Bulbs are a valuable asset in the garden, many of them flowering in spring when little else is in bloom. But, as well as the common daffodils, snowdrops, crocus and tulips we all love to grow, there’s a host of interesting and unusual bulbs we can add to the mix.
As well as spring-flowering bulbs, choose summer- and autumn-flowering bulbs to increase your season of colour. Unlike herbaceous plants, bulbs are almost guaranteed to flower, so you can count on them to provide colour and interest in a set display.

Snake’s head fritillary is a native British flower and is therefore extremely hardy and easy to grow, and is ideal for growing in a variety of situations including pots, spring borders and in long grass.
