    Paulownia tomentosa. Paulownia is a genus of angiosperm trees, and one of the fastest-growing trees in the world. [12] Paulownia tomentosa can grow over 30 metres (98 ft) tall and has large heart shaped leaves ranging from 10–20 centimetres (4–8 in) wide and 15–30 centimetres (6–12 in) long with a 10–20 centimetres (4–8 in)-long petiole.

    [3] [4] It is an extremely fast-growing tree with seeds that disperse readily [5] and is considered an invasive exotic species in North America [6] that has undergone naturalisation in large areas of the Eastern US, [7] even though it might be able to successfully get established through seeds only under ideal conditions. [8]

    en.wikipedia.org/wiki/Paulownia_elongata

    Paulownia elongata is a species of tree in the family Paulowniaceae, native to Asia. The plant's leaves are very large and pubescent ('fuzzy—hairy'). This species can withstand a very wide range of environmental conditions. It does not grow at higher altitudes however.

  5. List of tallest trees - Wikipedia

    en.wikipedia.org/wiki/List_of_tallest_trees

    Two main opposing forces affect a tree's height; one pushes it upward while the other holds it down. By analyzing the interplay between these forces in coast redwoods (Sequoia sempervirens), a team of biologists led by George Koch of Northern Arizona University calculated the theoretical maximum tree height or the point at which opposing forces balance out and a tree stops growing.

  6. Ochroma - Wikipedia

    en.wikipedia.org/wiki/Ochroma

    A deciduous angiosperm, Ochroma pyramidale can grow up to 30 m tall, and is classified as a hardwood despite the wood itself being very soft; it is the softest commercial hardwood and is widely used because of its light weight. Balsa trees grow extremely fast, often up to 27 metres in 10–15 years, and do not usually live beyond 30 to 40 years.

    Native ash species, including white ash (pictured), have been declining rapidly this century due to predation by the emerald ash borer. [1] Silvics of North America (1991), [2] [3] a forest inventory compiled and published by the United States Forest Service, includes many hardwood trees.

  8. Platanus occidentalis - Wikipedia

    en.wikipedia.org/wiki/Platanus_occidentalis

    It is a fast-growing, early-mid successional hardwood tree species. [17] Its life cycle follows the pattern of a "weedy" species: it grows mature enough to reproduce rather young and produces large numbers of wind-distributed seeds. [18]

  9. Khaya senegalensis - Wikipedia

    Mature tree next to Fanling Station. African mahogany is a fast-growing medium-sized tree which can obtain a height of up to 15–30 m (49–98 ft) in height and 1 m (3 ft 3 in) in diameter. The bark is dark grey to grey-brown while the heartwood is brown with a pink-red pigment made up of coarse interlocking grains.
