Rudbeckia Daisies are a richly coloured border plant and cut flower. They are very reliable and flower over a long season. Sow indoors for surest results, February-April, 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 into well-drained soil, May-June, 30cm (12") apart, when frosts are over. Or, sow outdoors for ease, April-May, where they are to flower, 1.5cm (½") deep, directly into finely-prepared, well-drained soil, which has already been watered. Thin seedlings as required. Water well until plants are established. Flowers: July to October.
