DESCRIPTION:
Silverleaf nightshade, a deep-rooted perennial, has gray-green seed leaves.
First true leaves have wavy margins and are covered with small star-shaped
hairs. Spreading rhizomes produce young shoots that are dusky, silver gray.
Mature plant is 1 to 3 feet (30 - 90 cm) tall. This well-branched plant has
leaves and stems that are covered with dense short hairs. Showy flowers, 3/4
to 1 inch (19 - 25 mm) wide, have deep violet to light blue (sometimes white)
petals. Fruits are globe-shaped, dull yellow to orange berries. It is widespread
in California's desert valleys, especially in poorly managed fields. Reduced
tillage favors silverleaf nightshade. Once established, it is difficult to
eradicate.
