Daffodils in June

Here is a charming photo which I took on the afternoon of Friday 1 June. It shows daffodils growing in a cottage garden in the foothills of the Cairngorms. Note, that they were not all fully in bloom!

We have wonderful regional variation in the UK, from the early daffodils of Cornwall and the Scilly Isles, to these late daffodils of Northern Scotland. I wonder, when did the earliest Cornish daffodil bloom, and when will the latest Scottish daffodil bloom?
