OSC Seeds Butterfly Weed Pkg.

Approx. 30 seeds/pkt (125 seeds/gram)

Bright, sun-loving plants are filled with brilliant orange flower clusters, 10 cm across, from June through to September. Mound-shaped plants average 60 cm tall. Like its name suggests, this beautiful plant is a favourite of butterflies and other nectar-loving insects. Butterfly Milkweed is a native Ontario perennial wildflower that is very heat and drought-tolerant and an excellent choice for the low-maintenance garden. Hardy to Zone 3. For many native and perennial plants, late fall is the best time to sow seed directly outside. Why, you ask? Simply put, many of these plants produce seed that is viable but dormant. This means allowing seeds to naturally stratify over winter will “wake up” the dormant seed for best results.

Sow seed indoors in a soil-less mix in early March for late summer flowering in the first year. Growing medium temperature should be about 20° C. After germination, grow on under lights at a cooler temperature of 15° C before hardening off and planting out to a sunny site after the danger of frost has passed. Dormant fall seeding in mid-October is also a good way to start not only this plant, but many other perennials. Late fall seeding allows any dormant seed to be naturally stratified over the winter. Germination occurs in 10-20 days.
