Description

The Splendid Astilbe is the queen of moist partial shade. From June to August its feather‑light flower plumes in white, pink, salmon and deep red hover over finely feathery, often bronze‑colored spreading foliage. It is the ideal companion for ferns and ferns at the edge of trees or pond banks and remains attractive after flowering with its rust‑brown seed heads.

Care instructions

Plant it in humus‑rich, consistently moist soil in partial shade; it does not tolerate drought, otherwise the leaf margins turn brown. Water abundantly during hot weeks and mulch around the root zone to retain moisture. Divide the clump every three to four years in spring, because it tends to push upward out of the ground over time. Leave the seed heads standing as structure over winter.
