UK Champion Quercus ×andegavensis

By Charles Snyers ... | May 17, 2014

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.
