Cannas
Would welcome advice as to why my cannas haven't flowered; they were overwintered in frost free greenhouse, planted out once danger from frost had gone & they were shooting; have grown about 12' tall but no sign of flowers?????? Anyone out there have any suggestions please??

Good point--I also put them straight in the soil; ---as I did with my agapanthus & then heard Monty say tonight that they should be kept in pots!!!
So much to learn & remember!!
I grow Cannas and yes they need heat early on so they get a longer growing season,which they need to flower. Also don't forget they need to frost once before you put them somewhere frost free, this takes them into dormency.
There are no definitive rules, I have cannas,ginger lilies and bananas in the ground permanently. These plants are incredibly greedy plants! you cannot over feed them in my experience. I give the cannas and gingers a dry mulch after cutting back in late autumn. then when soil warms and growth is visible, I give them as much well rooted manure as possible.
Hi Bamboogie, re your reply doesn't your method depend on what part of the country you live ? If I lived up north I don't think this would work.
Hi chrissy, yes, I'm in devon, so milder climate than up north, though I've heard of gardens on the west coast of Scotland that leave cannas in the ground over winter. Whatever works for you I guess.
i was trying to suggest feeding the cannas to get them to flower.
Many thanks for all the advice--now to do it, & have flowering cannas next year!!!!
Cherry - feeding well is important. They're hungry plants. I'm not in the balmy south west area of Scotland that Bamboogie mentions - I'm in the wet cold middle part, and we have a short season compared to the south - but it doesn't mean I can't grow them! A sheltered spot and the right care - and it's amazing what can happen.
You'll have great Cannas next year
I live in west central Scotland - not where that photo is...
I'm in Devon too and I was wondering , now I have a nice new polytunnel with no netting which I reckon won't have much frost , if any, could I keep them growing over the winter months, or , is it best to have them " frosted" and leave them dormant?
I have two wonderful specimens grown from tubers given to me by the owner of a holiday apartment in which we've stayed in Corfu. This year they grew to about 2m high and have had the most wonderful display of coral pink flowers all summer long.
