Canna Lilies

Roughly how tall do Canna Lilies grow if planted in an outside flower bed?  Do they prefer dry or moist soil - with or without a good compost mulch or grit and sandy soil.

    depends upon variety: between about 2 feet and 8 feet +
    Devon.

    Too tall for where I was going to move them to then, thanks @Hostafan1 .  I have just moved some Crocosmia Lucifer from under our window because they were too tall, but I can see from  your comment that Canna's will be just as tall or even taller.  I will have to put my thinking cap on to find another place for them.

    They like plenty of water, as they lose a lot of water from those big leaves.

    Thanks @Alan Clark2 in Liverpool I will water them regularly when they begin to grow next season.  At the moment they are planted under pine trees and are struggling.  They have never flowered and I know that if I don't do something with them they will eventually give up the struggle to survive.  I will take a look around the garden when the rain stops, and try to find a more suitable place for them.

    I grow a couple in pots and that variety only grow to 2 foot or so. But whatever variety MD grows they are about 6+ft. So check your variety......

    @Guernsey Donkey2. They’ll do far better in the open ground where you live, my daughters in Cornwall survive the winter, she’s been trying to get rid of them, they still keep coming up.

    I would be concerned the pots would topple over in the wind if I planted tall cannas in them. I am tempted to plant them against a wall but in full sun, that way they won't be flattened by the wind.  I assume I should move them in the autumn or winter?

    My daughter leaves hers in the ground, there’s loads of them now and I don’t think she could dig them out.

    Don't know if it helps...but here's a snap of my Canna from the Cannova series that are smaller and they don't need huge amounts of sun in order to flower. First time I've grown them and they haven't stopped flowering in two months.
