Dahlias are aplenty too. My only complaint about dahlias is their lack of scent. Though perhaps if they were scented it might be just too much all in one flower.
In a change from the dahlias and roses (and gladioli too) I decided to arrange a vase of agapanthus when my sister visited for afternoon tea on Wednesday. They were completely stunning and I can't begin to think why I have never used them inside before.
