Description
Rudbeckia – Gloriosa Daisies
This is a richly coloured border plant, which is very reliable, and flowers over a long season. This half hardy perennial reaches the height of 90cm.
Sow indoors for surest results from February-April, 0.5cm deep, in trays of compost. Water well and place in a warm position. A temperature of 15-20°C is ideal. Keep moist. Seedlings usually appear in 14-21 days. Transplant them, 5cm 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, before planting out into well-drained soil, May-June, 30cm apart, when frosts are over. Or, sow outdoors for ease, April-May, where they are to flower, 1.5cm deep, directly into finely-prepared, well-drained soil, which has already been watered. Thin seedlings as required. Water well until plants are established. Flowers from July to October.
