American Basswood (Tilia americana)

🌳 Species Overview

American Basswood is a majestic native hardwood prized for its broad, heart-shaped leaves, fragrant summer flowers, and stately, symmetrical form. Found throughout eastern North America, this species is beloved by pollinators, woodworkers, and landscape designers alike. Its combination of fast growth, deep shade, and exceptional wildlife value makes it one of the most versatile native trees you can plant.

🌼 Seasonal Interest

• Spring: Large, soft green leaves emerge early, creating a lush canopy.
• Summer: Creamy-yellow, sweetly fragrant flowers attract bees in huge numbers—Basswood honey is famous for its clarity and flavor.
• Fall: Foliage shifts to warm yellow tones; seed bracts add subtle ornamental texture.
• Winter: Strong branching structure and pale gray bark provide winter interest.

🌱 Growth Habit & Size

American Basswood grows rapidly once established, often adding 1–2 feet per year in good conditions. Mature trees reach:

• Height: 60–80 ft
• Spread: 30–50 ft
• Form: Upright, oval to rounded crown with dense foliage

This makes it an excellent choice for shade, windbreaks, or anchoring large landscapes.

🌿 Ecology & Benefits

• Pollinator magnet: One of the best native nectar sources for bees.
• Wildlife support: Seeds feed birds and small mammals.
• Soil improvement: Leaf litter enriches soil with calcium and organic matter.
• Native resilience: Handles urban conditions, road salt, and a wide range of soils.

American Basswood thrives in:

• Sun: Full sun to light shade
• Soil: Moist, well-drained loam preferred, but adaptable to clay or sandy soils
