TOADFLAX, common : Linaria vulgaris
Also known as 'butter and eggs'.
The Wildlife Trusts tells us to Look for common toadflax on waste ground and grassland, and along roadside verges and hedgerows. Our example though comes from the Leven towpath downstream towards the Milburn Park in July.
Although not very high, they seem to stretch upwards in clusters of bright two-tone yellow flowers on their stalks. The flowers have been compared to snapdragons.
Bees and other insects love them.
