Plant?

[ew1990]

Does anyone know what this plant is called? It's about ten foot but first time it's flowered xx

.

Looks like a Phormium

Ooh someone near me has one of those in their garden. I'm slightly suspicious it's a trifid.

Phormium tenax

I've got one. It's shot up enormous flowers this year for the first time ever. They are coming to get us.. hide.
