What a mouthful! A peculiar and almost unheard-of small European brassica with very finely cut tansy-like foliage (tanacetifolia) and a soft woody base (suffruticosa)
I like the foliage best - especially in winter, but the yellow alyssum flowers are sweetly fragrant and popular with insects.
An easy plant for a well drained spot in sun.
