this plant is growing in my neighbours garden. Can anyone identify it for me please.
It is a wild arum. Here is a site that tells you about it.
Hi Shelley, it's Lords & Ladies aka Cuckoo Pint (Arum maculatum) a British wild plant. The poisonous berries contain seeds which make this plant spread rather invasively, so I always remove the stems as soon as the berries look like they'll start falling, but do leave them as long as possible to admire their beauty.
Thank you xxx
