Datura ferox

Like all such species, every part of the plant contains deadly toxins that can kill animals (including humans) that ingest it.

Ferox means "strongly fortified," referring to the fearsome-looking spines on the seed pod.

[3] Datura ferox is a stout, upright annual herb 1.5 to 3 ft (45 to 90 cm) high.

The most conspicuous part of the plant is its very wide, undulate, irregularly toothed leaves, which are covered with soft, downy hairs.

[3] All parts of Datura plants contain dangerous levels of tropane alkaloids and may be fatal if ingested by humans or other animals, including livestock and pets.
