Jack Pine (Pinus banksiana)

Pine family, Pinaceae

Origin: eastern and central Canada, the north-eastern U.S.A. 

Habitat in the original area: sandy soils and rocky slopes

Habitus: A low tree or shrub 5–15 metres tall. The branches in the crown are sparsely and irregularly distributed. They are often twisted.

Leaf: The buds are shiny as they contain a large amount of resin. The light green needles, 2–4 centimetres long, grow in pairs in a bundle. They are twisted and slightly serrated on the edge. 

Bloom, fruit: Conical, twisted cones often grow in pairs on a twig, on which they sit firmly and from which they are difficult to separate. The cones have no spikes on the surface. They can last for several years closed. 

Interesting fact: It is not a very popular tree for planting due to its twisted appearance. Therefore, it can rarely be seen in parks. It is tolerant of drought and fires.
