This is a European linden, Tilia platiphyllos. Today we have defoliated all the lindens and this one was also a candidate. Alex did the main work and I only did the nitty gritty final enhancement.
Two or even more equally alid frotns don't surprise anymore. This is to be expected on a tree in the naturalistic style. The form is the informal broom form btw. (don't confuse style and form!)
