About

Seseli is a genus of herbaceous perennials within the Apiaceae family, known for their rigid grey-green leaves and compact clusters of white umbels on erect stems. These plants form clumps with a tufted, columnar upright habit and develop a woody base with a conical tap root. Suited to full sun and sheltered positions, they thrive in fertile, well-drained alkaline or neutral soils such as chalk, loam, or sand. Hardy to UK zone H7, Seseli is ideal for cottage and informal gardens, gravel gardens, flower borders, and as cut flowers, with interest in spring and summer.
