This is Libertia, which flowers in May, bearing clusters of delicate white flowers on long arching stems:
My Libertia bush is slowly but surely getting bigger.
Although the foliage is nice enough (and remains green even in Winter), the plant needs a bit of maintenance to retain its vigour. I discovered via a process of Trial and Error that you need to remove the old foliage if you want to get a decent amount of flowers. I reckon "a decent amount" for this plant of mine is now approximately 25 - 30 flower stems.
If you hold back the top (green) foliage you will see that down below there are lots of last year's leaves and flower-stems which have dried up and gone brown. These are the ones that need to be removed.
Fortunately removing them is an easy enough task. Grasp each leaf (one at a time, or else it won't work) well down towards its base and tug sharply. It will come out easily.
It's not vital to remove every single brown leaf, but getting rid of most of them is desirable.
As a nod to environmental friendliness, I leave a big handful of the dead leaves in a corner of the garden, where birds can take them to use for nesting material.
By the way, it looks as if we may have a pair of Bluetits nesting in the box I made the other day. Certainly they have been going in and out of it, so let's hope they move in permanently!
