does anyone know what plant this is

Dracunculus vulgaris aka the Dragon Arum.. I've wanted one for a while now!

Martin, I did not know that Dranunculus would survive outside in the UK. Is it not supposed to require a hot, dry summer rest? Where about does mum live?
Rydeboyz, I think you will find this in the Jaques Amand catalogue.

Yep certainly Dracunculus Vulgaris, I have 5 shoots coming up at the moment. It is also known as the Voodoo lily. One word of caution, when the flowers are open they let off a really awful smell like rotting flesh as they need to attract flies to pollunate them. This only lasts for a few days but it is best not to plant it too close to your house or a neighbours house. It is more than possible to grow them in the UK, you can grow them in pots if you are concerned about the temperature.

I grew this outside for many years, even in heavy clay!

I bought one a couple of weeks ago and it is in a pot. Once flowered it will go down by the pond.

Thanks for that link Bulbaholic. I found some at J.Parkers and got some Tricyrtis aswell while I was there (and free Pulsatilla).

I'll definitely be buying from there this Autumn though as they have Nomocharis which I've been looking for for ages!
