June Native Plant of the Month - Linden Tree
What Is That Sweet Smell in Chicago Right Now?
Meet the American Linden Tree
There are few native trees more beloved in early summer than the American Linden, also known as American Basswood (Tilia americana). While many trees capture attention with showy flowers, the Linden earns admiration in a different way, with one of the most intoxicating fragrances found in the Midwest landscape.
Every June, people throughout Chicago and the surrounding suburbs ask the same question:
"What is that amazing sweet smell?"
More often than not, the answer is a blooming Linden tree.
Native to Illinois and much of eastern North America, the American Linden is a magnificent shade tree that supports pollinators, provides cooling summer shade, and fills neighborhoods with a honey-like fragrance that signals the arrival of summer.
What Does an American Linden Look Like?
The American Linden is a large deciduous tree known for its broad canopy and distinctive heart-shaped leaves. Mature specimens can reach 60–80 feet tall and develop a graceful, rounded form that makes them excellent shade trees for larger residential properties, parks, and streetscapes.
In June, clusters of small pale yellow flowers emerge beneath the leaves. While the flowers themselves are relatively modest, their fragrance is anything but. The sweet scent can travel surprising distances, attracting both people and pollinators alike.
Throughout the growing season, Linden trees provide dense green foliage and welcome shade, helping cool homes, patios, and outdoor living spaces during Chicago's warmest months.

Wildlife & Pollinator Benefits
The American Linden is often considered one of the most important nectar-producing native trees in North America.
When it blooms, the canopy comes alive with native bees, honeybees, butterflies, and other beneficial insects gathering nectar from the fragrant flowers. Many beekeepers consider Linden bloom season one of the highlights of the year, and Linden honey is prized for its delicate floral flavor.
Beyond pollinators, Linden trees also support numerous native insects that contribute to a healthy food web for birds and other wildlife.
