The acorn is the nut of the oaks and their close relatives (genera Quercus, Notholithocarpus and Lithocarpus, in the family Fagaceae). It usually contains a seedling surrounded by two cotyledons (seedling leaves), enclosed in a tough shell known as the pericarp, and borne in a cup-shaped cupule.
The leaves are a distinct deep purple-crimson on new growth, soon turning glossy green above, glaucous blue-green below, 60–13 mm long and 20–50 mm broad, with a serrated margin. The flowers are catkins , and the fruit are acorns 1–1.6 cm long, with series of concentric rings on the outside of the acorn cup (it is in the " ring-cupped oak ...
This tree has a coarse texture and leaves that are dark that attract attention as a specimen plant. [25] This tree is not a good fit for small areas and needs to be put in a large open area in order to form due to its size. Aesculus flava tends to produce large amounts of leaf and flower litter in the summer and fall. The fruit makes good food ...
Acorns were actually farmed very early in human history, but to make them edible you have to soak them and treat them. Sure, you see animals eat them all the time, but animals also eat tree bark ...
The fruit is an acorn, maturing about 18 months after pollination, 2–3 cm (3 ⁄ 4 – 1 + 1 ⁄ 4 in) long and 2 cm broad, bi-coloured with an orange basal half grading to a green-brown tip; the acorn cap is 1.5–2 cm (5 ⁄ 8 – 3 ⁄ 4 in) deep, densely covered in soft 4–8 millimetres (3 ⁄ 16 – 5 ⁄ 16 in) long 'mossy' bristles.
The leaves turn red in autumn. The fruit is an acorn2.5–3.5 cm (1– 1 + 1 ⁄ 2 in) long and 2–2.5 cm (3 ⁄ 4 –1 in) broad, borne on a 2–3 cm peduncle, maturing in the fall, about 6 months after pollination. [4] The tree only bears heavy acorn crops at intervals of several years. [5]
The acorns and leaves contain tannic acid, [5] which helps to guard against fungi and insects. [6] There are some 500 extant species of oaks. [7] Trees in the genus are often large and slow-growing; Q. alba can reach an age of 600 years, a diameter of 13 feet (4.0 m) and a height of 145 feet (44 m). [8]
Acorns, pine cones, etc.: Those things that mature fairly dry can be hung just as they are, strung, glued, or otherwise attached to just about anything that can’t outrun you and a glue gun.
