What is this plant please?

[Blackcats7]

I have this single stemmed grass thing which spreads like mad, grows from a little corn or bulb. Doesn’t flower or grow seed heads.
Any ideas please?
Tried google image search.

Crocosmia I'd guess. I have some in my garden that never flowers.

I had these at side of my house... nightmare they were. I had to pull up the little bulbs and they take years to get rid.

They look like crocosmia. They are lovely when they flower. I have some im trying to get rid of because they are in the shade so never flower. I just keep pulling them up, getting there slowly.

Not croscosmia no, but can see why you might think so.

What could they be then? I’m intrigued? I have them too and assumed they were Crocosmia that hadn’t had enough sun.

Google suggestions were nutsedge, oat plant, miscanthus. It is none of those.

These are mine.

I have tonnes of these I just pull them all up from the bulb. They never flower.

@Santasbigredbobblehat yep looks exactly the same. I keep removing the little bulbs but there are millions popping up. Wish I could name my enemy!

Some type of onion weed? I’ve been trying to get rid of mine for years.

Something in the iris family because of the way the leaf comes from the stem (and not an onion family weed). What are the differences between yours and Crocosmia - it might help identification

Maybe Sissyrinchium?

It is not clump forming, the bulbs are a different shape (once mature look like three bulbs joined together in a straight row) and the leaves are softer and not sword shaped. And no flowers.

Nope.

No smell or flowers.

What about kaffir lily ,schizolstys ?sp - I can’t find a pic of the bulb .

I'd say crocosmia too looking at that bulb

OP says not - it would be useful to know what the differences are because they’re not evident in that photo

I had crocosmia in front garden and this is not the same. The little bulb in the pic is not how they are when mature. They are then like three spheres in a line. Will see if I can find one to take a photo.

The three bulbs is several years of growth, if you dig up an established clump you get all varieties and numbers of corms. It's certainly not a fixed state, of having three spheres when mature.

The picture you've posted shows what looks like the characteristic flattened leaf base area of a member of the iris family. The leaf colour looks like Crocosmia, as does the fact it's not yet in flower.What we need to take this further is some better close ups, one of the root area, one of the leaf base area, one of the leaf showing the veins.

Same .. hundreds of bulbs

It has been there seven years, never flowers and doesn't form clumps so I honestly don't think it is crocosmia.
I will see if I can get any better photos as it grows

I know mine are crocosmia because I put them there but they don't grow the same because they are in the shade.

I have crocosmia that I'm gradually getting rid of (a shade of orange I find unpleasant) the bulbs/corms do line up like a string of beads.

They do once they've been there a couple of years, but if you fish ne out of your compost heap that's only been there a year, it'll usually have only one corm. I wasn't saying they didn't line up in threes, I was saying it wasn't a universal character, for example 3 corms = Crocosmia, 1 corm or 5 corms = not Crocosmia

Actually OP's LH plant appears to have a string of 3 corms, but they don't look fibrous like Crocosmia.
