Horse nettle

Description:

It is a perennial 10 cm[4] to 1 m in height. The stems are covered with nettle-like prickles, ranging from very few on some plants to very dense on others. Leaves and stems are covered with downy hairs (trichomes) that lie against and hide the surface, giving a silvery or grayish appearance. The leaves are up to 15 cm long and 0.5 to 2.5 cm wide, with shallowly waved edges, which distinguish it from the closely related Carolina Horsenettle (S. carolinense), which has wider, more deeply indented leaves. The flowers, appearing from April to August, have five petals united to form a star, ranging from blue to pale lavender or occasionally white; five yellow stamens and a pistil form a projecting center. The plant produces glossy yellow, orange, or red berries that last all winter and may turn brown as they dry. — Wikipedia

Solanum elaeagnifolium, the silverleaf nightshade or silver-leaved nightshade, is a common weed of western North America and also found in South America. Other common names include prairie berry, silverleaf nettle, white horsenettle or silver nightshade. In South Africa it is known as silver-leaf bitter-apple or satansbos ("Satan's bush" in Afrikaans). More ambiguous names include "bull-nettle", "horsenettle" and the Spanish "trompillo". The plant is also endemic to the Middle East. —Wikipedia
