Description

I went to the Dutch dahlia trial fields last autumn, briefed to choose no more black dahlias, but my-oh-my you just can't say no to this one. It has marvellous sculptural buds and huge, spiky sea anemone flowers.

Care Tips

Support with a stout stick, tie in every couple of weeks. In the south you can mulch deeply and overwinter them in the ground, alternatively, lift and overwinter your dahlias frost free undercover.
