As I qualified as a florist a few years ago, my family are always buying me flowers, to play with. The only ones I don't like indoors ( though not a flower) are those cabbage stems that they put in mixed bunches sometimes. The stems in water start to stink so quickly, and they are too fat to use with florists foam. There are much nicer foliages to choose from. Yes I love my flowers in the garden as well, but I try to grow some things just for cutting, and doing a pretty arrangement.
Not keen on dahlias indoors, as I always remember earwigs crawling all over the table as a child!
