Culture
Most filipendulas grow in average, medium to wet, well-drained soil in full sun to part shade. They prefer consistently moist, fertile, humusy soils. Soils must not be allowed to dry out. Appreciates some part afternoon light shade in hot, humid summer climates. Propagate by dividing clumps in fall. Although many filipendulas freely self-seed, it is not known at this time as to whether this new hybrid cultivar will come true from seed. With sufficient moisture, foliage may remain attractive throughout the growing season. If foliage depreciates in late summer, cut back after bloom.
Noteworthy Characteristics
Filipendula is a genus of about 10 or more species of herbaceous perennials from northern temperate areas. Most grow in damp, wet locations but F. vulgaris grows in dry grasslands.
Genus name comes from the Latin words filum meaning a thread and pendulus meaning hanging for the root tubers in some species that hang together with threads.
‘Red Umbrellas’ is a compact, hybrid selection of meadowsweet that features lobed, toothed, lime green leaves with contrasting dark maroon venation. Airy sprays of soft pink blooms are held above the foliage clumps on upright stems from mid-summer to early fall. Excellent for use in fresh cut flower arrangements. Mature plants will reach up to 2.5’ tall and spread to fill a 2’ area.
Problems
No serious insect or disease problems. Many of the filipendulas are susceptible to powdery mildew.
Uses
Border fronts, cottage gardens, wild/naturalized areas, wet meadows or moist areas along streams or ponds. Smaller plants can be massed as a ground cover. Taller plants can be used as accent specimens.
