Plant identification - help please!

Hello!
Having moved house in December I am still trying to identify the plants that were left behind, and now springing to life! This one has me particularly stumped (well my Mum really! She managed to tell me most of the others!)
When I dug down to try to plant some spring bulbs I found patterened coned-shaped bulbs. They have now grown to nearly a meter in height in about a month. The stems have an unusual pattern, kind of a stretched version of the bulbs. I have no idea what the flowers will be like, & would wait patiently but 1) not sure if I have to move the surrounding plants again, 2) not sure if I should tie it back/stake it & 3) my mother has no patience!
Any help would be very welcome!
Cheers, Nat

Hi, SunshineNat,
It looks a lot like Arisaema thunbergii - or a very similar species (I think there are a few variations/forms) the leaves in particular. Having said that, I have never seen such a thick clump before. It would fit with the 'bulb' you found - they are actually tubers which explains the elongated form. I'm just stumped as to why they are so happy - they like partial shade, are frost tender, and need neutral to acid conditions - does any of that fit where they are???

Hi Kathy,

It could be! Do they have patterned stems? I can't tell from the images posted! They are in about 1ft of gravel, yes to the partial shade... but it was very cold this winter & apart from being near the house they got no protection. It does remind me tho', there was a couple of dying stems left that looked a bit like 'Lords and Ladies' lying in the area! Thanks for the ID!
