Linaria vulgaris
Ecology
This perennial herb is found in open grassy places, on stony and waste ground, hedge banks, road verges, railway embankments and cultivated land, especially on calcareous soils. It reproduces by seed and also spreads by creeping rhizomes. 0-360 m near Alston (Cumberland).
Status
Trends
The overall range of L. vulgaris is stable, although there have been local losses in the north of its British range and in some areas of Ireland. It was mapped as `all records` in the 1962 Atlas.
World Distribution
Eurasian Boreo-temperate element, but naturalised in N. America so distribution is now Circumpolar Boreo-temperate.
