Be mindful that David Austin's English roses were bred in a British climate where it is generally cool and wet. However this year the latter part of spring continuing into summer has been very warm with hardly any rain. At present parts of the country have been issued with amber health warnings from the Met. office because of temperatures over 30C. I grow 'Munstead Wood' and it hasn't performed well this year, despite watering the second flush has been poor with the flowers hardly lasting two days. 'Septer'd Isle' is struggling and not performing well in these conditions too. Only 'Summer Song' is growing well recently throwing up two very healthy shoots. But like the previous roses the flowers are over after two days. In a normal year these roses struggle in the damp and cold in my garden.

MW lasted longer in the vase than it did on the shrub for me.
