What it's good for, and what it isn't

A tall, airy perennial: above columbine-like, finely divided foliage it lifts a cloud of tiny lilac flowers on thin purplish stems about 1.5 m high from midsummer. Besides the species, this group includes the double 'Hewitt's Double', white 'Album', 'Ankum', the even taller hybrids 'Splendide', 'Splendide White' and 'Elin' that can reach 2 m, and the similar, sturdier-stemmed Thalictrum rochebruneanum. Plant it at the back of a border in moist, humus-rich soil, part shade and shelter from wind, and expect to stake it.

Watch out for

The thin, tall stems flop or tangle in wind and rain, so they need staking or the support of neighbouring plants. It copes badly with hot, dry summers: in Central Europe it needs part shade, mulch and watering in drought, and in dry spots it gets powdery mildew and scorched foliage. It emerges late in spring, and a newly planted or divided clump takes a year or two to build up. Rust occurs occasionally.
