In the fields of horticulture and botany, the term deciduous (/ d ɪ ˈ s ɪ dʒ u. ə s /) [1] [2] means "falling off at maturity" [3] and "tending to fall off", [4] in reference to trees and shrubs that seasonally shed leaves, usually in the autumn; to the shedding of petals, after flowering; and to the shedding of ripe fruit.
In Japan, iromomiji is used as an accent tree in Japanese gardens, providing gentle shade next to the house in the summer and beautiful colors in autumn. Many cultivars have characteristics that come into prominence during different seasons, including the color of new or mature leaves, extraordinary autumn color, color and shape of samaras, or ...
Autumn leaf color is a phenomenon that affects the normally green leaves of many deciduous trees and shrubs by which they take on, during a few weeks in the autumn season, various shades of yellow, orange, red, purple, and brown. [1]
A 10-year-old tree is typically about 5 m (20 ft) tall. As with most trees, forest-grown sugar maples form a much taller trunk and narrower canopy than open-growth ones. [citation needed] The leaves are deciduous, up to 20 cm (7.9 in) long and wide, [8] palmate, with five lobes and borne in opposite pairs. The basal lobes are relatively small ...
Elaeagnus umbellata grows as a deciduous shrub or small tree, typically up to 3.5 metres (11 ft) tall, with a dense crown. [5] [6] It commonly bears sharp thorns in the form of spur branches. [6] Flowers are fragrant, occur in clusters of white to yellow, are 8–9 mm in length and 7 mm in diameter, and have four lobes. [5] [6]
The leaves appear relatively late in spring, and turn a clear pale yellow in autumn. The leaflets fold together in wet weather and at night , as some change of position at night is a habit of the entire leguminous family. Young trees are often spiny, especially on root suckers and branches near the ground; mature trees often lack spines.
When autumn arrives and leaves start to fall on lawns and walkways, the traditional method of raking can seem daunting. Thankfully, there are alternative techniques that not only simplify leaf ...
Marcescence is most obvious in deciduous trees that retain leaves through the winter. Several trees normally have marcescent leaves such as oak (Quercus), [5] beech (Fagus) and hornbeam (Carpinus), or marcescent stipules as in some but not all species of willows . [6] All oak trees may display foliage marcescence, even species that are known to ...
