Silverleaf Nightshade w/Bee

Solanum elaeagnifolium
The lavender, star-shaped flowers with yellow centers are beautifully set off by the silvery foliage, and large patches of the plant in full bloom are striking. However, the plant is an aggressive, poisonous weed, spreading steadily from deep rootstocks; in a few states it is classified as a noxious weed. The genus name, from the Latin solamen (quieting), alludes to the narcotic properties of many species. This species is also known as Bullnettle. (Photo: Joanna Jarvis)
