  • Garden care: Mullein moth caterpillars can be a problem so look out for them in early June and pick them off as soon as they appear. Remove faded flower-spikes. Apply a thick 5-7cm (2-3in) mulch around the base of the plant in early spring

    It is worth keeping in mind that these plants are mainly biennial so although they usually self-seed freely the plant will only live for two years
