Hi, any ideas what this is please?
It is a plant called Pokeweed, properly Phytolacca americana. The flowers are replaced by black berry like things which are toxic if eaten. I like the plant, but others don't. So a weed? That depends on whether you like it, or want it.
I like it too. It can self seed when happy but it's easy to pull up unwanted babies. Birds love the seeds but they're no good for humans, pets or livestock. I've never had any problems.
Thanks Berghill, I'll let it do it's thing then despatch it to the great compost bin in the sky - or force feed it to the wild rabbit that's eating everything in the garden except this. Thanks again
Those who are visiting here http://www.e-ruston-oldvicaragegardens.co.uk/pages/view/562/gardens.htm on the 19th July can expect to see lots of Pokeweed in the wilder parts of the garden, under the big shelter belts of Monterey Pine.
