Filipendula vulgaris aka Dropwort

Filipendula vulgaris, or dropwort, belongs to the rose family. This perennial grows in clumps and loses its leaves each year. Its native range spans the Azores, northwest Africa, Europe, and temperate Asia. It reaches southern Siberia and Iran. It is native to Britain and Ireland. Wild plants grow in dry grassland, often over chalk or limestone.

Garden plants stand about 2–3 feet (0.6–0.9 metres) tall. The RHS gives an upper height of 3.3 feet (1 metre). Clumps spread about 1.5–1.6 feet (0.46–0.5 metres) wide. Most leaves form a low rosette near the ground. This leafy mound reaches about 1 foot (0.3 metres) high. The dark green, pinnate leaves have many small, toothed leaflets. Their fine divisions give them a fern-like look. Spreading rootstocks bear tubers beneath the soil.

Slender, branching stems rise well above the leaves. They carry loose clusters of small, cream-white flowers. The buds may show pink or red before opening. The blooms have a scent and make a clear contrast with the leaves. June and July form the main flowering period in Missouri. Chicago records flowers across a wider May-to-August span. The RHS places flowering in early summer and midsummer.

Grow dropwort in full sun with soil that drains well. Some afternoon shade helps in hot summer climates. It prefers fertile soil rich in humus and steady moisture. Yet it also copes with dry soil and drought. Neutral or slightly alkaline soil suits it best. The RHS lists clay and loam as suitable soils. Missouri Botanical Garden lists USDA zones 3–9; the RHS rates it H6. Plants need little upkeep and can seed freely. Divide clumps in spring, or grow new plants from seed. Cut back tired leaves after bloom. Good moisture helps the foliage stay fresh through summer.

Use dropwort in borders, cottage gardens, meadows, or natural plantings. Its low leaves can also form ground cover. Deer tend to leave it alone. Serious pest trouble is uncommon, but powdery mildew and fungal leaf spot can occur. Plants For A Future lists young leaves and roots as edible, raw or cooked. The roots taste bitter and have served as food during shortages. That source reports no known hazards; this does not establish safety for pets.
