Notes: White Mistflower is valued for its profuse, fragrant white blooms that provide essential nectar for pollinators late in the season.

It tolerates drought, heat, and neglect, making it an excellent choice for xeriscaping or low-maintenance landscapes. Pruning after flowering helps maintain its shape and encourages dense growth.
