If your spring planting plans were flattened by torrential rain, scorched by an early heatwave, or simply forgotten in the chaos of life, June is not too late. In fact, some of the best fast-growing annuals positively relish warm soil and long bright days, racing from seed to flower in a matter of weeks while shrugging off difficult weather with admirable cheerfulness.
The trick with fast-growing annuals to sow in June is choosing varieties that can cope with modern summers: sudden drought, humid storms, baking patios, and the occasional cold snap that arrives purely out of spite. Fortunately, there are plenty of annual flowers that germinate quickly, flower generously, and keep going until frost with very little handholding.
