That is a cool plant , did you start it from seed?

No I bought it in a 3 inch pot from Edrom nurseries back in 2008. It's been in the same pot and has thrived. (The spotted leaves in the photo belong to a hardy orchid, not the Arisarum.) Yes it's a really fascinating and fun plant and very easy to grow.

Thank you for responding

So the mouse like things are the flower ?
How long do they last ?

I have never seen one before and they are truly interesting.

Yes the flowers are the mouse like things. They're related to other arisaemas like 'jack in the pulpit' and have a similar structure but on a much smaller scale. They really are easy to grow and will form quite large colonies in a woodland type situation. The flowers last for a couple of weeks then are mostly hidden by the emerging foliage.
