My eyes turn to paving and paving details, wherever I go -
I notice the patterns, the joint widths, the materials and the edging.
Does that sound boring? Well, at least, I always have something to look at. :-)
The stone paving that is the most fun is PEBBLE MOSAIC paving.
I first saw pebble mosaic many years ago at the public garden, Dumbarton Oaks, in Georgetown in Washington, DC. Beginning in 1959, Ruth Havey and Mildred Bliss, the property owner, transformed an area that was meant to be a tennis court into a pebble mosaic garden. The pebbles were imported from Mexico and were set into “distinct patterns and colors, in the Italian manner.” It is an intricate design with curved limestone edgings enclosing beds of low growing thyme and sedum. The shallow pebble pool was meant to be covered by a thin layer of water to bring out the glistening colors, but is now dry.

The nest amazing example of pebble mosaic that I saw harks back to historic paving found in the Spanish Moorish era. It is the immense Plaza de España in Seville, Spain. I remember going there and just staring at the paving - the tilework, architecture, waterway are also marvels and are lauded- but no one seems to mention the pebble paving. It is quite extraordinary.

And pebble mosaic is not just found in Southern Europe - traditional Chinese gardens also utilized pebbles in their paving in elaborate ways. They were a defining feature in a Chinese garden. The classic reference, The Oxford Companion to Gardens, describes the paving in their description of a journey in a Chinese garden,
‘and the visitor is led on through them, not only by pebble-patterned pathways and open doorways…, but by the constant suggestion of something new and delightful…”
Ah, pebble-patterned pathways, such a great idea for several reasons. Paths and terraces with decorative, rounded pebble patterning or paving were indispensable because, not only were they beautiful, but, in the high heat of summer, the gardener might splash a few buckets of water on the walks. The water sits beneath the top of pebbles and cools the garden through evaporation. People could stroll on the raised paving without getting their shoes wet. It is an ingenious way to provide evaporative cooling to an outdoor space!

Now, all this intricate pebble work may seem daunting but you can simply add brightly colored stones in a random pattern in a garden path. I took this photo at the Sam Maloof Foundation gardens. A good example of the beauty of stones and stone paving:

Probably the best known and prolific pebble mosaic artist in the U.S. is Jeffrey Bale. He writes about his discovery of pebble paving, "Then I discovered pebble mosaic as an art form when I journeyed to Spain and Portugal. I had no idea that pavement could be so beautiful. The Plaza de España in Sevilla is carpeted in acres of river pebbles set in waves, and the sidewalks of Lisbon swirl with exquisite black-and-white patterns....”
Balewrote a detailed explanatory article for Fine Gardening magazine on how he actually installs pebble mosaic paving. He lists the process and the materials. It is a master class in how to actually do it. Here is the link to Jeffrey Bale’s article.

I hope you enjoyed this post about pebble paving! There is s much to know about this. Portugal is also known for its stone paving too. BTW, I am the host for an

Great post and subject - very inspiring. I do admire pebble paving. I must look up Jeffrey Bale’s work. Here in the UK we had the amazing Maggy Howarth, who sadly died this year. I was fortunate to see her design at Bonnington House near Edinburgh - her work is worth checking out online.
I believe the Asian garden in the Denver Botanic Gardens (one of my most favorite public gardens) also has beautiful pebble paving.
