Lucifer is bomb-proof and the tallest.

Hellfire should flower easily but perhaps the corms have become congested? That seems to be a common reason for not flowering in several crocosmia cultivars. You could try digging them out and replanting further apart with some slow-release fertiliser.

+1 for Lucifer. Love it

PM me and I'll send you some Lucifer.

Definitely Lucifer,and I agree,with all Crocosmias,they benefit from splitting..A lovely plant,and well worth having..

thanks all for replys will wait till they die back then lift and separate. Bri

Hi, I agree C 'Lucifer'is the tallest pure red, but there's C masoniorum, which is about a foot taller, but is only an orangey red, but is also hardier than C 'Lucifer, being borderline completely hardy, Derek.

Can't send him any of those though...
Derek, I never know Lucifer was not totally hardy - its been fine here but we do normally get pretty mild winters.

Hi Sue, yes it's classed as frost hardy, can stand about temps down to about 25f, but as you say you usually get mild winters they should be ok.
T he 'lucifer you sent me last year, I started off in a cold greenhouse, and planted them in a sheltered spot in spring, they have done well, and have been flowering for 2 or 3 weeks now, thanks again, hope we don't get a very cold winter, our winters aren't usually too bad, but we do usually get to about 18f, so fingers crossed we have another mild 1, Derek.
