Genus name is the latin name for a kind of oak bearing edible acorns but applied by Linnaeus to this genus. [8] Aesculus was the Latin name that is given to an oak or any tree that has seeds that are eaten by livestock, while flava (or flavum) is the Latin word for yellow, referring to the buckeye's yellow flowers.

In Korea, an edible jelly named dotorimuk is made from acorns, and dotori guksu are Korean noodles made from acorn flour or starch. In the 17th century, a juice extracted from acorns was administered to habitual drunkards to cure them of their condition or else to give them the strength to resist another bout of drinking.
The acorns ripen in autumn, about six months after pollination. [9] It is a resilient tree that can survive temperatures below −20 °C (−4 °F), and that on occasion reach 47 °C (117 °F). [5] As opposed to Quercus ilex, its acorns have a very low level of bitterness tannins and so are generally sweet and a good energy source for livestock ...
Image credits: prolixia #13. One of the first staple foods is kinda weird: Acorns. Acorns were actually farmed very early in human history, but to make them edible you have to soak them and treat ...
The mildly sweet (but perhaps unpalatable) acorns are edible, ideally after leaching. [6] [29] The bitterness of the toxic tannic acid would likely prevent anyone from eating enough to become ill. [29] Native Americans ate the acorns raw and roasted, also using them to make a kind of flour. [5] The hardwood is hard and heavily ring-porous.
Acorns mature in one year for annual trees and two years for biannual trees. Acorn is encapsulated by a spiny cupule as characterized by the family Fagaceae. Flowers in the Quercus genera produce one flower per node, with three or six styles, as well as three or six ovaries, respectively. The leaves mostly lack a bristle on their lobe tips ...
The flowers are greenish-yellow catkins, produced in the spring. The acorns are very large, 2.5–5 cm (1–2 in) long and 2–4 cm (3 ⁄ 4 – 1 + 1 ⁄ 2 in) broad, having a large cup that wraps much of the way around the nut, with large overlapping scales and often a fringe at the edge of the cup. [3]
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.
