Hedychium question

Outside my front window. I have group of Hedychiums - gardnerianum, coronarium and coronarium 'Gold Spot'.


Gardinarium flowers very reliably, 'Gold Spot' managed to open a couple of flowers, before aborting at the very start of winter. That was the first time it has flowered.
At the same time. Coronarium was also budding up for the first time and a fair few of the then also aborted.
Some, however, are still growing, albeit very slowly.


Is it possible that they will hang in and open once the weather starts to warm up?

 

Possible I suppose, but gingers always get cut back by frost here, which is why I dont bother trying to grow any that flower late in the year.

I'd leave them and see what happens.

 

Definitely worth leaving - if they're still growing, then it's all feeding the rhizome, so even if the flowers are rotten, it's good. Like @pete , mine got damaged by frost, so I left them fallen to mulch the rhizome (with added hay).
But I have trouble getting even gardnerium to flower outside. You're obviously in a more favoured area.

 

Gardnerianum, Tara, and densiflora are the only ones that flower for me early enough, having said that I've ordered a new variety, to me, this year, griffithianum.

 

When I lived in Oz, I grew gardinarium (?) in full sun, but with a cool root run. They did get sun scortched in summer, but flowered profusely.
My current garden changes continually, as I chuck plants that don't 'fit', and I'm quite ruthless about it. I do apologise to the plant before I bin it, though.
I've got another bed with gardenarium, densiflorum "Assam Orange", both of which flower well, and another that I "think" is coronarium, but it hasn't flowered yet.
At this point. all my Hedychium are still in the green, apart from the densiflorum whose canes all died back a couple of months ago.

 

The hybrid ones Devon Cream and one I was sold as Luna Moth (but isn't, it's like a bigger Devon cream) both flowered well last year.
I'm amazed yours are all still green. Even the ones in my cold greenhouse aren't. I'm a sucker for hedychium, roscoea etc...
