Hi,

I was gardening in a T-shirt, wearing gardening gloves, and a weed
cutting fell on my wrist. There was no immediate reaction but the
next morning it got very itchy and came up in blisters, and took over
a week to go away.

I've heard about poison ivy, but I thought that was an American plant.
What are the plants in the UK I should be wary of, besides nettles?
It didn't look like giant hogweed, and was quite small.

Thanks,
Dave.
