Queen Anne’s lace
Among the most easily grown and long flowering of all annual plants is Queen Anne’s lace (Ammi majus). Growing to well over a metre in height and width, these drought-hardy plants continuously produce masses of flat-topped white flower clusters from spring until late autumn. They require no fertilisers, grow in a wide range of soils and can even be left to self-seed. Packets of seeds are easily available for immediate sowing.
