Boltonia asteroides var. latisquama

Boltonia asteroides var. latisquama is a robust herbaceous perennial member of the Asteraceae family. Commonly known for its late-season bloom, this plant provides a cloud of daisy-like flowers that bring texture and color to the landscape when many other summer flowers begin to fade.

Native to North America, this species naturally inhabits moist meadows, prairies, and riparian zones. Its evolutionary history in these diverse environments has made it a versatile plant for garden cultivation, provided that its basic moisture requirements are met during the active growing season.

Botanically, the plant features tall, branched stems that typically reach heights of 3 to 5 feet. The foliage is lanceolate and grayish-green, providing a subtle backdrop to the profusion of white to lavender-pink blooms that appear from late summer through early autumn. The flowers are characterized by their small, numerous heads with prominent yellow centers.

For optimal growth, this crop requires full sun and consistently moist, fertile soil. While it is adaptable to different soil types, it performs best in loam or clay-loam that retains moisture. Agricultural maintenance involves basic fertilization in early spring and occasional staking if planted in windy, exposed areas to prevent the tall stems from lodging.

• Sun exposure: Full sun
• Moisture needs: Moderate to high; avoid drought stress
• Soil type: Fertile, well-drained but moist
• Hardiness: Fully hardy in most temperate zones
• Pest resistance: Excellent; rarely troubled by diseases

The primary horticultural application for this variety is in ornamental landscaping. It is highly valued for border backdrops, wild-style garden schemes, and moisture-rich planting beds. Because of its structural integrity and late blooming, it is a preferred plant for adding seasonal interest and supporting pollinator populations in autumn gardens.
