Folk medicine

It is used for its healing properties against haemorrhoids, although in herbal medicine it is actually the common toadflax (Linaria vulgaris) that is more commonly used. The latter is larger, grows at lower altitudes and has yellow and orange flowers.

Ideal habitat

It grows on scree, in gravelly slopes, but also on the banks of streams, usually on calcareous soil.

Where to find it

It is a common species in the Alps and, more generally, in the mountainous regions of central and southern Europe. In the Aosta Valley, it is found almost everywhere (except in the south-eastern valleys) at altitudes generally ranging from 1,700 to 3,300 metres, but also much lower down along the Dora Baltea. For example, it has been found at an altitude of just 345 m in the municipality of [[Arnad]].

How to recognise it

It grows to a height of 2–10 cm, with ‘snapdragon’-like flowers arranged in clusters. The corollas are a deep violet colour and usually feature two orange patches.
