The following is a list of tulip species and cultivars which have gained the Royal Horticultural Society's Award of Garden Merit. They are bulbous perennials, originally from sunny, open habitats in Europe and Asia. Thousands of cultivars are available in a huge range of sizes, shapes and colours (other than pure blue). They are usually sold as bulbs to be planted in autumn and winter for flowering in mid- to late spring. They are frequently treated as bedding plants, accompanied by other seasonal favourites such as wallflowers and forget-me-nots, flowering for one season before being discarded. However, in favoured locations they can be left in the ground to re-appear the following and subsequent years. Like many other bulbous plants they require a hot, dry dormant period in the summer.
