Hi,
I've had these in and around my garden for years, in fact i thin out more than I grow but I can't recall if they flowered first year or not but rest assured they will clump-form if the location is right. I find a little light shade,avoiding the heat of the day is benificial . There is also a yellow form which to me is spectacular but alas was lost during the first longish winter we suffered here.
Regards
Chris
And yes Monbretia is correct

This question cheers me up, Gerardine, as I have exactly the same situation here - new corms, lots of foliage, not a single flower. Your advice, Dogsbod, has encouraged me to leave them where they are instead of moving them out into the sunshine. Let's hope we both get stunning displays next year.

I always understood that Monbretia is much smaller than Crocosmia otherwise they seem much the same.

Monbretia is the common name for Crocosmia, usually, but not exclusively, applied to the version that grows wild down in places like Devon/Cornwall - shorter, floppier, orange flowers, highly invasive.

What happens here is as the flowers develop the folage starts to go over and for the first time and only because I joined this great "club" took a photo two weeks ago. Will post on my home page cos am not very good at this blog stuff bit of a pc Dino me :-)

Montbretia is another of those plant names like Geranium for Pelargonium. The chap who was going to call Crocosmia, Montbretia realised before publishing it that the plants had already been given the name Crocosmia. Yet the name came into use, very odd really.

Once they get going in your garden Montbretia is likely to be thug

After 3 years, my Lucifer has flowered quite well this year, the very wet conditions in the spring I'm sure have helped. Crocosmia is the Latin name, Montbretia the common one.

Against all that's been said above about non-flowering, I planted Lucifer corms (kindly sent by a GoYer) in a bright sunshine area and they bloomed first time. I then moved them into a more suitable place for their height and they bloomed amazingly well again - no probs at all.

i have planted them where they will get sunshine (what is that?) all day should i move them to shadier spot?

No - they'll be fine in full sun, Gerardine.
