American Basswood 'Boulevard'
FamilyMalvaceae
Tilia americana 'Boulevard' is a columnar American linden, prized for its narrow, dense, and uniformly upright habit, perfect for urban alignments, tall informal hedges, or formal gardens with limited space. Its large, cordate, very ornamental dark green foliage turns a golden yellow in autumn, adding beautiful seasonal interest. This cultivar is distinguished by its tolerance to salt, pollution, and urban soils, while maintaining a regular shape without excessive pruning. In summer, it produces fragrant, nectar-rich pale yellow flowers, much appreciated by pollinators. 'Boulevard' combines a structured form, generous foliage, and high adaptability, making it ideal for tall, vertical, and elegant plantings.
