The Twisted Catalpa: A Local Tree with a Story to Tell

On the grounds of the Lincoln Public Library stands a tree that rarely goes unnoticed. Its trunk spirals upward in thick, rope-like ridges, as though shaped by a patient hand over decades. At first glance, many observers—myself included—have mistaken it for a black locust, drawn in by the deeply furrowed bark and dramatic twisting form. But a closer look, especially in late fall and winter, reveals the truth.

Hanging from its branches are long, slender seed pods—often a foot or more in length—swaying like narrow ribbons in the wind. These “cigars,” as they are sometimes called, unmistakably identify the tree as a Northern Catalpa (Catalpa speciosa).

A Tree with Character—and History

According to Lincoln Public Library records, this catalpa was planted in the early 1900s and quickly became a fixture of the grounds. Its unusual twisting trunk has inspired decades of curiosity. Was it shaped by vines? Did multiple trees fuse together over time?

Arborists have since settled the matter: this is a single tree. The twisting, they suggest, is likely due to a genetic anomaly, possibly influenced by environmental factors such as light or underground obstacles affecting root growth. Whatever the cause, the result is a living sculpture—one that tells a story written slowly in wood.

Recognizing the Northern Catalpa

Beyond its striking trunk, the Northern Catalpa has several distinctive features:

• Leaves: Large, heart-shaped, and soft, often 6–12 inches across
• Flowers: Showy white blossoms in late spring, marked with purple spots and yellow streaks
• Seed Pods: Long, thin, bean-like pods (8–20 inches) that persist into winter
• Form: An open, irregular crown, often with a slightly wild appearance

These traits make the catalpa both ornamental and memorable—especially when in bloom.

Cultural and Practical Uses

The name “Catalpa” is derived from a Native American term, often rendered as kutulpa. Historically, parts of the tree have been used in herbal remedies. Teas made from seeds or bark were believed to treat ailments ranging from bronchitis to snakebites, though such uses are largely anecdotal today.

The wood itself is valued for its resistance to rot and has even been used as tonewood in instruments—a reminder that this tree’s contributions extend beyond its visual appeal.

Looking Ahead

Recognizing the uniqueness of this specimen, the Lincoln Garden Club, in collaboration with the Arnold Arboretum, has undertaken efforts to propagate new catalpas with similar twisting characteristics. Through cuttings, seeds, and grafting, they hope to preserve not just the species, but the singular personality of this tree.

Because eventually, even the most storied trees reach the end of their lives.

A Living Landmark

The twisted catalpa is more than a botanical curiosity—it is a quiet landmark, a conversation starter, and a testament to the unpredictability of nature. It reminds us that even familiar species can surprise us, and that sometimes the most interesting stories are rooted right in front of us.

Next time you pass by, look up. The pods may be rattling softly overhead, and the trunk—still turning, still reaching—will be there, as it has been for over a century.
