I don't even seem to notice till they have already bloomed. It is too late then, right?
It's not too late. I don't think producing flowers slows down the growth of the plant much, but making seeds might. So enjoy the flowers and then cut off the scapes - cleaning your tools between plants.
Some hosta flowers I really like. Some seem to be an afterthought. My 'Praying Hands' bloomed last year, but the scape was so short, the bloom was totally lost in the foliage.
