[1] [2] The underlying physiological mechanism is that trees transfer water and sap from the roots to the leaves through their vascular cells, but in some trees as autumn begins, the veins carrying the sap slowly close until a layer of cells called the abscission layer completely closes off the vein allowing the tree to rid itself of the leaf.

They typically measure 5–10 centimetres (2.0–3.9 in) in length. Flowers appear in the spring and are inconspicuous. [4] The beechnuts sit in a thin spiny husk and are less than 5 cm in diameter. [5] The triangular beech nuts are popular in autumn with birds, mice and squirrels. [citation needed] The green leaves become copper-toned in the fall.
The fruit is a triangle-shaped shell containing 2–3 nuts inside, but many of them do not fill in, especially on solitary trees. Beech nuts are sweet and nutritious, [7] can be eaten raw by wildlife and humans, [26] or can be cooked. [27] They can also be roasted and ground into a coffee substitute. [7] The leaves are edible when cooked. [7]
Both bear showy flowers in spring, which are followed by prickly or spiny capsules that split open in fall to release 1 or 2 nuts inside. Unlike actual chestnuts, the nuts of Aesculus species are ...
The crown is rounded and the bark is smooth and grey. The simple leaves are arranged alternately along the branch. They are broadest towards the base and have 7 to 11 pairs of veins. The nut has a short thick stalk, 15 millimetres (0.6 in) long. There are flattened green whiskers at the base of the husk of the nut. The flowers are wind ...
The bud of a Regent vine located between the stem and petiole.. The grape starts its annual growth cycle in the spring with bud break. In the Northern Hemisphere, this stage begins around March while in the Southern Hemisphere it begins around September when daily temperatures begin to surpass 10 °C (50 °F).
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.
People often use the simple mnemonic spring forward, fall back to remember to set clocks forward one hour (e.g., from 2 a.m. to 3 a.m.) in the spring and backward one hour (e.g., from 2 a.m. to 1 ...
