Hollow Joe Pye Seeds / Eutrochium fistulosum
Hollow Joe Pye is the giant among Joe Pye species, reaching up to 10 or more feet in moist soil conditions that it favors, with a dome of small pink flowers that draw butterflies and bees like a magnet. It can handle standing water for brief periods, so would work well in a rain garden. Because it can grow so tall, it can also work well at the back of borders or at the center of an aggregation of plants.
Its common name relates to its hollow stems, which are often streaked with purple and, like the other Joe Pyes features whorled leaves arranged in a circular pattern at the same point on the stem. From its size and hundreds of beautiful flowers, it is definitely one of the most memorable plants native to eastern North America.

Seed Planting/Germination Key
Storage: Store in a cool, dry, dark place prior to planting.
Rule of thumb for depth of planting: The maximum depth should generally be half the width of the seed, but many wildflower seeds will germinate well if sown on the surface.
Easy: Generally germinates within 5 to 30 days with no need for cold pretreatment. Keep potting mix or soil consistently moist during the germination period.
Cold(30): Germination rates are higher if cold pretreatment applied either by placing the seed within moist paper towel or sand within a refrigerator for 30 days or outside in late winter.
Cold(60): Germination rates are higher if cold pretreatment applied either by placing the seed within moist paper towel or sand within a refrigerator for 60 days or outside in mid-winter.
Cold(90); Outdoors: Germination rates are higher if cold pretreatment applied either by placing the seed within moist paper towel or sand within a refrigerator for 90 days or outside in late fall or early winter. The best route is to plant these outdoors in either a pot or directly on the soil.
