Sequoiadendron giganteum), the oldest (non-clonal) organism ( i.e. The most famous of these are the larches (genus Larix), however, there are others such as baldcypress (genus Taxodium) and the dawn redwoods (genus Metasequoia). Sequoia sempervirens), the heaviest (non-clonal) organisms ( i.e. The conifers include some of the most extreme organism on Earth: the tallest organisms (i.e. Available: Biodiversity Heritage Library, accessed 2021.12.19. ![]() Journal of the Arnold Arboretum 64:475-481. It is usually light in color and cheaper, therefore used for building inexpensive furniture or used for paper pulp. Reminiscences of collecting the type specimens of Metasequoia glyptostroboides. Conifer evergreens are sometimes referred to as "softwoods" because they have wood that is light-weight, weak in shear (along the grains), but strong in tension. In addition, conifers have many adaptations to survive in cold, dry conditions: needle-like leaves, hypodermis in leaves, sunken stomata, narrow xylem cells, and resin canals to name some. Most polar, and many temperate, conifers have a pyramid shape with weak branches: an adaptation to shed snow. Give trees good soil, additives, and water. Taxus (yew), Pinus (pine), Picea (spruce), and Abies (fir) cannot survive on waterlogged soil. One of the most versatile conifers is Taxodium distichum, which can grow in water or on rocks. ![]() This is a tree of very cold climates, growing to the tree line across North America. Choose Larix, Taxodium, Metasequoia, or Thuja (arborvitae). Conifers dominate in taiga biomes, as well as temperate areas with poor soils. Larix laricina, commonly called tamarack, eastern larch, American larch or hackmatack, is a deciduous conifer whose green needles turn a showy yellow in fall before falling to the ground as winter approaches. The conifers are cone-bearing gymnosperms that are most frequently evergreen trees, but some are deciduous ( e.g. ![]()
