Marks & Spencer has apologised after displaying daffodils alongside spring onions in one of its stores.
The flowers, which can be poisonous if eaten, were displayed in the fruit and veg aisle under a "seasonal favourites" banner.
Botanist and presenter James Wong drew attention to the display on Twitter, warning that eating daffodils "is like swallowing a box of tiny needles".
An M&S spokesperson said it was a "genuine error in one of our stores".
Daffodil stems, which are widely sold in supermarkets at this time of year, can bear a resemblance to some vegetables at first glance.
Public Health England
wrote to retailers in 2015 warning about the potentially nasty consequences if there was a mix-up with how they are labelled.
It said they contain toxic alkaloids which can cause severe vomiting, noting 27 poisoning cases in the previous year.
