Joe Pye Weed Seeds - Queen of the Meadow


Eupatorium purpurea

Joe Pye Weed is a butterfly magnet! This first-year flowering perennial produces spectacular blooms in summer and early fall. Enormous 18” heads of fragrant, mauve blossoms attract swarms of pollinators and make long-lasting cut flowers for your table. Plants grow 5-7' tall, but if you'd like to keep them shorter, cut back half the height in mid-June to encourage bushier regrowth.  Seeds need to be cold stratified for best germination. Note that Joe Pye Weed tends to emerge later in the spring, so don't be discouraged if you sow your seeds in the fall and don't see them growing first thing in the spring. Full sun.

Bed Preparation


Joe Pye Weed is very adaptable and will naturalize readily. Choose a site with full sun to partial shade.




Seeds need a period of cold, moist conditions for optimal germination. Direct sow outdoors in fall or stratify seed in a refrigerator for 8-12 weeks before sowing. Sow seeds ¼" deep and 4-6" apart. Seeds will sprout in 10-21 days. Thin seedlings so that mature plants are 12" apart.

Keep adequately moist for first year until plants become well established. Somewhat drought tolerant once established.




Harvest for cut flowers anytime, or leave for the pollinators!

Seed Saving


Joe Pye Weed is a hardy perennial whose seed matures in late summer/fall. Seed is ready to harvest when dry and brown. Store seeds in a cool, dry place. Seeds are viable for 5-7 years.
