It even tells hoe to use stone sizes to create the illusion of fast-moving water and slow moving water...
Use rocks to create interesting effects, such as the dry pond in the photo at right. This was made with Mexican river rock and oolite (coral rock) stepping stones. There is a Clusia nana on the volcanic rock in the middle of the pond. This landscaping feature needs neither irrigation nor fertilizer!
Stone is a very important feature in a Japanese Garden. Dry landscape gardens sometimes contain little more than carefully place rocks set in a ‘sea’ of gravel. Stones can point upright, symbolising mountain peaks or be laid on their sides to form a bridge. The Japanese never use a ‘diseased’ stone which is misshapen on top, or a ‘dead’ stone which is an upright stone laid horizontal, or a ‘pauper’ stone that has no visible relationship with other stones. Stone placement today still follows principles laid down over a thousand years ago.
A dry slate gorge represents a watercourse in our garden and a boulder bubbling water symbolises an active volcano. Raked gravel represents waves and the sea.

I saw some growing wild near the railway lines, and I fell in love. I had to have them !
But, as they say, in germany "everything that is not permitted is prohibited" , so I planned to do it on a Sunday morning, when nobody will be around.
Had a tough time digging them up from the gravelly ground, and carrying them back. I divided the clump and planted them at the back of my perennial border, and a few other places.
The elderly man working in the neighbour's garden came to have a look. His comment : "Weeds."
They seem to be undemanding so I hope they'll do well. I'm a bit worried that they are invasive. If they spread around a bit, that's great, but I don't want them to overtake everything.
Goldenrod planted behind my lily, which BTW is not doing well... I don't know why...
The hollow had been full of sand, now it's overgrown. I plan to fill it with white stones, and make a "dry" pond. The Goldenrod is on the left, it looks nice against the backdrop of the Buddleja (which BTW I didn't know enough to prune this spring).
This is my inspiration:
