Hardy Annuals are usually sown in the spring to flower in the same year. Alternatively, they can be sown in the autumn to flower early the following year. Once flowering has finished the plants die naturally. However, many varieties will reseed themselves in the garden to grow again the next year. Most varieties are frost hardy and will withstand cold weather quite well.

There are many varied forms available. Every year seed producers create new strains with ever widening ranges of flower shapes, sizes, colour and growth habits. Most varieties are very easy to grow from seed. Generally all they need once germinated is frequent watering, some feeding and regular dead-heading to encourage a continuous display all summer long.

The most popular Hardy Annual of all time is the Sweet Pea, Lathyrus odoratus.
