I have grown dahlias from seeds this year from the cactus mix as well as, experimentally, from Magenta Star, a Sarah Raven plant that I’ve had for two or three years. The cactus mix seeds were a delightful variety of, mostly single, brightly coloured flowers. Each is a type that I would hope to overwinter...plenty of mulch, I hope, should see them through. As an aside, the plants from Magenta star vary from light pink to red but none has the dark leaves of the parent plant. I’ll take cuttings in Spring.

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.
