Faits intéressants
Tall Boneset has upright, branching stems and clusters of small white flowers appearing in late summer and fall. It naturally occurs in dry prairies, open woodlands, roadsides, and fields. It is considerably more tolerant of dry conditions than many other bonesets. Its tall, airy form works well at the back of a native border or in a meadow-style planting. It tolerates dry, poor soils once established. Give it enough space to accommodate its height and branching habit.
