Giant scabious (Cephalaria gigantea) bears rounded, black-brushed green buds that open to domed heads of soft yellow flowers atop branching, 5- to 7-foot-tall stems in early to midsummer. The mostly basal foliage stays about 18 inches tall and 2 to 3 feet across; the upright stems are sparsely leafy. Giant scabious is a beauty in a good-sized border and looks right at home in a cottage-style garden. The long-stemmed blooms are also great for fresh arrangements. Snipping off the finished flowers may help to extend the bloom period, but watch out for bees and other insects: they really work the blooms and can get annoyed if you disturb them while trying to deadhead. If you don’t remove the seedheads, you might find some self-sown seedlings in following years. Full sun. Perennial; Zones 4 to 9.
Harvested in July 2020. At least 15 seeds.
