Description
Astilbe ‘Montgomery’ – This clump forming perennial is a descendant of A. japonica grows up to 28” tall and spreads to 18” wide. It produces finely cut, dark red-bronze foliage. In mid summer it bears tapering panicles of deep red flowers.
Grow in moist fertile, humus rich soil or boggy sites in full sun, or in drier soils in lightly shaded areas and don’t allow it to dry out. They dislike alkaline or clay soil that dries out. Divide in spring or winter when dormant every 3 or 4 years to maintain vigor and flower quality and remove and discard old woody rhizomes.
