Yew species grow slowly and are long-lived. In the Yew Collection at The Morton Arboretum, look for the many cultivars of Japanese yew (Taxus cuspidata). Notable specimens in this collection are several mature, upright forms of Anglo-Japanese yew (Taxus x media). These include Pilaris Anglo-Japanese yew (Taxus x media 'Pilaris'), Sentinel Anglo-Japanese yew (Taxus x media 'Sentinalis'), and Upright Anglo-Japanese yew (Taxus x media 'Stricta'). These specimens are all over 50 years old and have developed into impressive narrow, upright forms. Another exciting feature of this collection is the amazing exfoliating red-green bark of the 80 year old Hunnewell yew (Taxus x hunnewelliana).
