Canna variety ID

GuybrushGuybrush Posts: 172


I got given a load of Canna rhizomes by a neighbour as I was developing my tropical garden. They've all grown really well and are now flowering, but I don't know what variety of Canna they are. I have a sheltered garden on the south coast but I need to know their hardiness. My neighbour leaves them out over winter but every garden's different and she's quite a way down the road with a different aspect.

    There are nearly a thousand different Cannas these days, due to hybridization, principally in USA, which makes ID from photos well-nigh impossible. Sorry. 

    They are NOT hardy in the UK and need to be lifted like Dahlias. However, when I lived in England I got better results by potting them up and treating them as houseplants, with year-round warmth and maximum sun during the winter. They will probably not remain in flower for very long like this, but the foliage itself is great, especially the purple-leaved varieties. Watch out for spider mites if you grow them this way, however. Good luck. Ian

    Cannas need lifting in the UK.

    Dahlias are now considered hardy in many parts of the country, although I lift mine.

    How can you lie there and think of England
