The Story
Plant Bio
Scabiosa caucasica, the pincushion flower, is a clump-forming perennial from the Caucasus, standing eighteen inches to two feet high on wiry stems. Flat lavender-blue flower heads, occasionally white, are held well clear of a low mound of grey-green divided leaves, and the projecting stamens give the pincushion effect. It flowers from May into July.
Drainage decides whether this plant lives, and winter wet kills far more of them than cold does. Plant it on a slope or in gritty soil with a neutral pH, avoid mulching over the crown, and deadhead regularly, which keeps the flowering season going well past the stated window.
