Garden mums bring masses of affordable, long-lasting colour and flower until December along with their shapely, pleasingly mildly acrid-smelling chrysanthemum foliage. Garden mums branch naturally, being bushy dwarf versions of the florist’s chrysanthemum, and therefore are not quite hardy. Arguably they are now, unlike garden mums, under-appreciated and due for a dahlia-style comeback. Florist’s chrysanthemums flower in summer and autumn in a sunny, fertile border or in large pots, with some canes and string. Fertiliser – blood, fish and bone, for example – is usually added two weeks after planting out, while potted plants get a weekly liquid feed.
