Pinus canariensis aka Canary Pine

Pinus canariensis, also known as the Canary Island pine, is a large evergreen tree belonging to the conifer family Pinaceae. It is native and endemic to the outer Canary Islands in the Atlantic Ocean, including Gran Canaria, Tenerife, El Hierro, and La Palma. This subtropical pine species is highly adaptable to a wide range of rainfall regimes, from less than 300 mm to several thousands, but does not tolerate low temperatures or hard frost, surviving temperatures down to about −6 to −10 °C. It is one of the most drought-tolerant pines and can live with less than 200 mm of rainfall per year under warm conditions. The Canary Island pine is the tallest tree in the Canary Islands, with a height of 30–40 m and a trunk diameter of 100–120 cm, exceptionally up to 60 m tall and 265 cm in diameter. The green to yellow-green needle-like leaves are in bundles of three, 20–30 cm long, with finely toothed margins and often drooping. This pine is one of the most fire-resistant conifers in the world, as it can survive wildfires and regenerate from the glaucous epicormic shoots growing from the lower trunk. The cones are 10–18 cm long, 5 cm wide, glossy chestnut-brown in color, and frequently remaining closed for several years. The Canary Island pine is closely related to the Chir Pine from the Himalaya and the Mediterranean pines Pinus pinea, Pinus halepensis, Pinus pinaster, and Pinus brutia from the eastern Mediterranean. The native range of the Canary Island pine has been somewhat reduced due to over-cutting, and now only the islands of Tenerife, La Palma, and Gran Canaria still have large forests. It is the vegetable symbol of the island of La Palma. The Canary Island pine can also be grown as a rare houseplant that needs regular watering and long-lasting, direct light less than 1 foot from a window. It prefers well-draining soil and does not require added fertilizers if repotted each time it doubles in size.
