Ivory Pillar Japanese Lilac Tree

Ivory Pillar Japanese Lilac Tree (Syringa reticulata 'Willamette')

Ivory Pillar Japanese Lilac Tree (Syringa reticulata 'Willamette') is a columnar flowering tree celebrated for its vertical form, creamy white blooms, and urban resilience. Also known as Willamette Japanese Tree Lilac, this cultivar brings late-spring interest and strong architectural structure to landscapes with limited horizontal space.

Distinctive Features

This narrow, upright selection matures to 20 to 25 feet tall and 6 to 10 feet wide, making it ideal for tight spaces or as a vertical accent. In early summer, it produces large, fragrant panicles of ivory-white flowers above dark green foliage. The bark is reddish-brown and exfoliates with age, adding winter interest. Its shape is more columnar than typical Japanese Tree Lilacs, offering a tidy, formal look even when not in bloom.
