Have you seen the catalpa trees blooming? Most northern catalpas grow to heights of 60 feet, and in the late spring are filled with wonderful white blossoms.

Are there male and female catalpa trees?

Answer: From what I've read, catalpa trees contain both male and female features/'parts' and catalpa trees are best described as being both male and female. The flowers are typically pollinated by insects that are attracted by its flowers and their nectar.

At what age do catalpa trees flower?

While flowers don't emerge on a Southern catalpa until the tree itself is at least 7 years old, the seedpods don't mature until age 10. New seedpods are produced every two to three years, which should alert you to the age of your tree, especially if it's the first time this occurs.
