ID required please - grassy thing

Any ideas? 3 of these have popped in a flower bed. I compared the leaves with some nearby Carex Pendula and they are very different - smooth to touch where the Carex is kind of sticky. The yellow stripe down the middle forms quite a strong rib on the underside.

 

They look quite like baby Cordyline australis.

 

The central mid rib is typical of Phormiums but it’s unlikely for them to pop up without a parent plant nearby so I’m probably wrong .

 

I did wonder about Cordyline as my neighbour has several huge ones which have all been flowering like mad. I've never had them come up before but maybe it was just particularly good conditions this year.

Also, I checked a young one I noticed had come up in their garden, but right on my border, and there was no central rib.

 

Glaucous sedge?

 

This is bizarre.
I had this appear in my garden about 3 years ago.
It had the same mid rib.
I knew I hadn't planted it.
I left it to see what would happen.
It just grew larger. It never flowered/
In the end I thought enough ..it had to go.
Only when I touched it to try and pull it out did I discover what a sharp edge it had...it cut my hand.
It reminded me exactly of seaside Marram grass. It had the same felcro type leaf.
No idea how it arrived...maybe a gift from the birds.

Suggestion B....Maybe Miscanthus?
Wait for link below to go to a pic of a leaf.

Miscanthus sinensis 'Adagio' (Dwarf - Recherche Google

Pics below of Marram grass at the seaside.

 

I suspect that would have the same kind of leaf texture as the Carex Pendula.

 

This is definitely not sharp. Miscanthus does look like a possibility, I wonder where it could have come from though. I guess the grass seeds could travel a good distance from a neighboring garden.

 

Cordylines self seed in my garden, although I'd say these are a couple of years old, depends on how often yo weed the area.

 

Cordyline would be the most logical answer; this is an area I am constantly digging up and weeding though as I'm trying different things in it. Pretty sure they weren't there when I planted my lupins in the spring ...

 

I wonder if they could be cordyline suckers in that case, not something I 've seen here, but root disturbance from the neighbours cordyline could possibly cause it.

 

Another possibility has struck me - what about Camassia?

Guess I'll only tell if I try to pull one up! These are right in the middle of the garden though, and quite a distance from the nearest plant.

 

Something occurred to me - could it be Camassia? I put in loads of bulbs last year, though I don't remember putting any in this particular area. And there isn't any foliage showing in the areas I definitely put them. Would seem early for them to emerge too.

 

I don’t think it’s a Miscanthus, the leaves look too wide. The close proximity of a flowering Cordyline sounds like the most likely source of seeds which have developed into small plants. The midrib may be less obvious in younger seedlings, hence the difference between your plants and your neighbour’s plant.

 

Yes, I think it must be Cordyline. I've just seen a picture of a young plant on the Chiltern Seeds website and it looks pretty similar. Not a plant I'm keen on so I won't be keeping them. Though, maybe I'll try putting them in some pots for the patio.
