Sunflower - Alchemy
This hardy annual displays masses of bright, vibrant blooms on bushy, branching plants with fabulous, contrasting silvery foliage. It is superb for borders and reaches the height of 150cm.
Sow outdoors, from March to May, where they are to flower, 1.5cm deep, directly into finely-prepared, well-drained soil, which has already been watered. Sow two seeds together every 45cm. Seedlings usually appear in 14-21 days. Remove the weaker plant, which can be transplanted if desired. Water well until young plants are established. Or sow indoors, from March to May, 1.5cm deep, individually in small pots of compost. Water well and place in a cold frame or greenhouse. Keep the compost moist. Gradually accustom plants to outside conditions avoiding frosts, before planting out, from May to June, 45cm apart. Flowers from June to September.
