Similar to Quercus montana but obtains a larger ultimate size and is found in moister soils. Common in low areas, river bottoms, swamp borders and ravines. It gained its common name of “Basket Oak” from the baskets created from its wood, and the common name “Cow Oak” from the sweet, edible acorns relished by cows. […]
More tolerant of city conditions than most oaks. […]

This tree gained its specific epithet name, “falcata”, from the sickle-like weapon of the same name, in reference to the sickle-shaped lobes of the leaves. Root disturbance is known […]
‘Redspire’ is one of the better P. calleryana cultivars, with a looser form and somewhat slower growth rate (less prone to limb breakage), but it does have severe fireblight susceptibility. Flowers are malodorous and often killed by late spring freezes. Very small fruits are a litter problem when abundant. Considered invasive in many areas. […]
