Quercus ×kewensis – Fagaceae

Посмотреть цены и наличие
Medium-size to large tree with a broad oval, eventually round crown. The young twigs are light brown covered with short stellate hairs. The older bark is first grey and smooth but later almost black and grooved. The semi-evergreen leaves are oval to oval-elongated, 5 to 8 cm long. The margin is shallow-lobed with 5 - 6 rounded triangular lobes. The leaf is matt dark green on top and glossy, lighter green on the underside. The tree produces about 2.5 cm large acorns which ripen in two years. However the acorns usually fall from the tree before they are ripe. This species hybrid between Q. wizlizenii and Q. cerris was found in the Royal Botanic Garden Kew by coincidence in 1914. The hybrid species name kewensis refers to this. This park tree requires a sheltered site and cannot tolerate cold, drying wind.
