yes just cut them out as close to the plant as you can , I leave them on then take off after they have flowerd , they dont flower for that long I think they look realy nice plus the bees love them as well which is a plus , I had a seeds develope on one I missed off I planted the seed and I have about 10 baby plants 1st time for me

You can cut them off, but they rarely last long anyway, so why bother. They are quite pretty flowers and many of the hosta have scented flowers.

Still, each to their own.. :)
