DEAD-HEAD PERENNIAL FLOWERS

Trimming off spent flowers neatens up daisies, dahlias, osteospermums, wallflowers, penstemons and other perennials that are looking tired. You will often get another flush of flowers. Leave alone those you want to save for seed or those seedheads that look attractive in their old age such as poppies, nigella, sedums, honesty, teasels and grasses.
