Lesser Snakeroot
Ageratina aromatica
Lesser Snakeroot, distinguished by its aromatic leaves, forms a compact mound that becomes covered with tiny, fluffy white flowers in the autumn. This late bloomer is particularly valuable in extending the garden's interest into the cooler months and supporting pollinators when other food sources are scarce. Its fragrance can be a pleasant addition along walkways or in patio areas where it can be easily appreciated.

Maintenance Tips
- Prefers consistent moisture; water regularly, especially in dry spells.
- Cut back in late winter to early spring to promote fresh, vigorous growth.
- Thrives in rich, well-drained soil; mulch annually to retain moisture and suppress weeds.
- Divide every 3-4 years to rejuvenate plants and ensure healthy clusters.
- Optional Chelsea chop in late spring can control growth and delay blooming for a more compact form.
