What is the best way to store cannas during the winter. I have two lovely big plants that have just gone black due to the frosts. I would like to try to keep them for use next year.

According to the RHS:
'Cannas are lifted after the foliage has been blackened by frost. Remove dead leaves and loose soil and store in trays of sand, coir or vermiculite, with the crown just showing. Keep just moist in a cold, frost-free greenhouse or conservatory. Container-grown plants can be stored in their pots.
Plants can be risked outdoors in well-drained soils in the mildest regions by protecting the crown with a thick layer of dry winter mulch such as bark.'
Hope this helps. :)

I have left mine outside for the past two seasons and they have flourished. Having said that, my garden is in London which is relatively mild and they are growing through a weed suppressant membrane and a layer of gravel. I wouldn't risk it if I lived in the countryside or further north.
