What is this plant?

[WildThongsHeartString]

Tall green grasses with deep orangey red spires. Big clumps and it seems to spread every year. Some are very much in flower just now but others are a bit further behind.
TIA

Difficult without a photo, but try googling crocosmia (aka montbretia)

Well done both! That's it. It's in a few different parts of my garden (was here when I moved in). It is lovely, eye catching, but I was wondering why there is a couple of clumps with no flowers or buds at all, just plenty of the grassy bit?
