Annuals and Biennials Planting Guide & Tips

Plant Type

Annuals and biennials both have limited life spans as plants. Annuals are plants which live for one year and most of them flower in the first three to four months from the time of sowing. Annuals are divided into two groups – summer-flowering and winter/spring flowering. Annual flowers are a favourite amongst gardeners because they give a great burst of colour for little work. Biennials, on the other hand, live for two years. Biennials suit cool climates and are best sewn in spring. We have planting information on a wide range of popular annuals and biennials such as Dill, Oats, Kale, Petunia and Coriander as well and gardening advice on many more annuals and biennials.
