Nasturtium - Tom Thumb
This variety features bright single blooms, and is ideal for borders and where soil is poor. This hardy annual grows up to 30cm in height.
Sow outdoors from April to June, 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 20cm. Seedlings usually appear in 21-28 days. Remove the weaker plant, which can be transplanted elsewhere if desired. Water well until young plants are established. Or sow indoors for earlier flowers, from February to May, 1.5cm deep, individually in small pots of compost. Keep moist. Gradually accustom plants to outside conditions before planting out, from May to June, 30cm apart, into well-drained soil, when frosts are over. Flowers from June to October.
