The Story

Plant Bio

American linden, or basswood, is a large native deciduous tree with a dense canopy of heart-shaped leaves and highly fragrant summer flowers. 'Boulevard' is a cultivar chosen for its narrow, pyramidal form and ascending branches, making it well-suited for avenues and areas where a broad canopy is not desired.

EarlyLate

Uses & Benefits:

A handsome and stately tree, 'Boulevard' offers a formal, pyramidal shape that is neater than the species. Its large, heart-shaped leaves create dense shade, and the fragrant, creamy-yellow flowers in early summer are a delightful sensory feature.

Its narrow habit makes it an excellent choice for lining streets, boulevards, and driveways where a large, spreading canopy is not feasible. It serves well as a tall screen or windbreak when planted in a row.

The flowers are a vital nectar source for honeybees, producing a prized, flavorful honey. The tree is a host plant for the larvae of several moth species and provides shelter and nesting sites for birds.

Planting

How to Grow

Choose a site with full sun and moist, well-drained soil.
Dig a hole twice as wide as the root ball and just as deep.
Place the tree in the hole, ensuring the root flare is at or above soil level.
Backfill with native soil, watering halfway to settle.
Finish backfilling and create a small water-retaining berm.
Water thoroughly and apply a 3-inch layer of mulch.

Pro Tip

Water deeply and regularly during the first few years to establish a strong root system for this large, fast-growing tree.
