Perfect for shady butterfly gardens, Eupatorium purpureum thrives in semi-shade and woodland edges, as well as in full sun. The large pink flowers are a favorite nectar source for Monarchs, Swallowtails and many other butterflies. The textured foliage looks good all summer long. “Sweet Joe” is an excellent, well-behaved garden plant with a shallow fibrous root that won’t interfere with other garden perennials. A great contributor whether massed, naturalized or in the border garden.
Joe Pye Weed Seeds 6935 (Eupatorium maculatum). This is one of our showiest native plants. Joe Pye Weed is another Carolinian Canada species that’s a bee, butterfly and hummingbird favourite. Tall single stemmed plants average 120 cm (4′) height and are loaded with fluffy, vanilla scented, showy purplish-white blooms for several weeks in July and August. Flowers form in terminal domed clusters up to 30 cm (12″) wide. A good wetland meadow plant as it tolerates constantly moist soils – also found along stream banks and marsh edges. Best in full sun but it will tolerate part shade. Perennial hardy to Zone 3.
4,400 seed/gram. Start seed indoors in a soil-less medium any time in late winter. Barely cover seed, moisten the growing medium and then place the container in a fridge or freezer for 3-4 weeks before bringing it back into the warmth. Keep at 15 C (60 F) for the 20 to 30 day (sometimes longer) germination period. After germination, grow on under lights at the same temperature then harden off and transplant outside to a sunny site with moist soil. Better yet, sow directly outdoors in mid-October in the site where it is to grow. This will allow dormant seed to be naturally stratified during the winter. This plant is slow growing and requires two years to flower when grown from seed.

HOW TO GROW
Life Cycle: Perennial
Uses: Attracts Pollinators, Attracts Honeybees, Attracts Butterflies, Aromatic, Deer Resistant
Sowing: Direct sow in late fall, pressing the seeds into the surface of the soil since they need light to germinate. For spring planting, mix the seeds with moist sand and store in the refrigerator for 60 days before direct sowing. To start indoors, scatter the seed on the surface of the soil in a flat; compress the soil slightly and keep it lightly moist until germination, which is naturally slow but should take place within 2-3 months. Keep the soil consistently moist, and transplant seedlings as soon as they reach a height of several inches.
