Below is a selected list of Narcissus species, varieties and cultivars which currently (2020)[1] hold the Royal Horticultural Society's Award of Garden Merit (AGM). Narcissus (daffodils) are bulbous perennials which are usually planted as dormant bulbs in autumn (fall) to flower the following spring. Once established they flower reliably every year, with variously trumpet-shaped flowers in a range of colours, mostly shades of white and yellow. The central trumpet (corona) and the outer 'petals' (perianth segments) often have contrasting colours. Breeders have produced a huge range of sizes and shapes in these flowers, which are among the most popular of all plants in cultivation.
