Rubenza is a very unusual variety; the dark ruby red blooms change to old rose as they mature, giving each plant its own tonal effect. The mid-height plants are very manageable in the border, can be grown in pots and used as cut flowers. This half-hardy annual reaches the height 90cm.
Sow indoors for surest results, from February to April, 0.5cm deep, in trays of compost. Water well and place in a warm position. A temperature of 15-20C is ideal. Keep moist. Seedlings usually appear in 14-21 days. Transplant seedlings, 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, from May to June, 30cm apart, when frosts are over. Or, sow outdoors for ease, from April to May, where they are to flower, 1.5cm deep, into finely-prepared, well-drained soil, which has already been watered. Thin seedlings to 30cm apart. Water well until plants are established. Flowers from June to October.
