Can you ID? Spikey plant with tall central flower stem.

Hi everyone, can anbody identify this plant for me? When I first planted it it was quite small, but now it seems to have grown somewhat, a few months ago a large central spike appeared, this has now died away, but its started again and looking at it, it looks to me as if its now two plants, and I was wondering if I could split it, and if so how and when? The leaves(?) have extremely sharp small spines on them if that helps. Sorry for the picture quality.

Any advice would be greatly appreciated.

Cheers

Is that a Yucca?

 

Hi everyone, thanks for your replies.

I does look a little like the Yucca, BUT there are never any white flowers like in the picture. Could this be because of the weather conditions, its in a north facing garden.

Another suggestion is Giant Sea Holly, but again as far as I can see this has 'proper' flowerheads, whereas on my plant the flowers seem to be green hued and very small.

Is it one of the big Eryngiums, like E pandanifolium.

 

It could be Palustris.There is a bunch of different kinds.

 

Have a look at E. eburneum. E pandanifolium has smaller reddish flowers and E. agavifolium has blackish flowers.

 

Identify this spiky plant

Hi everyone, thanks for all of your replies. I would take a guess that e.pandanifolium is the current favourite?

I'm posting a picture of the flowerhead if that helps with final identification. The flowerhead does not change in colour, nor does it develop any further than in this picture, the flowers and stem die off and turn brown. The actual flower heads are only about 1cm from tip to base and about 5 mm across so they are small. The garden is north facing and the plant is in the shade of a pear tree.

It looks as though another 'spike' is beginning to develop which would be the third this year. The plant seems to like it where it is, its growing rapidly.

I really like the plant it is very striking and I was wondering how to divide it as I'd like to see it elsewhere in the garden.

Cheers Kantblue

Not E. pandanifolium then. The flower heads on that are more widely spaced out and are definitely red. Still go for some form of Eryngium though.
