Thalictrum rochebruneanum

An upright, clump-forming herbaceous perennial, forming a graceful, vase-shaped clump. It typically reaches 120-180 cm (4-6 ft) in height and 60-90 cm (2-3 ft) in spread.

Deciduous, finely divided, and fern-like. The attractive blue-green leaves provide a delicate texture throughout the growing season.

Produces abundant, loose sprays of small, nodding, lavender-purple flowers with prominent yellow stamens on wiry, branching stems. It blooms from July to September, offering a long season of interest.

Thrives in partial shade to full sun. It performs best with consistent moisture, especially in sunnier locations.

Excellent (USDA Zones 4-8), indicating it is very cold-hardy.

Prefers moist, well-drained, humus-rich soil. It tolerates various soil types, but good drainage is crucial.

Has a medium water requirement, appreciating consistent moisture. Avoid prolonged dry periods.

Ideal for perennial borders, woodland gardens, or naturalistic plantings, adding vertical interest and a misty effect. It also works well as a "see-through" plant.

Low maintenance. No significant pruning is typically required. Cut back old foliage in late autumn or early spring before new growth emerges.

Best planted in autumn or early spring.
