Northern Catalpa Catalpa speciosa Part of the northern catalpa’s scientific name, speciosa, is Latin for “showy.” And at first glance, it’s clear to see why. Everything about this tree is visually interesting — from its large, heartshaped leaves to its white, trumpetshaped flowers. It’s also hardy and grows quickly. Those winning qualities have led it to become one of the most popular shade trees in the United States.
FLOWERS: Large, white, trumpetshaped, and mildly fragrant. Its petals feature yellow and purple lines and spots.
FRUIT: Bean-like pods, 8–20 inches long and ¼–½ inch wide. The pods start off green and turn brown when ripe.
FORM: Oval-shaped and large, reaching 60 feet tall at maturity. Can develop a unique twisting trunk and branches.

LEAVES: Heart-shaped and distinctively large, reaching up to 12 inches in length and 8 inches in width. Fall foliage is yellow or brown.
BARK: Grayish-brown, breaking into large, scaly plates or ridges with age.
WILDLIFE VALUE: The northern catalpa is the sole host of the catalpa sphinx moth. It is also popular with honeybees and hummingbirds.
