Plant Class: Half Hardy Annual (HHA).
CAUTION: Harmful if eaten
Sow indoors, March-April. A warm kitchen windowsill is all you need for starting these seeds. Sow, 0.5cm (¼") deep, in trays of compost. Water well and place in a warm position. A temperature of 15-20°C (60-68°F) is ideal. Keep moist. Seedlings usually appear in 14-21 days. Transplant them, 5cm (2") apart, to other trays when large enough to handle. Always hold by a leaf, never by the stem. Grow on in cooler, but not cold conditions. Gradually accustom young plants to outside conditions (avoid frosts), before planting out, May-June, 30cm (12") apart, into well-drained soil, when frosts are over. Plants can be grown up canes and netting, on a trellis, or through other plants. Flowers: June to October.
