Hello,

I've browsed a great number of plant books, but nowhere I found this species. Does anyone know what this is? The picture is from early August (Dutch climate). Thanks!

Calla lily? Amorphophallus? Will amorphophallus grow there? Some type of aroid.....

It does indeed resemble the seed head of Amorphophallus.

Maybe "Lords and Ladies" Arum italicum before the new leaves grow.

Arum, pest here!!!

I feel sure it is Arum italicum I have them in the garden.

I have them also. The leaves are so beautiful all through winter and into early spring.

That's Arum italicum and it's so incredibly invasive here that I've ceased to find any part of it beautiful.

Interesting...I've never had it pop up anywhere before.....

One of my neighbors had a houseplant of it about 25 or 30 years ago and planted it outside. It has now spread to all of the 40 or 50 homes in my neighborhood. It covers the garden from October to March, obscuring all of the shorter plants. It's apparently impossible to kill too. One of my neighbors got rid of it by mowing it for years, but it came back from all of the surrounding gardens, so he finally sold his house to get away from it.

And it doesn't just spread underground. It ends up in my plant containers and my fish ponds and even grows in the little bit of soil that collects in the crook where branches of trees meet the trunk.

I dispose of the berries before they start falling to the ground, so I haven't had a problem with them becoming invasive. They have been here since the 50's.

It must be your climate that makes it so invasive. That really sounds terrible, but it doesn't do that way here.

I try to pull the top portion off the plants way before they produce berries. I used to try digging them up, but that just releases a dozen little bulbs from the big one and compounds the problem. I think they end up in the containers when birds pick up the berries from other gardens and drop them here.

I have amorphophallus. I don't think (hope) I'l have the same problem with that....we're so much drier down here that I wouldn't think so.

Arisaema fruit are very similar

Wow! I thought I would get replies by e-mail, so I didn't check this forum for a while, thinking there were no replies. Following JRsbugs' links I believe it must be the Arum Italicum. I had no idea it was so invasive. I wonder how the garden will look like next spring. Thank you all!

It depends on where you are on how invasive it is limboy, in the UK it's not invasive and is slow to increase so it's looked on as something interesting and favourable.

We don't normally email anyone here unless it's a private conversation, all threads posted can be useful to others so check in occasionally (or several times a day like many of us do, you might want a hot drink and sleeping bag handy once you're hooked! ). We are a friendly bunch.

It is not invasive for me in the Pacific Northwest. : )

Not invasive for me neither!

@JRsbugs
I didn't expect forum members to email me directly, but a "forum" often sends you a notification mail when someone has replied to your thread. Anyway, I'll get my self a sleeping bag :-)

If it's not invasive in the UK, I doubt it will be just on this side of the North Sea... Thanks again!
