Another of the garden's versatile plants that can be grown under all conditions and different situations. Sow seed in pots or trays in the greenhouse at 18 degree celsius from February to March. Seedlings will be ready for pricking out in about 7 weeks, unless, of course, you are using plug trays in which they can be left to grow on, but do remember to give them some feed when watering. Plant out as soon as chances of frost have gone and they will flower virtually straight away and last right through from June onwards.
