White English Bluebell or something else?
These exquisite little white plants have popped up in a pot on my patio this year and are just opening. They look like a bluebell - but not like the other bluebells in my garden. I don’t ever buy bulbs so I’m rather confused as to what they are and where they came from! The flowers have a delicate green ‘stripe’ inside the flower cups. Can anyone help with identification please?
