No, this is not my favourite Silver Linden (Tilia tomentosa), but another species (Tilia platyphyllos?) that goes into bloom earlier. I noticed the first open flowers on this tree on 15 May, and I think it was still too early, but maybe that was due to the short period of almost-summer weather we had before the rains began. I didn't manage to get a single photo in focus back then because of that notorious wind that kept moving the the branches, so here is what I have of a later stage.
The leaves of this species don't have the silvery undersides, and the stamens of the flowers have so long! They smell different fro Silver Linden flowers too.
