This tall species is like an improved Thalictrum flavum, with strong upright stems, but has better blue-grey foliage and fluffy heads of pale lemon-yellow which are fuller and more massed right through July and August. It is ideal for sun or partial shade in any fertile soil.
Sow immediately at any time onto preferably a soil-based compost, covering with fine grit to approximately their own depth. Germination MAY be quicker if kept at 15 to 20 degrees C. but many seeds WILL NOT come up the year they are sown, needing winter chilling after sowing, and ONLY come up with natural spring germination.
