It's one of the taller Campanula family.

Thankyou very much, I just googled blue bell type flower and I thought I had come up with agapanthus! Glad I checked back here as I wasn't sure, cheers Louise1!

This is the English Harebell ( aka Scottish Bluebell); Campanula rotundiflora.

I love these, they are so dainty - wish they grew round here!

Oh thankyou, I said Harebell at the start, but neighbour said not! Ha!, was right for a change.. Cheers Bulbaholic.. and yes Steragram, I agree they are really delicate. Another question, Mr B, do they grow from bulbs then?

No, Mazzie, they don't grow from bulbs. This is the plant that I use in my arguments for using the scientific name rather than the common name. The Scottish bluebell is actually a campanula, just the same fiberous rooted plant that we grow in our gardens. The English bluebell is a hyacinth (Hyacinthoides non-scripta) and grows from a bulb.
