| Identification | Field Pepperweed grows up to 1.5 feet tall, the stem densely hairy. The leaves stand erect or strongly ascending, sessile, lance-shaped and a bit wider at the base of the leaf, the margins not toothed. The flowers are small and white; the fruits ovate to rather rotund, widely winged. L. perfoliatum differs in its yellow petals, deeply clasping stem leaves, and pinnatifid basal leaves (vs. toothed). The native L. virginicum has similar white flowers but has narrower leaves, with petioles. | |
