You might have to wait until it starts putting up some sort of inflorescence before anyone can tell.

Do the edges of the leaves feel sawlike? Could you scratch your fingers on them? Or are they soft and rubbery?

Is it a spider?

If it is a spider plant it's unlike any I've ever seen.

Agree it would be an unusual Spider Plant. Does look a bit like a sedge, Cyperaceae.

Mom had a plant like that. If it's the same it gets beautiful blue flowers.

I couldn't find the name but ill look again.

I think sedge also. As though it was not purchased from a vendor of tropical house plants.

If it had generally similar foliage the one with the blue flowers may have been a bromeliad.

Too bad. It was a beautiful plant.

Not a bromo.

maybe a baby Ponytail Palm.

If it were the same,it would grow a stalk with a cluster of blooms then the stalk will grow baby plants. If in the garden it then falls over too take root,if conditions are right.

Wow,I'm salivating just describing it!

Papyrus?

I think Marcy may be right. Papyrus or a very similar sedge. I'm curious what it will look like when it matures.

Definitely a Sedge, (Cyperaceae). But there are so many that look very similar it would be too difficult to precisely ID without directly examining the plant material. Where did you get it?

Where did the potting soil come from? It would be a bit difficult to mix up a loquat and a sedge seed, LOL.

That's surprising, you put a loquat seed in commercial potting soil you bought and you get a sedge come up. I thought commercial potting soils were sterilised. Obviously that one wasn't. You might have to let it grow up before you can ID it. Most sedges like lots of water. Post some more photos towards the end of the growing season.

That looks like most of the "grass" in our "lawn." I pull hundreds of these plants each week.
