramatically in length usually between 10-35 mm long. A deep green colour on top and a blue on the underside.
Flower DescriptionFlowers are small and insignificant.
Fruit DescriptionMale cones are tubular, 13 mm long and roughly 5 mm wide. The more recognizable and dominate cones are female. The female cones are about 50 mm long and 30-40 mm wide, very broad and obtuse in shape. When young they are a very deep shade of purple with hues of blue, and mature to a more purple-red tone. The black coloured seeds are elongated, 3-3.5 mm wide and up to 15 mm long.
Colour DescriptionFoliage is a very dark shade of green, female cones are an eye-catching shade of deep purple.
Texture DescriptionMedium.
