UK gardens support six main flower types: annuals, biennials, perennials, bulbs, climbers, and flowering shrubs. Annuals cost under 5p per seed and flower within 8-12 weeks. Perennials return for 5-20 years, reducing long-term cost to under 50p per season. Planting at least three types per season guarantees 8 or more months of continuous colour. The RHS lists over 4,000 Award of Garden Merit varieties suited to British conditions across zones H3 to H7.
