An early maturing Kenyan-type bean which produces heavy crops of slim, dark green 10-12cm (4-5in) stringless pods over a long season. Easy to harvest as the plant has an upright, open habit. Resistant to Halo Blight, Mosaic Virus and Anthracnose, it is the perfect choice for organic gardeners, as Opera has no problems with Botrytis.Sow seeds individually in 7.5cm (3in) pots at 18-20C (64-68F) from mid April for transplanting outdoors after all risk of frost. Alternatively, sow outdoors from late April to late July after all risk of frost has passed. Bean seeds can be sensitive to low soil temperatures, so delay sowing until the soil has warmed up. Sow 15cm (6in) apart, 5cm (2in) deep and in rows 45cm (18in) apart. For early crops under glass, sow in heat from February onwards.Hoe regularly and keep well watered and mulched in dry periods.
