Pinus virginiana (Virginia Pine, Jersey Pine, Spruce Pine, Scrub Pine)


Michael's Opinion

Pinus virginiana grows well in poor, dry soil and is often used for reforestation purposes. Once called a "forest weed" or "scrub pine", it is now frequently used as a Christmas tree. This fine textured tree grows extremely well in full sun and poor soils.

Description and Growing Information

General DescriptionPinus virginiana is a scrubby evergreen tree with yellow / green, flexible needles and long, horizontal branches and a relatively short trunk covered with orange-red bark.
ID CharacteristicYounger trees have orange-brown bark covered with thin scaly plates that turns orange-red and more rigid as the tree matures.
ShapeThe crown shape is round with irregular uniformity making it fairly sparse and unsightly.
LandscapeA relatively fast growth rate makes it very good for reforestation where clear cutting or fire has occurred.
PropagationBy seed: cold stratification is required as well as soaking for 24 hours and exposure to full sunlight before sowing. Seedlings need relatively dry soil; growth decreases without proper amounts of magnesium and potassium. Grafting is also possible but there tends to be only a 65% success rate with this method.
CultivationGrows best in clay, loam or sandy soils with a pH of 4.5 - 7.5. Suited to well drained soils and less tolerant of wet sites. It is very drought and salt tolerant and grows well in course to medium textured soils.
PestsNo serious pests or diseases of note.
Notable SpecimensThe Arnold Arboretum, Boston, Massachusetts, United States of America. Westonbirt, The National Arboretum, Tetbury, Gloucestershire, England.
HabitatGrows naturally in poor, dry soils at elevations of 15 - 760 m. Does not grow well in shallow, chalky soils with too much water. It can be found growing in abandoned farmlands and in places where forest fires have occurred.
Bark/Stem DescriptionYoung bark is smooth and reddish in colour that matures into shaggy, scaly textured, brown-orange bark that tends to be quite thick.
Flower/Leaf Bud DescriptionConical and acuminate with dark brown, resinous scales ranging from 0.8 - 1.3 cm in length.
Leaf DescriptionThere are two needles per fascicle in a dark grayish-green colour. They range from 4.1 - 7.1 cm in length and are rigid and often twisted.
Flower DescriptionMonoecious with male flowers yellow and cylindrical and female flowers yellow-red and curved.
Fruit DescriptionRange from 3.8 - 6.4 cm in length with conical to ovoid cones covered in brown-red scales.
Colour DescriptionFoliage stays green throughout the seasons. The fruit is brown and twigs have a reddish colour.
Texture DescriptionTends to be a finely textured tree in the early stages, becoming more rough and scaly as it matures.
