Up to 2.4 metres. Tall slender clumps have pretty, delicately dissected grey green foliage and darker stained stems are topped by diaphanous clouds of small lavender mauve flowers with prominent yellow stamens.
Very lovely edition to the back of any border in sun or light shade on a reasonable soil that neither gets too wet in winter or too dry in summer
