Hi, planted my 2 plants 6 years ago, north facing! They've grown into 2 big mamas with lots of babies around which I haven't got round to lifting.They produce about 8 stems with flowers each summer. They look beautiful when in flower, but the flowers only last about a week in perfection (mine flower in June which seems earlier than other people's?) I so wish I could make them flower again, hence looking at this thread, wondering if I dead head some more flowers will grow that summer?
