Taxon Description:
A small deciduous tree, sometimes shrubby, to about 10 m tall and usually found on sandy soils. The rigid shoots are densely covered in grey hairs when young and the bark soon cracks into small dark squares. Leaves elliptic to obovate to 10 cm long, narrowed to the base, untoothed, or occasionally with few shallow lobes and ending in a short point. They are blue-green to glossy green above and densely covered in white hairs beneath. Acorns ovoid to nearly rounded, about 1.5 cm long, ripening in the second year in a short-stalked or sessile cup. Although hardy, this species is rare in cultivation and slow-growing but has reached more than 4 m eight years after planting at the Hillier Gardens where it was first grown in the 1970s. It prefers a well drained soil in a warm, sunny site.We have two trees, one is doing well, the other is rather untidy and has been forced to grow upwards but is now also doing well at 5 m in a sheltered spot near the Tapir Orchard.
