Linaria purpurea is a species of flowering plant in the plantain family known by the common name purple toadflax.[2][3]
Description
It is a perennial herb growing 30 to 70 centimeters tall with linear leaves 2 to 5 centimeters in length. The inflorescence is a raceme of flowers occupying the top of the stem. The flower is between 1 and 2 centimeters long with five lobes arranged into two lips with a spur at the end. The flower is usually light to medium purple in color. The fruit is a capsule.
There is a pale pink cultivar of the species named 'Canon Went'.[4]
Range
It is native to Italy,[5] but it can be found growing wild as an introduced species in parts of western North America, including California,[6] western Washington,[7] and British Columbia,[3] and it is cultivated as an ornamental plant.[8] It occurs naturally in moist, moderately nutrient-rich places. In the UK it is regarded as something of a weed, spreading readily on stony waste ground and walls, although it is tolerated for its attractive, long-lasting flowers which are very attractive to bees.[9]
Toxicity and chemistry
This plant is poisonous to livestock, though ruminants may tend to avoid consuming it. The larvae of some species of Lepidoptera (butterflies) use this plant as a food source.[10] In a recent study conducted in Italy the plant was found to contain a compound exhibiting antifungal activity, which drastically reduced the production of aflatoxin B1 in Aspergillus flavus Link., making it a potential natural and 'green' anti-aflatoxin B1 agent suitable for use in the food industry.[11]
