Meadowsweet (Filipendula denudata)
Filipendula denudata, or Meadowsweet, is a robust perennial offering showy, fragrant creamy white blooms from July to September.
Complete Plant Information
Overview
Filipendula denudata, commonly known as Meadowsweet, is a standout herbaceous perennial prized for its impressive height and abundant, sweet-smelling flower clusters. Its upright habit and rich foliage make it a fantastic structural element, particularly in wetter sections of the garden where many other perennials struggle. This robust plant delivers low maintenance across its long blooming season.
Native to damp meadows and stream banks in Northern temperate regions, Meadowsweet thrives when provided with consistent moisture. Its aesthetic value comes from the contrast between its finely divided dark green leaves and the airy sprays of creamy white flowers that appear from mid-summer into early autumn. Gardeners appreciate the resilience of Filipendula denudata as it manages deer and rabbits well.
The impressive stature of Filipendula denudata, often reaching six feet, also offers functional benefits, lending itself perfectly to use in informal hedges or naturalized areas. Providing both fragrance in the air and visual interest throughout the summer, Meadowsweet is an excellent choice for large-scale plantings or natural rain garden designs.

How to Grow
Filipendula denudata is easily established in average, medium to wet, well-drained soil. For the best performance, aim for a location that receives full sun, although you should consider providing some part afternoon shade if you are growing this plant in hot summer climates. While it prefers consistently moist, fertile, humusy soils, it is notably more drought tolerant than many other species within the Filipendula genus.
Establishment is straightforward, as this Meadowsweet readily spreads in the landscape through both self-seeding and by its tuberous, spreading rootstocks. If spacing becomes an issue, clumps may be divided carefully in the spring. Maintaining moisture is key; with sufficient water, the attractive foliage will persist throughout the growing season.
Cultural requirements are generally easygoing; this plant prefers soils that are neutral to slightly alkaline. If the foliage begins to look tired or depreciates in late summer, a simple cut-back immediately after the bloom period will encourage rejuvenation and keep the clump looking tidy for next year. This low-maintenance approach ensures the longevity of your Filipendula denudata planting.
Landscape Uses
The versatility of Meadowsweet makes it highly adaptable across several landscape roles. Its height makes it an excellent candidate for informal hedges or as a dramatic background plant in cottage gardens, contrasting beautifully with shorter perennials. Furthermore, its tolerance for moist conditions means Filipendula denudata functions perfectly in naturalized areas, wild meadows, or dedicated rain garden installations beside ponds or drainage areas.
When designing with the airy flower panicles of Filipendula denudata, pair it with plants that appreciate similar wet soil conditions but offer contrasting foliage texture or color, such as hostas or tall astilbes. The foliage itself forms an interesting ground cover at the base of the stems, suppressing weeds when the plant is well-established. Using Meadowsweet in mass plantings enhances its naturalizing effect, mimicking its native habitat.

Noteworthy Characteristics
Filipendula denudata, commonly called meadowsweet or queen-of-the-meadow, is an upright, clump-forming perennial of the rose family that is native to damp meadows, pond peripheries, bogs and along streams and rivers in Europe and western Asia. Foliage consists of finely-divided, dark green leaves, and tiny, fragrant, creamy white flowers bloom in branched, astilbe-like, terminal panicles. The leaves offer an almond-like aroma, while the flowers possess a sweet smell.

- Deer
- Erosion
Potential Problems
Filipendula denudata generally exhibits few serious insect or disease complications in the landscape, which contributes to its low maintenance requirement. The primary concern gardeners might encounter is susceptibility to powdery mildew. This fungal issue usually appears as white, dusty growth on the leaves, often exacerbated by high humidity combined with poor air circulation or inconsistent moisture levels. Ensure adequate spacing between plants to promote airflow, and water the soil directly rather than spraying the foliage, especially late in the day.
Frequently Asked Questions
What hardiness zones is Meadowsweet suitable for?
Filipendula denudata is reliably hardy across USDA Zones 4 through 8. Confirming your zone is the first step before planting.
How large does Meadowsweet grow?
This vigorous perennial typically reaches mature heights between 3 and 6 feet tall, with a similar spread of 3 to 6 feet, forming substantial clumps.
When does Filipendula denudata bloom?
Meadowsweet produces its signature creamy white blooms from July through September, providing much-needed late-season color and fragrance.
What sun exposure does Filipendula denudata need?
This plant performs well in full sun but benefits from some afternoon shade when grown in very hot summer locations, preferring full sun to part shade overall.
Conclusion
The combination of easy culture, impressive height, and fragrant, showy blooms makes Filipendula denudata an invaluable addition to any garden needing vertical interest in moist conditions. By ensuring consistent water availability, you can enjoy the reliable performance of this Meadowsweet variety year after year. Check your local USDA zone compatibility and plan to install this robust perennial during spring or fall planting windows.
Propagation Tips
Division is the most common and successful method for propagating Filipendula denudata. Because the plant spreads via tuberous rootstocks, it is best handled in the early spring just as new growth is emerging. Carefully dig up the entire clump and then use a sharp spade or knife to divide the root mass into sections, ensuring each new division has several healthy buds attached. Replant the sections immediately at the same depth they were previously growing.
While Filipendula denudata can sometimes self-seed, collecting and sowing seeds results in variable offspring and is less reliable than vegetative division. If you do choose to collect seed, ensure they are fully mature, and sow them in pots filled with moist, well-drained soil in the autumn for germination the following spring.
Wildlife Benefits
The flower clusters of Meadowsweet are attractive to various beneficial insects throughout their summer bloom period. The tiny, fragrant flowers offer accessible nectar and pollen resources favored by small bees and beneficial wasps. While deer and rabbits tend to avoid the foliage, the plant supports the overall health of meadow and waterside ecosystems where it naturally occurs.
