About
Quercus dentata, the Daimyo oak, is a medium-sized, deciduous tree to around 15 m producing very large leaves around 30 cm long that emerge in spring, mature to dark green and turn orange before hanging brown on the tree all winter. The acorns have cups with long, curved, bushy scales. A bold and architectural oak for a large, sunny garden.
