Rocks - then & now
These are pictures of a rock arrangement in the Tea Garden of the Nitobe Memorial Garden in Vancouver.
In the left-hand picture, the rocks (in 1970) look much the same colour as rocks I've seen locally when they were newly excavated. The same rocks have later shown up - after a thorough hosing down - as blue as the rocks in the right-hand picture. The right-hand picture was taken today.
Apart from the rocks' change of colour, the most noticeable change is that the hedge has been removed. The ground cover is different too.
