Not normally thought of as a seed raised plant but is fairly easy to grow and well worth the effort. Early sown seeds can produce plants that will crop in the first season, later sowings should be left until the following year before pulling any sticks. Sow the seeds in a seed bed 2cm deep in February to April in rows 30cm apart. Thin seedlings to 15cm apart. Lift6 the strongest plants with as much soil as possible 4-6 weeks later and plant out in the permanent site allowing 90cm all round. First stems should be ready to harvest from late summer, subsequent years will produce crops from May onwards.
