Northern Catalpa

Catalpa speciosa

Summary ⁴

Catalpa speciosa, commonly known as the northern catalpa, hardy catalpa, western catalpa, cigar tree, catawba-tree, or bois chavanon, is a species of Catalpa native to the midwestern United States.

Catalpa speciosa is a medium-sized, deciduous tree growing to 15–30 meters tall and 12 meters wide. It has a trunk up to 1 m in diameter, with brown to gray bark maturing into hard plates or ridges. The leaves are deciduous, opposite (or whorled), large, heart shaped, 7 - 12 in long and 6 - 8 in broad, pointed at the tip and softly hairy beneath. The leaves generally do not color in autumn before falling, instead, they either fall abruptly after the first hard freeze, or turn a slightly yellow-brown before dropping off. The flowers are 1 - 2 1/2 in across, trumpet shaped, white with yellow stripes and purple spots inside; they grow in panicles of 10-30. The fruit is a long, thin legume-like capsule, 20–40 cm long and 10–12 mm diameter; it often stays attached to tree during winter (and can be mistaken for brown icicles). The pod contains numerous flat, light brown seeds with two papery wings.
