Ageratina havanensis (Shrubby Boneset)
Shrubby boneset provides a lovely splash of white blooms in the fall, adds structure to perennial gardens and has tremendous wildlife value. It should not be hedged, but instead let grow naturally, and trimmed back late winter to promote more blooms (since it blooms on new wood) and have a fuller plant. Shrubby boneset is adaptable and will grow in most soils as long as it is provided good drainage. It is drought tolerant and works well in sun to part shade. Bright woodland edge is ideal for this plant. It does best when it is trimmed by about one third each year.
Shrubby boneset attracts a lot of pollinators, such as hummingbirds, moths, butterflies, bees, and more. It is a must-have in a pollinator garden or any wildscape.
