Bring late-season color to your garden with Anemone tomentosa 'Robustissima', a classic fall-blooming perennial valued for its airy clusters of mauve-pink flowers held above bold, grape-like foliage. You will enjoy dependable blooms from late summer into fall, when many other perennials are fading, and the flowers also draw butterflies and other pollinators.
Plant it where you can appreciate its height and movement: mature clumps typically reach about 24-36 inches tall and can spread to roughly 24-36 inches wide over time. It performs well in full sun to part shade. In warmer or drier spots, give it afternoon shade and steady moisture for the best flowering and clean foliage.
For best results, grow it in moist, well-drained soil enriched with organic matter. Water regularly during establishment, then keep the soil evenly moist through summer; it can tolerate occasional dry spells once established, but drought can reduce flowering. Deer and rabbits usually leave it alone, making it a strong choice for mixed borders.
This selection can spread by underground growth and gradually fill an area, so place it with room to expand. If you want to control its footprint or share it, you can lift and divide clumps in spring or after flowering. Cut back old stems after frost and watch for late spring emergence.
