Most biennials tend to be hardy as they need to make it through their first winter before flowering, but not all annuals are. Half-hardy annuals can’t take any frost and need to be started off and grown on under glass and planted out only when there is little chance of frost – otherwise they’ll turn to mush. Hardy annuals can handle frosts and even take a slight freeze. They can be sown direct in spring, or in autumn for earlier flowering and bigger plants the following spring.
