What Is a Catalpa Tree and Why Should You Plant One?
What Is a Catalpa Tree?
A catalpa tree, scientifically known as Catalpa speciosa, is a medium-sized deciduous tree native to the midwestern United States near the confluence of the Mississippi and Ohio Rivers.
It has several common names including Northern catalpa, hardy catalpa, western catalpa, cigar tree, and catawba.
Catalpa trees grow to a height of 15-30 meters with a width of 12 meters and have a trunk diameter of up to 1 meter.
The bark is brown to gray and turns into hard plates or ridges.
The leaves are deciduous, heart-shaped, and softly hairy beneath.
They do not color in autumn before falling and are the last to grow in spring.
The flowers are trumpet-shaped, white with yellow stripes and purple spots, and grow in panicles of 10-30.
The fruit is a long, thin legume-like capsule that stays attached to the tree during winter.
Catalpa trees are widely planted as ornamental trees and are adaptable to moist, high pH soil and full sun.
They can grow almost anywhere in North America and have various uses, including as a tonewood in guitar-making.

Did You Know?
1. The catalpa tree, also known as “the fisherman’s friend,” is said to be a good indicator of nearby fishing spots. If you spot a catalpa tree along a river or lake, it’s believed that the presence of catalpa worms on its leaves indicates a flourishing fish population.
2. Catalpa trees have been used for medicinal purposes by Native American tribes for centuries. They made tea from the inner bark of the tree to alleviate symptoms of asthma, bronchitis, and various respiratory conditions.
3. Catalpa trees are sometimes called “Indian cigars” due to the long, cylindrical shape of their fruit pods. In the fall, these pods turn dry and brown, resembling a cigar, making for an interesting visual resemblance.
4. The wood of catalpa trees is commonly used for making musical instruments, particularly acoustic guitars. The lightweight and low-density wood of this tree species can produce a rich and resonant tone.
5. Catalpa trees are hosts to the caterpillar of the catalpa sphinx moth. These large moths are known for their unique defense mechanism – when disturbed, the caterpillar emits a foul-smelling substance that can deter predators.
Description Of Catalpa Speciosa
The Catalpa speciosa, commonly known as the Northern catalpa or Hardy catalpa, is a medium-sized deciduous tree. It can reach heights of 15-30 meters with a width of 12 meters. The trunk of this tree can have a diameter of up to 1 meter and is covered in brown to gray bark that transforms into hard plates or ridges as the tree matures.
The leaves of the Catalpa speciosa are deciduous and heart-shaped. They measure around 20-30 cm in length and 15-20 cm in breadth. The leaves are softly hairy beneath and do not change color in autumn before falling. Interestingly, this tree is the last to grow leaves in spring. The winter twigs of the Catalpa speciosa display sunken leaf scars that resemble suction cups.
The flowers of the Catalpa speciosa are trumpet-shaped and grow in panicles of 10-30. These flowers are white with yellow stripes and purple spots. They measure around 3-6 cm across.
The fruit of this tree is a long, thin legume-like capsule. It reaches lengths of 20-40 cm with a diameter of 10-12 mm. What’s unique about the fruit is that it stays attached to the tree throughout the winter. Inside the capsule, numerous flat, light brown seeds with two papery wings can be found.

Distribution And Range Of The Catalpa Tree
The Catalpa speciosa is a tree species that is native to the midwestern United States, specifically near the confluence of the Mississippi and Ohio Rivers. It was initially discovered on an island in West Virginia’s portion of the Ohio River between the years 1500 and 1700 CE. Since then, the range of the Catalpa speciosa has gradually expanded east of the Rocky Mountains, extending beyond its original location. Today, this tree species can be observed growing in diverse regions across North America.
Cultivation And Uses Of The Catalpa Tree
The Catalpa speciosa is a widely planted ornamental tree known for its aesthetic appeal. It thrives in moist, high pH soil and full sun, making it adaptable to various environments in North America. Notably, it has received the Royal Horticultural Society’s Award of Garden Merit in the UK, affirming its desirability as a landscaping choice.
The wood of the Catalpa tree is soft and lightweight, with a weight of approximately 26 pounds per cubic foot when dry. Its resistance to rot is another advantageous characteristic, making it suitable for various applications. Common uses include fence posts, furniture, interior trim, cabinetry, and even railroad ties (although less successfully). Compared to other hardwood species in the United States, Catalpa wood has low shrinkage/expansion rates, making it a valuable material for construction.
Despite its numerous advantages, the Catalpa tree is sometimes considered a weed tree in certain areas, and its potential as a wood source is often under-appreciated. However, it continues to be popular among fishing enthusiasts due to the caterpillars it attracts, which serve as excellent bait.

Considerations And Benefits Of The Catalpa Tree
The Catalpa speciosa can occasionally experience minor diseases and pests, but it does not pose a significant threat to other trees in its vicinity. Furthermore, this tree provides shelter for many species of birds, making it an essential component of wildlife habitats. Its large size and dense foliage offer ample protection and nesting opportunities for avian creatures.
Another notable benefit of the Catalpa tree is its use as a tonewood in guitar-making. The wood of this tree is highly sought-after by luthiers for its tonal qualities. It produces a warm and resonant sound, making it a preferred choice for acoustic guitar backs and sides.
Catalpa As A Tonewood In Guitar-Making
The Catalpa wood has valuable tonal properties that make it highly desirable for guitar manufacturing. Luthiers carefully choose quarter-sawn sections from the tree to create the backs and sides of acoustic guitars. The wood’s resonance produces a rich and balanced sound, making it a favorite among musicians. Notably, its versatility extends beyond acoustic guitars and can also be used in other stringed instruments.
The Catalpa speciosa, commonly known as the Northern Catalpa or Hardy Catalpa, is a medium-sized deciduous tree native to the midwestern United States. Its adaptability to various environments and unique characteristics make it an excellent choice for landscaping purposes. Additionally, the durability and tonal properties of Catalpa wood have made it widely used in various industries, including construction and guitar-making. By planting a Catalpa tree, you can enhance the aesthetics of your surroundings while providing habitat and other benefits for birds and wildlife.
