The flowers are wind-pollinated catkins. The fruit is an acorn, maturing about 18 months after pollination, 2-3 cm long and 2 cm broad, bicoloured with an orange basal half grading to a green-brown tip; the acorn cup is 1.5-2 cm deep, densely covered in soft 4-8 mm long 'mossy' bristles. The acorns are very bitter, but are eaten by jays and pigeons; squirrels usually only eat them when other food sources have run out. Look up flower in Wiktionary, the free dictionary. ...

Cultivation and uses

Sawtooth Oak is widely planted in eastern North America and is naturalised in some areas; it is also occasionally planted in Europe but has not naturalised there. Most planting in North America was carried out for wildlife food provision, as the species tends to bear heavier crops of acorns than other native American oak species; however the bitterness of the acorns makes it less suitable for this purpose and Sawtooth Oak is becoming a problem invasive species in some areas. The wood has many of the characteristics of other oaks, but is very prone to crack and split and hence is relegated to such uses as fencing.
