The Catalpa is a stately, flowering, ornamental tree that typically grows 40 to 60 feet tall. At maturity, the spread will extend 20 to 40 feet.
The crown of the tree is rounded with large, heart-shaped leaves that can grow to about a foot long. In fall these green leaves will change to a yellowish-green to yellowish-brown color.
The tree’s main feature is its beautiful, bell-shaped white flowers with yellow and purple markings that appear in late spring/early summer. After the petals fall, a seed pod, approximately 8 to 20 inches long and ½ inch wide, remains. The pods resemble the shape of cigar, leading to the trees frequently being called “cigar” trees. Flowers will typically not appear until a tree is 15 years old.
Catalpas can grow in sun or partial shade areas. Soil should be well-drained, moist and rich. The tree has a moderate to fast growth rate and can tolerate dry, clay and alkaline soil, and withstand hot environments. Hardiness Zone: 4-8.
