I’m sure Shakespeare or somebody must have written about the joyful face of the humble primrose.  If not, he/she should have!

P.S. a few minutes of Google and this I found (I’m feeling poetic now):

Ring-ting! I wish I were a primrose,
A bright yellow primrose blowing in the spring!
The stooping boughs above me,
The wandering bee to love me,
The fern and moss to creep across,
And the elm-tree for our king!

William Allingham
