Can anyone help identity this plant?

When were the pictures taken, Dingo?

Sternbergias are looking like that right now and have a reputation for not flowering unless things are just right. I had one flower last year and none this.

Yellow, flower in autumn, with no leaves look a bit like a crocus, leaves appear over winter, die back in summer. LIke a warmer drier climate than ours.

Sternbergia lutea if you want to google it

Lovely when they flower.I've had them for about 20 years. The leaves have increase and I've had the WOW! moment twice in that time.

But they might not be sternbergias so don't chuck them out yet

Nothing to lose. In well drained compost in a sunny spot you might at least find out what they are

Hi, I think this might be an Iris foetidissima, this has evergreen leaves similar to your picture, tiny insignificant iris flowers, followed by large orange/red berries.  Ours has been in the garden for several years and only flowered for the first time this year.

Hope this helps.

soon tell, break a leaf, the iris stinks. Or dig one up. Sternbergia is a bulb, Iris foetidissima just a root.

I think we have a bulb here. 

It looks incredibly like my Bluebells, they are about that size with the spine/crease down the leaf

Looks like a sedge to me and they do spread.

Or Iris unguilaris which takes years to re-establish after being moved but once it starts flowering hardly ever stops.

I'll stick with Sternbergia lutea. based on appearance and it not flowering in the 3 years Luckydingo has lived there. Sternbergia are just so good at not flowering.

You may have to just wait and see as some dont flower for the first few years while the bulb grows. I plant more of these from seed every year and they can take a few years to get to floweing stage. 

They also look a lot like Agapanthus or even Hemerocallis that are not doing too well!

The mystery continues

Im fairly sure its a bulb. Definitly not evergreen anyway. Always starts to make an appearance after my hostas, lupins, etc have reached the backend of their season.

Il try that trick with breaking open the leaf though.

Looks like a Crinum to me. It is a summer flowering bulb, can be evergreen (mine is) Could be that it hasn't reached flowering size. Last owner may have removed clump to take with them to new home and small bits left behind are coming up...

Luckydingo. You've got to get one of these flowering, the suspense is too much.

I'd dig up and pot up now. Keep them with their soil and they won't notice. You'll know if it's a bulb if nothing else. If you've got several try one in hot dry, another in dry shade etc. see what happens
