Masses of large flowers, in a smashing range of colours, will brighten up your patio containers and flower beds throughout the summer. HHA - Half hardy annual. Height 23-30cm (9-12"). (VALUE HYBRIDS - Hybrid flower seed, as most people know, gives the best results, but because production costs are high, the seed can be quite expensive. In recent years, Suttons have been working hard with flower breeders to find ways of reducing these costs and the result is our extremely popular Value hybrids range of high quality seed at great value prices.) NB: PETUNIA FLOWER COLOUR VARIATION - Environmental factors at the beginning of a season sometimes affect the colours of certain varieties, particularly those with striped flowers.
