The only oak species endemic to Africa is rare in cultivation. It shouldn't be.
Last Monday, I visited Roath Park in Cardiff, Wales with IOS member Tony Titchen and a small group of members of the International Dendrology Society (some of them also members of the IOS). The first sizable tree we came across was the UK champion Quercus ×andegavensis. Quercus ×andegavensis Hy is a hybrid between Q. pyrenaica and Q. robur (See our oaknames database). The tree was measured in 2004. It had a height of 24 meters and a diameter of 121 centimeters.
