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] Battey, N. H. (August 2003). "August-learning about summer". Journal of Experimental Botany. 54 (389): 1797–1799. doi: 10.1093/jxb/erg225. PMID 12869517.

To the ancient Celts, certain trees, especially the oak, ash and thorn, held special significance [158] as providing fuel, building materials, ornamental objects and weaponry. Other cultures have similarly revered trees, often linking the lives and fortunes of individuals to them or using them as oracles. In Greek mythology, dryads were believed to be shy nymphs who inhabited trees. a b Taylor, Leslie (13 October 2000). "Plant Based Drugs and Medicines". The Healing Power of Rainforest Herbs.

Retrieved 18 December 2021.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] Earle, Christopher J., ed. (2017). "Sequoia sempervirens".

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. Loha-unchit, Kasma. "Kaffir Lime: Magrood". Thai Food and Travel.

In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees.
