About this plant
Solidago altissima develops upright stems lined with narrow, lance shaped green leaves arranged alternately along the stalks, creating a vertical, leafy framework through the growing season. In late summer into fall, the upper stems branch into broad, arching plumes composed of many small golden yellow flower clusters that open in succession and create a soft cloud of color.
Native to much of North America, the species occurs naturally in prairies, open fields, and roadside habitats. In gardens it contributes seasonal structure to naturalistic plantings, meadow gardens, and wildlife friendly borders, where the abundant flowers support pollinators and bring warm color late in the season.

Companion plants

Design tip
Late flowers extend the season, so set it behind or beside plants that finish in midsummer. In full sun it holds its shape best, and grouping several together keeps the color strong enough to be seen from across the garden.
