Very often, following heavy rain Petunias look completely washed out. Not any more! The 'Storm' Petunias have been specifically bred to 'spring back' to life after the worst of storms. Add to this their ability to stay compact with many basal branches, you are safe to predict an effusion of summer colour. Mixture contains salmon, white, pink and lavender. Ideal for bedding, containers and borders. Flowers summer. Height 30-35cm (12-14in).

Sow from February to April at 21-27C (70-80F) on the surface of a good seed compost and gently firm down. Keep soil moist 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 into 7.5cm (3in) pots and grow on in cooler conditions and shade from strong sun. Gradually acclimatise to outdoor conditions for 10-15 days before planting out in May-June, after all risk of frost, 30cm (12in) apart in a sunny spot on light well drained soil.
In dry weather, water until well established. For window boxes, baskets and containers plant up in May and grow on in good light, to allow them to become well established before hardening off and moving outside.
