Natural - De-fences
Hiding our horrible but practical back fence, which every garden has here - its made of asbestos, is my natural form of defence against anyone trying to scale the fence. It's our blackberry bush. Some years it produces enough fruit to freeze, other years, two berries and its done. The climate here is actually too hot for a good crop, but at least it survives our summers.

And the pumpkins aren't really doing much better, just providing us with some greenery. We grew one large pumpkin last year, which ripened in February! A tad too late for Halloween?

Purple flowers on the trellis, look like tiny purple cups. Once they ripen, they have tiny green berry seed pods.
