Monbretia or Crocosmia ??

I'm not sure if the difference or is it one plant with two names
All I know us it's a beautiful sight when there are lots planted in a row....reminds me of my lovely Dad.....we had a 100 ft garden and the full length on the left hand side was " awash" with this lovely plant ..
Watched X factor with Helen and the girls whilst partaking in a Chinese take away...happy bank holiday weekend peeps
I'm working :-(((((
