The species name honours Père Jean-Marie Delavay, a 19th century French missionary and botanist, after whom a whole raft of flowers seem to have been named. There is an alterative species name in T. Dipterocarpum. Delavay spent much of his time in China, which is - surprise, surprise - where this form of thalictrum comes from, hence its common name of Chinese meadow rue.
Meadows and on the banks of streams at higher altitude are the native habitats of Thalictrum Delavayi, so it's understandable that it prefers a soil that retains some moisture in a garden setting. It will tolerant quite a lot of shade, which makes it a good tall flowering specimen for a shady spot that may otherwise be hard to fill.
Prune back to below the flower heads as they go over, and repeat flowering will be encouraged lower down the stem. In early winter cut back the stems to ground level.
Thalictrum Delavayi Album is a tall hardy perennial with ferny leaves and white flowers with yellow anthers in mid to late summer suitable sun or semi-shade.
