It is possible to create a succession of colour that will last for many months using flower bulbs. For late winter and early spring colour, bulbs such as snowdrops and crocus will kick off the season. While daffodil, hyacinth and tulip bulbs will follow hot on their heels, with spring flowering. In early summer bulbs such as alliums, eremurus and freesias start to appear, while dahlia, gladiolus and canna bulbs will see you through into the autumn.
