Chinquapin Oak
Quercus Muehlenbergii

Location in Ontario:
Chinquapin Oak grows throughout the Deciduous Forest Region.


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 (Black, Hill's, Pin, Red, Shumard). White Oaks have leaves with rounded lobes (Bur, White, Swamp White), or simple leaves with sharp teeth (Chinquapin and Dwarf Chinquapin). 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. Oak seeds are acorns; a one-seeded nut with a tough shell and a scaly cup which attaches to the tree. Oaks are monoecious with male (pollen) flowers and female (seed) flowers on the same tree. Oak wood is  favoured for flooring and furniture.

TREE FACT: There's an old saying in reference to the order of leaves coming out in the spring and giving a prediction of the upcoming summer weather:
Ash before Oak, you get a soak,
Oak before Ash, you get a splash.
