Trees of Britain and Europe. Collins . It is a deciduous shrub 6 - tall, with stems up to 20 cm thick. The leaves are rounded, 5 – long by 4–10 cm broad, with a coarsely double-serrated margin. The flowers are wind-pollinated catkins produced in late winter; the male (pollen) catkins are pale yellow, 5–10 cm long, while the female catkins are bright red and only 1–3 mm long. The fruit is a nut produced in clusters of 1–5 together; each nut is 1.5–2.5 cm long, fully enclosed in a 3–5 cm long, tubular involucre (husk).Flora of NW Europe: Corylus maxima The filbert is similar to the related common hazel, C. avellana, differing in having the nut more fully enclosed by the tubular involucre. This feature is shared by the beaked hazel C. cornuta of North America, and the Asian beaked hazel C. sieboldiana of eastern Asia.
