PLANT ID PLEASE

Can you dig around the base and see whether there is a bulb or what root type it has?

did you have any fritillaries {imperial type} Its sort of similar. A lot of foliage to be an allium? as that was my second thought.

My OH says some of the cammasia did something similar last year, not that i remember!

I vaguely remember planting a bulb in that place but can't for the life of me remember what it is! (yet another 'senior' moment!) lol
I did plant a bag of fritillaries but they are in a tub, whereas this is in the main garden and there is only the one (as opposed to a bag full)

did you plant a foxtail lily? though its not quite right for that either. [well not like the ones in mine]

I definitely did not plant any lillies Seaburngirl. Well looks like I'll just have to wait and see! lol

Looks rather similar to my Frittilaria persica...........

yes it is similar to mine too, i had forotten i have 2 in pots :o)

I think Meanie and Seaburngirl are on the right track here.
It's looking very healthy whatever it is.

Looks like Frittilaria persica. I have Hyacinths growing in several parts of my garden that I do not remember putting there and they are much larger bulbs than Frittilaria, so it is possible that you put one there when moving plants/compost?

Thanks everyone - I'll keep you all posted as it grows!
