ISO quercus alba

White Oak is a long-lived, slow-growing tree, reaching 60 to 100 feet in height with a spread of 50 to 90 feet in its native bottomland soil. Old specimens can be massive, growing to be several hundred years old. The red fall color is fairly reliable year to year and is outstanding among the oaks in USDA hardiness zones 8a and colder areas. Brown leaves may be held on the tree into the early part of the winter.–Gilman and Watson

According to the USDA’s Woody Plant Seed Manual, quercus is the largest genus of trees native to the United States and was designated as the “national tree” by the National Arbor Day Foundation in 2004. White oaks typically don’t bear acorns until their twentieth year. The large seedcrop years are spaced out, every four to ten years.
Nurseries don’t do much of a job propagating these.

This time last year I had twenty of these juveniles in pots; this year I haven’t been able to find a single acorn. I’ve checked in four counties and bicycled to neighborhoods in Charlottesville looking for acorns where they are typically plentiful. No joy. The New York Times has story noting the smallest acorn crop in 20 years.
