Holm oak, Holly oak. Usually a small or medium sized dense evergreen tree in Britain, originating from SW Europe but now naturalised along many parts of the coast of S.England. Grows about 7 m in 10 years. These seedlings are grown from seeds collected from local trees which bear sweet acorns with very little astringency. The seeds are edible after washing (raw or cooked) with a fine flavour. Roasted seeds can be used to make a coffee. Makes a good maritime hedging plant and the wood makes good fuel and charcoal. Tolerates quite deep shade; hardy to about -15°C.
