Flowers this year only (annuals)

Flowering plants that live for a year - they grow, flower, set seed and die in the same year. Plant them for instant colour and replace them with new plants when their flowers finish. Some will disperse their seeds and these will grow into seedlings the next year, though there's no guarantee where the seeds will land and the new plants pop up! ; Top tip: Swap leftover seeds with neighbours and friends, to experiment and try something new. And it saves money!
