Joe Pye Weed, Hollow

Hollow Joe Pye Weed (Eutrochium fistulosum)
Also known as: Trumpetweed, Hollow-Stemmed Joe Pye, Sweet Joe Pye

Hollow Joe Pye Weed is a towering native perennial that brings bold presence and ecological power to moist meadows, pollinator gardens, and wetland restoration projects. With its hollow, purplish stems and huge domes of dusty pink to mauve flowers, this species is a magnet for monarchs, swallowtails, and native bees during its long blooming season. It thrives in wet soils and naturalized plantings, providing vertical structure and essential late-season nectar.

Key Characteristics

• Vital Late-Season Nectar for Pollinators
  Blooming from July to September, Hollow Joe Pye Weed provides critical nectar during a seasonal gap for bees, butterflies, and moths. It is especially attractive to Monarchs during their fall migration, as well as Eastern Tiger Swallowtails, fritillaries, and native long-tongued bees.
• Host Plant for Moth Species
  Joe Pye Weed serves as a larval host for the Clymene moth (Haploa clymene), Pearl Crescent (Phyciodes tharos), and several species of owlet moths. Its foliage feeds the next generation of pollinators while its flowers fuel the adults.
• Essential Plant for Moist Meadow & Rain Garden Design
  This species is native to wet meadows, streambanks, and lowland woods from eastern Canada to the southern U.S. It thrives in rain gardens, swales, pond edges, and wetland buffers, providing height, habitat, and deep-rooted soil stabilization.
• Tall, Hollow Stems Offer Overwintering Habitat
  The stout, hollow stems stand 6-8 feet tall and persist into winter, offering vital shelter for overwintering insects and nesting sites for native bees. Leave stems standing until spring clean-up to support insect biodiversity.
