Winter approaches, lace cap hydrangea blooms on

As winter approaches, the lace cap hydrangea refuses to stop blooming. Even as the leaves turn to autumn colours, the lacy flowers remain in place, slowly fading.

I waited many years for this shrub to bloom. Now that it's begun, it refuses to quit.

The flowers have been there since late July. To make future blooms blue, advises garden expert Steve Whysall, this is the time to apply a dressing of aluminum sulfate.
