More Autumn in the garden

The garden continues to change colour as autumn gathers pace. The field maple trees that I planted are still small but already we are rewarded with some lovely golden yellow leaves. I walked around the garden yesterday taking photographs and then decided it was an ideal time to wash the greenhouse down. But while I was doing this the sky clouded over and it began to rain - cold, icy rain. Then it started to snow. "It won't settle", we said. But it did! Snow in October..... how unusual is that? Is it a sign that we are in for a long cold winter or is Mother Nature just playing a few tricks on us?
