Overview

M. incana - commonly known as Stocks - has many cultivars and is a perennial with narrow, grey-green foliage and a woody base. Flowers are borne on spikes of sweet-scented pink, mauve, purple, violet or white flowers which some say smell like cloves. Stocks are widely grown as annual or biennial bedding plants in gardens, and commercially as cut flowers. They make good additions to a sunny border and add colour from Spring to Summer in milder climates.
