Permaculture garden

Exploring Jan and Ken's permaculture garden. The garden has paths which take the longest way between two points, providing glimpses of surprising plant life before wending down to a waterfall. A caterpillar is frozen in the act of breaking out of the ground - and is really a frond of fern.
The paths are named after Ken and Jan's grandchildren, who proudly display their piece of Eden to visitors.
Everything is lush, everything is green. Everything is compost.
