advice appreciated

Hi any gardeners who can help
In May I bought 2 chysanthemum plants for half price at a garden centre yet all they said they were chysanthemum plants
.they were small when i bought them so l put them in a window box but i didnt realise how tall they would grow they are very tall , i cannot move them so i have to keep them in box and plant box and plants in garden , but i can only plant them at side or back of the garden where its shady how well do they do in the shade?also as the plants are budding as we had some frost how will they fare any advice appreciated

 

Hi thanks dear sending a photo I have a plastic 2tier green house I put them in their Janet

 

Hi @Janet mahay - welcome! I have some chrysanths in the garden in bud at the same stage, and I think they should flower before the weather gets too bad. Garden centres sometimes sell them as basically rooted cuttings, so you don't realise they are really big plants! I don't think they'll mind a little bit of shade. If they turn out to be big flowered exhibitors' ones, then @Marley Farley is right, they'd need some protection. But mostly I find them pretty hardy.

 

Thanks I have never grown them but I now have a better idea
