White Oak vs Northern Catalpa (Cigar Tree)
Catalpa speciosa
Quercus alba
Northern Catalpa is a striking feature tree with showy flowers, and very large leaves. Its orchid-like flowers are white with yellow and purple accents, and they have a pleasant fragrance. They bloom from late spring to early summer and can last up to two weeks, attracting hummingbirds and pollinators. The leaves are very large, ranging from 15-30 cm long, 12-20 cm wide, forming a canopy that makes it a good shade tree.
They can tolerate dry conditions as well as standing water, air pollution, and salt. These factors and its beauty contribute to its growing popularity as both a boulevard and ornamental tree in colder areas.
Northern Catalpa produces long bean-like capsules and are sometimes called the Cigar Tree in reference to this fruit.
White Oak is large, long-lived tree with an irregular trunk divided into spreading, often horizontal, stout branches. A highly adaptable tree, White Oak features green acorns and beautiful green leaves that turn red-purple in the fall.
With a huge growth in bourbon and scotch over the past few decades there is an emerging shortage of white oak that is the primary tree used for cask barrels and aging.
Note: Most Oak species can be considered toxic for many animals.
