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’re perennial in warm climates, but you’ll need to dig up the bulbs in the fall in zones 8 and colder to save for next year. They grow in sun or shade but need afternoon shade in hot climates.

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]
This member of family Pinaceae grows to the height of 20–30 m (66–98 ft) with a trunk diameter of 35–80 cm (14–31 in). The needles are in bundles of three to five, 5–10 cm (2–4 in) long, or rarely to 15 cm or 6 in, and are a bright glossy green to yellowish-green.
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).
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).
