Pinus canariensis is a large evergreen tree, growing to 30–40 metres (98–131 feet) tall and 100–120 centimetres (39–47 inches) diameter at breast height, [3] exceptionally up to 56 m (184 ft) tall and 988 cm (389 in) girth (314 cm (124 in) diameter). [4]
The mean annual increment (MAI) or mean annual growth refers to the average growth per year a tree or stand of trees has exhibited/experienced up to a specified age. For example, a 20-year-old tree that has a stem volume of 0.2 m 3 has an MAI of 0.01 m 3 /year.
They provide food for pollinators early in the growing season. Some varieties are short-lived but self-sow, with new plants popping up in subsequent years. Hummingbirds love them!

Pinus, the pines, is a genus of approximately 111 extant tree and shrub species. The genus is currently split into two subgenera: subgenus Pinus (hard pines), and subgenus Strobus (soft pines). Each of the subgenera have been further divided into sections based on chloroplast DNA sequencing [1] and whole plastid genomic analysis. [2]
Members of the family Pinaceae are trees (rarely shrubs) growing from 2 to 100 metres (7 to 300 feet) tall, mostly evergreen (except the deciduous Larix and Pseudolarix), resinous, monoecious, with subopposite or whorled branches, and spirally arranged, linear (needle-like) leaves. [3] The embryos of Pinaceae have three to 24 cotyledons.
At altitude, in the cool relatively wet climate, forests of the endemic pine Pinus canariensis thrive. Many of the plant species in the Canary Islands, like the Canary Island pine and the dragon tree , Dracaena draco are endemic, as noted by Sabin Berthelot and Philip Barker Webb in their work, L'Histoire Naturelle des Îles Canaries (1835–50).
They grow on well-drained, usually sandy soil, characteristically in pure stands. [9] Longleaf pine also is known as being one of several species grouped as a southern yellow pine [10] or longleaf yellow pine, and in the past as pitch pine (a name dropped as it caused confusion with pitch pine, Pinus rigida).
