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]
Isoplexis is a section of four species of flowering plants within the genus Digitalis in the plantain family Plantaginaceae.The species of section Isoplexis differ from other plants in the genus Digitalis in that their monosymmetric (sometimes called zygomorphic) flowers have a distinctive large upper lip rather than large lower lip and the species are endemic to the Canary Islands (the ...
The blooms last many weeks, well into late spring to early summer. Bonus: Bunnies and deer tend to leave them alone. Fast Facts. USDA Hardiness Zone: 3 to 9. How Much Sun It Needs: Part sun to ...
The other two species, Pinus balfouriana and Pinus aristata, are also long-lived, though not to the extreme extent of P. longaeva; specimens of both have been measured or estimated to be up to 3,000 years old. [16] The longevity of the trees is believed to be related to the proportion of dead wood to live wood.
The pinyon jay (Gymnorhinus cyanocephalus) takes its name from the tree, and pinyon nuts form an important part of its diet. It is very important for regeneration of pinyon woods, as it stores large numbers of the seeds in the ground for later use, and excess seeds not used are in an ideal position to grow into new trees.
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 ).
Younger specimens, without a sizeable trunk, are more prone to freezing. It is a slow-growing tree, increasing in height by up to 60 cm per year, [8] and is propagated exclusively by seed. Mature P. canariensis are often used in ornamental landscaping and can be fairly readily collected and transplanted to a new planting location.
P. radiata is a versatile, fast-growing, medium-density softwood, suitable for a wide range of uses and valued for rapid growth, as well as desirable lumber and pulp qualities. [5] [6] Its silviculture reflects a century of research, observation and practice. [5] It is often considered a model for growers of other plantation species. [5]
