Oh Neil ,
I am easily confused, just spent twenty minutes on the cottage garden cubit looking for this thread .
I was in a hurry earlier today and should no better than to jump to conclusions without proper research. Is the plant above a Cercis Silliquastrum ?
When I typed in Judas tree all the answers but one in the DG plant files said Cercis Canadensis.
With further research I see that the Cercis silliquastrum is a native of your country.
I also discovered numerous references to eating the flowers, is this something you have done and would you recommend trying them?
