A large white flower with a long tube is usually the telltale sign of a flower that blooms at night, since it is often adapted to pollination by long-tongued hawkmoths that only fly in the near-dark. Such is the case of the impressive (to about eight inches long) and beautiful flower of this species of jimsonweed. The fruit it produces is like a spiny apple and gives it several of its other common names. This poisonous plant is found scattered through Trans-Pecos, central, and north Texas, mostly in loose sand and stream bottomlands.
Flowering months: May, June, July, August, September, October, November
