Fluellens are rather sprawling, often overlooked plants with rather attractive snapdragon like flowers, the upper half brownish violet and the lower half yellow. Unlike snapdragons and toadflaxes the flowers are borne in the leaf axial along the stem rather than in a terminal raceme. Surprisingly the main difference between the two species is that the round-leaved fluellen has round leaves whilst the sharp-leaved fluellen has sharp, arrow shaped leaves.
In flower from July to October.
Sharp-leaved fluellen is an annual that came in to Britain with the introduction of agriculture. It can be found on heavy or light, lime rich soils at the margins of arable fields, on waste ground, track ways, gardens and other areas of disturbed ground.
Can be sown from seed sown at any time of the year.
