Annual, which germinates early from March to May and again in the autumn, these overwinter as basal rosettes until the following year. The first leaves have a distinctive lobe at the tips and have been eaten in salads - they exude a milky sap, similar to Dandelions. Later a flower stem can reach 75 cm. At this stage the basal leaves are tough and more bitter.
It is easily uprooted so hoeing or hand pulling is the easiest way to control this weed in the garden before it can set seed, preferably at the seedling or rosette stages. The seed are not very persistent and the germination rate declines greatly in a few years provided the plants are not allowed to produce more.
