This is a review of the solid perfume - I'm not sure if the weird-looking spray still exists.
As promised, it's quite green. There's that sweet grass smell you get when neroli and vetiver meet, but there's also an evergreen tone to it as well. There's a tart citrus on top, and some cooking spices in there as well, but it all sums up to equal "green".
The most notable foil to all that green is the tarragon note that Lush seems to like. It comes across as sort of creamy and foody. I don't really love that tarragon, but I can see how Go Green needs something to add non-green depth.
It's all fairly linear once the citrus burns off - a neroli/vetiver mix that smells kind of like a freshly moved lawn on a hot day, but in a forest, and with that weird tarragon in there as well.
All in all, I don't dislike Go Green, but there are better greens out there, and the linearity makes it a bit of a drone. A fantastic chypre base or something could have really made this sing, but instead, it just hums along...
