Two plants with bright yellow flowers, catch the eye in these parts at the moment. One is native to the UK and the other is an invasive species. First, the native one. Common Toadflax (Linaria vulgaris) is a common sight around these parts at this time of year, but its familiarity does not detract from its beauty.
The second of my yellow flowers is the non-native Canadian Goldenrod (Solidago canadensis). Growing to about 5ft tall and topped with a long inflorescence of frothy, yellow flowers.
