Groundsel

An annual weed, sometimes ephemeral, of disturbed soil and newly seeded areas, especially where sterilised soil has not been used. It is easily controlled by regular mowing. It will grow in a wide range of soil conditions, from acidic to alkaline, dry to moist and over a range of soil types; it doesn't, however, like shade. It has small yellow flowers which can appear in any month of the year. Its scientific name is Senecio vulgaris.
