Thompson & Morgan - Flowers - Petunia Rainbow Mixed F2 Hybrid - 750 Seed
Petunia - Rainbow Mixed F2 Hybrid
F2 means seed saved from F1 hybrids, more economical but not quite so splendid as an F1. Nonetheless you are sure to like this mixture of fine vigorous plants which contains twelve of the best colours including of course the tricolours. It flowers summer to first frost. Height: 30cm.
Sow late winter to mid spring at 21-27C in a good seed compost. Sow seed on surface of compost and gently firm down compost. Keep soil damp but not wet. Do not exclude light, sealing in a polythene bag after sowing is helpful. Germination usually takes 10-21 days. When seedlings are large enough to handle, transplant and grow on in cooler conditions. Gradually acclimatise to outdoor conditions for 1-15 days before planting out after all risk of frost, 3cm apart in a sunny spot on light well drained soil.
