Description edit

Chaenorhinum minus differs from many toadflaxes in having alternate leaves growing singly. Its leaves and sepals are covered with glandular hairs. Leaves are glaucous and sepals are green or purple. Flowers vary from pale purple to white. It is an annual herb, with a maximum height of 25 cm. It does not spread vegetatively.[3] Flowering occurs June–July.[4]

Habitat and distribution edit

It is such a small plant that it relies upon disturbance to compete with other plants for light. Once a common weed in farmers' fields, it has suffered from agricultural intensification and is now mainly seen in gardens and around railways, as well as roadsides and industrial sites.[5][6] Its UK distribution shows it favours chalky soil.

This species is native to continental Europe, found mainly in south and central Europe, though it reaches as far north as Sweden. It is considered to have 'archaeophyte' status in the United Kingdom ie. is thought to have been introduced many centuries ago.[7] It has also been introduced to the US and Canada.[8]
