IPM1007, Revised November 2009
Winter annual broadleaf
A winter annual weed that develops as a basal rosette, then produces flowering stems that have a “bottle-brush” appearance. Seedlings have cotyledons that are hairless, oval and occur on long petioles. Rosette leaves are without hairs, oval in outline, and lobed along both sides of the leaf. Rosette leaves do not usually persist once flowering stems are produced. Leaves that occur along the flowering stem are lanceolate or linear in outline and do not have petioles. Flowers are produced at the ends of stems in a dense “bottle-brush” inflorescence. Individual flowers consist of four white or greenish white petals and are small and relatively inconspicuous.
