Corylus avellana, the common hazel, is a species of hazel native to Europe and western Asia, from the British Isles south to Iberia, Greece, Turkey and Cyprus, north to central Scandinavia, and east to the central Ural Mountains, the Caucasus, and northwestern Iran.
Although the early spring flowers are beautiful and the fruit is attractive, the Pyrus communis is normally grown only for its fruit crop and not as an ornamental.
Owing to its name, the Fragrant Granadilla has very fragrant flowers. The flowers are spectacular, 7-10 cm wide, the corona filaments variegated with red, white and purple.
