Boneset (Eupatorium perfoliatum) is a native North American perennial of wet meadows and stream banks, recognized by opposite leaves fused around the stem (perfoliate) and flat-topped clusters of white fuzzy flowers in late summer and fall. Plants typically grow 60–120 cm (2–4 feet) tall with a bushy, upright habit. 🌞💧 Sun and Water Requirements: - Full sun to light shade. - Rich, moist to wet soil; tolerates seasonal saturation. In subtropical and tropical Americas, grow in rain gardens, pond buffers, or heavily mulched beds with steady irrigation—dry sand will cause wilting and poor bloom. - Airflow helps foliage during humid wet season. ✂️ Methods to Propagate: - Seeds: Surface-sow in fall or stratify moist cold 4–6 weeks; germinates in warm, moist conditions. - Division: Split fibrous clumps in early spring; replant at the same depth and water well. 🌾 Harvest / Best Use Timing: - Gather flowering tops at full bloom on dry mornings for drying; traditional use focuses on aerial parts. Leave late flowers for migrating pollinators.
