Lolium temulentum, typically known as darnel or cockle, is an annual plant that forms part of the Poaceae family and part of the Lolium genus. The plant stem can grow up to 1 meter tall, with inflorescence in the ears and purple grain. It grows plentifully in Syria and Israel.

It usually grows in the same production zones as wheat and is considered a weed. The similarity between these two plants is so extensive that in some regions cockle is referred to as "false wheat." It bears a close resemblance to wheat until the ear appears. The ears on the real wheat are so heavy that it makes the entire plant droop downward, but the "false wheat", whose ears are light, stands up straight.
It parasites wheat fields. The French word for darnel is "ivraie" (from Latin "ebriacus"), which expresses that weed's characteristic of making one feel poisoned with drunkenness.

It is also gives its name to another edible grain, aquatic cockle, known as "false rice."

The plant is mentioned in the Parable of the Tares in the Gospel of Matthew:
