Arisaema amurense

Wow that's gorgeous.

I'm not overly impressed with Arisaema plants. They do not do well in my garden and disappear after one season. This looks very healthy and I do like the colour but carnivorous plants make me squirm.

These are not carnivores SG

I thought they ate flies etc that crawled inside. I dk why they fail to grow here because I planted them in areas where the drainage is good.

I would have thought it would be ideal there.
A woodland soil that holds moisture,but is well drained.Leaf mould or composted bark would be beneficial.
Plant deeply,bigger ones up to 6 inches.
Dappled shade and definitely out of bright sunlight

You have described my garden but ?
