Chinquapin Oak, Long Point, Norfolk County

Genus Quercus
The ten Oaks of Southern Ontario are divided into two categories. Red Oaks have lobed leaves which are pointed and acorns (seeds) that develop over two years. White Oaks have leaves with rounded lobes or simple leaves with sharp teeth and acorns (seeds) that develop over one year. Acorns are a one-seeded nut with a tough shell, and a scaly cap which attaches to the tree. Often, Oak leaves stay on the tree over winter. Oak leaves on the ground are slow to decay, as this is a survival strategy to prevent the growth of other plants nearby. Oaks are monoecious with male (pollen) flowers and female (seed) flowers on the same tree. Oak is a favoured wood for flooring and furniture.
