Faits intéressants
Butterfly Milkweed is well suited for sunny, dry locations and performs best in well-drained soils, making it ideal for borders, and prairie-style plantings. It adds vibrant colour to mid-summer gardens. Unlike other milkweeds, it does not spread aggressively, forming neat clumps that are easy to manage in smaller garden spaces. It is a valuable plant for pollinators, attracting butterflies, bees, and other beneficial insects with its bright orange summer flowers.
