Tree Buds and Forest School Wilderness

I wanted to take some pictures for you all of our beautiful trees with flowering buds and catkins. Can you figure out which trees they are? It starts off with the walnut tree (next to the wild bit by the veg garden). It has the most amazing catkins, I'd like to find out more about how they change into walnuts and look forward to tracking their growing journey. Can any of you find out and let me know? The grandmother tree was looking so beautiful with fresh bright green leaves. I'm amazed how quickly the horse chestnut / conker tree gets its chandelier of amazing flowers, can you find one and look at them close up? They are so beautiful! I highly recommend it! There is also the pretty purple vinca flowers which like growing in the shade, some of you picked them to decorate your fairy houses. There's our baby elder tree develping flower buds next to the trading centre tree trunk, there's some lovely fresh nettles, lots of alexander weed and it's all looking so wild and wooly without you all playing there every week but the plus side is that I think it's definintely meant more wildlife is moving in, though the weeds are going bananas. Maybe we can find more uses for our weeds!?
