Flowers beginning with D

I don't ususlly bother with Dahlias but couldn't resist a Vancouver corm whilst shopping at Morries. The main reason I bought it, apart from it's red petals with white tips, was the size of the corm. It was plump and is huge with  many tubers bigger than my fingers. 

I have it in a mushroom tray now with some dampened compost pushed in around it and sat in my bottom warmed propagator . My hope is that it will send up many shoots that I can use for cuttings, hence making my £2 purchase price seem a bargain.
