What is this?

I don't know what this is - but found it in the garden near the house of my housesit.

It is a very attractive flower but does not last long - and the flower very quickly falls to the ground.

I'm going to have to do a little research on this flower which is in my garden. I've had several of these plants that throw up wonderful strong long leaves that I sometimes use in flower arrangements. I think most folk grow them for the leaves, but they have a lovely flower.

One of my plants (which is in a pot) has never flowered but this one is in a garden and occasionally throws up this beautiful flower.

It is spring and lots of plants are flowering at the moment, and many native flowers are doing extremely well with blooms - perhaps because of the long dry that we have had.

I've not seen these in any florist, so I don't know how they go as a cut flower.
