Dahlia 'Roxy' just keeps flowering!

Reviewed 28th January 2017 by Bonar

Last year I bought 3 rooted cuttings of Dahlia 'Roxy' and grew them on before planting them outside in late May. From mid July onwards they just kept flowering until the first frosts. They have intense magenta flowers and the bees seemed to love them too. I grew them in big glazed pots where they seem to flourish and I fed them well. So now I'm looking forward to starting them off again this March... (along with all the others I've started to collect) ;) Recommended!
