I have gone all natural, as there is so much just springing up in my garden, and the park. But go to the link above to see what others have come up with, and perhaps post your own!
The willow trees are always first out in the park, and I love the lovely lime green of the young leaves.
Another acid green is the Euphorbia in our garden. It tends to spread everywhere, but I dig up the unwanted bits and let the rest wander. It is a really bright colour in dark places!
I thought my hostas in pots had died after the exceptionally wet winter we had, so I was delighted to find these shoots coming up strongly!
The lovely yellow tulips come green first as they break out of the buds.
Enjoy the green of Spring and taker your camera. (Sorry if you are in the Southern Hemisphere!)
