Trinity in scarlet

Actually the colour of these roses is a little more pink than scarlet, but it's pretty intense. These are the second rank of roses from Josephine Bruce, the elderly lady in my garden who produced such a tall and vigorous shoot this year. The first -flowering bloom which I blipped a couple of weeks ago didn't last nearly as long as it should have; it quickly became waterlogged in the torrential rain and one morning we found all its petals scattered over the garden.

This trio of beauties finally flowered a few days ago, and yesterday the promise of heavy rain and high winds (and they came, just as promised) persuaded me that they'd do better indoors, where we can see and smell and enjoy them. They're all on the one stem, which fits beautifully into an antique glass bottle meant to hold oil or vinegar at the table. 

Meanwhile, in the once-more-rainy garden, another group of buds is taking shape on a subsidiary branch. Tell me, gardeners out there, when it's finished flowering for the year, should I prune this new stem hard back, or leave some of it for next time?
