Catalpa speciosa was originally thought to be native only to a small area of the midwestern United States near the confluence of the Mississippi and Ohio Rivers.However, in 1976, investigation of an archeological site of an island in West Virginia's portion of the Ohio River revealed Catalpa speciosa to be present on the island around the period of 1500-1700 CE.
Most Catalpa are deciduous trees; they typically grow to 12–18 metres (40–60 ft) tall, with branches spreading to a diameter of about 6–12 metres (20–40 ft). They are fast growers and a 10-year-old sapling may stand about 6 metres (20 ft) tall. They have characteristic large, heart-shaped leaves, which in some species are three-lobed.

Catalpa ovata, the yellow catalpa[1][5] or Chinese catalpa[1] (Chinese: 梓; pinyin: zǐ), is a pod-bearing tree native to China. Compared to C. speciosa, it is much smaller, typically reaching heights between 20 and 30 feet (6 and 9 m). The inflorescences form 4–10-inch-long (100–250 mm) bunches of creamy white flowers with distinctly ...
