Hardy Ageratum, a North American native, is a delightful addition to any garden. Its clusters of fluffy, lavender-blue flowers bloom from late summer to fall, attracting butterflies and bees, which are essential for pollination. This perennial is not only beautiful but also low-maintenance, thriving in various soil types and resisting deer. Its ability to spread quickly makes it perfect for ground cover, helping to prevent soil erosion and support local ecosystems.
