Plants, People, Planet. 1 (4): 323–335. doi: 10.1002/ppp3.39.Trees create a visual impact in the same way as do other landscape features and give a sense of maturity and permanence to park and garden. They are grown for the beauty of their forms, their foliage, flowers, fruit and bark and their siting is of major importance in creating a landscape. They can be grouped informally, often surrounded by plantings of bulbs, laid out in stately avenues or used as specimen trees. As living things, their appearance changes with the season and from year to year. [148] Loha-unchit, Kasma. "Kaffir Lime: Magrood". Thai Food and Travel. Archived from the original on 9 May 2019 .

The tree is not an immutable biological category but rather a human concept based on visual criteria. Perhaps a general definition would describe a tree as a perennial woody plant that develops along a single main trunk to a height of at least 4.5 metres (15 feet) at maturity. This may be contrasted with a shrub, which might be loosely defined as a woody plant with multiple stems that is, in most cases, less than 3 metres (about 10 feet) tall. However, a species fitting the description of either in one area of the world might not necessarily do so in other regions, since a variety of stresses shape the habit of the mature plant. Thus, a given woody species may be a tree in one set of habitats within its range and a shrub elsewhere. For example, the spruce and fir may thrive in the tree form at the base of a mountain but assume a shrub form near the mountaintop, the variation due principally to stresses exerted by such environmental conditions as altitude, temperature, and oxygen tension.

Wood is pulped for paper and used in the manufacture of cardboard and made into engineered wood products for use in construction such as fibreboard, hardboard, chipboard and plywood. [127] The wood of conifers is known as softwood while that of broad-leaved trees is hardwood. [128] Art At least 120 drugs come from plant sources, many of them from the bark of trees. [142] Quinine originates from the cinchona tree ( Cinchona) and was for a long time the remedy of choice for the treatment of malaria. [143] Aspirin was synthesised to replace the sodium salicylate derived from the bark of willow trees ( Salix) which had unpleasant side effects. [144] The anti-cancer drug Paclitaxel is derived from taxol, a substance found in the bark of the Pacific yew ( Taxus brevifolia). [145] Other tree based drugs come from the paw-paw ( Carica papaya), the cassia ( Cassia spp.), the cocoa tree ( Theobroma cacao), the tree of life ( Camptotheca acuminata) and the downy birch ( Betula pubescens).

A small group of trees growing together is called a grove or copse, and a landscape covered by a dense growth of trees is called a forest. Several biotopes are defined largely by the trees that inhabit them; examples are rainforest and taiga (see ecozones). A landscape of trees scattered or spaced across grassland (usually grazed or burned over periodically) is called a savanna. A forest of great age is called old growth forest or ancient woodland (in the UK). A very young tree is called a sapling. Coder, Kim D. (August 1999). "Secondary Growth Anatomy and Tree Rings".

Retrieved 23 September 2014.Some trees such as Alder ( Alnus species) have a symbiotic relationship with Frankia species, a filamentous bacterium that can fix nitrogen from the air, converting it into ammonia. They have actinorhizal root nodules on their roots in which the bacteria live. This process enables the tree to live in low nitrogen habitats where they would otherwise be unable to thrive. [55] The plant hormones called cytokinins initiate root nodule formation, in a process closely related to mycorrhizal association. [56] Many trees have flowers rich in nectar which are attractive to bees. The production of forest honey is an important industry in rural areas of the developing world where it is undertaken by small-scale beekeepers using traditional methods. [117] The flowers of the elder ( Sambucus) are used to make elderflower cordial and petals of the plum ( Prunus spp.) can be candied.
