Monarch butterflies (Danaus plexippus) only lay eggs on plants in the milkweed family. The Milkweed host-plants are the only food Monarch caterpillars eat. Milkweed is no longer listed as an Ontario noxious weed.  Do not consume any part of a milkweed plant as the sap contains cardiac glycosides that are poisonous to humans and livestock, if ingested in significant quantities. Flowers are attractive, fragrant and extremely popular nectar and pollen sources for pollinators (bees in particular). Grows 60-90 cm in height. Perennial 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.
