Greater stitchwort, Stellaria holostea
Greater Stitchwort is a very common plant of wayside verges, hedgerows and open woodlands.
Until it flowers, however, it is easily missed, as the foliage looks similar to grass.
Greater Stitchwort is a relative of Common Chickweed, Stellaria media, and like Chickweed, Greater Stitchwort is an easily-collected source of edible wild greens.
The green shoots can be chopped into salads, steamed or quickly boiled.
You can eat the flower buds and flowers and these can make an attractive addition to a wild salad.
