Dazzling dahlias

Reviewed 21st August 2017 by Linda Jackson

I've grown dahlias from tubers with mixed success so tried seeds this year without great expectations but they are the best dahlias I've grown. Easy and reliable to germinate, sturdy plants some of which are well over a metre high and with masses of flowers from mid June. The colours are lovely by and large although I'm not a fan of acid yellow, with some better than named varieties and what's wrong with a bit of serendipity in the garden? Brilliant plants and all for £1.95.
