Mimosa o Albizia.

Also known as the Silk Tree,  this monster was growing with a lot of other wild shrubbery on a patch of earth outside the Vet's. Luna was taken there for her second Kennel Cough jab. She's had about 5 assorted vaccines now, with a different booster due in 2 weeks and still the compulsory Rabies one and microchipping to come. Puppies are massively expensive to run even when they're not sick.
The extra I think might make a good if challenging jigsaw.
