Canna lily
in Plants
Guidance and advice please. How shall I keep these canna lilies over winter? Can I leave them in unheated greenhouse in the pots? I am in near Heathrow Airport.

You've got some time yet though, don't cut them now. They are still growing flowering stems in your photo, so keep deadheading by snapping off the seed pods when each individual flower is finished (gently tug the flower, if it's done it'll slide off leaving the seed pod behind).
