Daimyo oak is a large deciduous tree from East Asia with very big leaves, usually grown as a small, irregular tree or shrub in cultivation. It is a hardy, sun-loving oak that does best in a deep, moist but well-drained soil.

About
Quercus dentata, also called Japanese emperor oak, daimyo oak, or Korean oak (Japanese: 柏, kashiwa; traditional Chinese: 柞櫟; simplified Chinese: 柞栎; pinyin: zuòlì; Korean: 떡갈나무, tteokgalnamu), is a species of oak native to East Asia, including north-central and southern China, Japan, Korea, the Russian Far East (Khabarovsk and Primorsky krais and the Kuril Islands), Manchuria, Mongolia, and Taiwan. The name of the tree is often translated as "sweet oak" in English to distinguish it from Western varieties. It is placed in section Quercus.
How to grow it
Quercus dentata was introduced to the British Isles in 1830, where it is occasionally grown in botanical gardens. It is usually smaller in cultivation than in the wild, growing to a small angular tree or large irregular shrub. Notable specimens include one at Osterley Park, 14 m (46 ft) tall and 1.5 m girth, and the largest, 18 m (59 ft) tall, at Avondale Forest Park, County Wicklow, Ireland.
Where it grows
Quercus dentata (Qd) cannot tolerate the extreme cold of northern Hokkaido, but Quercus crispula (Qc) can. In more southerly parts of Hokkaido, Q. dentata lives in coastal areas while Q. crispula tends to live more inland. In the more northern parts of the island, these two species have experienced introgression and they are interfertile, producing shoots that grow and can reproduce; resulting in a coastal Qc ecotype with Qd-like traits. The coastal Qc are intermediary between the two parent species in genotypes and phenotypes.
Uses
In Korean cuisine, its acorns (in Hangul: 도토리, dotori) have been used since the Three Kingdoms. A notable food is dotorimuk.
