Definitions of Wallflower:
"a person who sits by the wall at a dance because no one has asked them to dance"
"a shy person, especially female, who ... does not attract much attention".
On top of a stone wall along the old cemetery, these tiny yellow flowers are now in bloom. I did not know their name, but put my photo into Google Image Search, and found that their Latin name is Phedimus hybridus or Sedum sibericum (English: Siberian Stonecrop; Swedish: Sibiriskt fetblad.)
A bit further on, a taller and older part of the wall is totally covered by these big old Hydrangeas - or Hortensias - which really don't fit the symbolic definitions of wallflower, as they are rather majestic... They are still flowers growing on a wall, though! ;-)
