1. Polished black pebbles: the essential choice

Polished black pebbles the essential choice

Polished black pebbles are the most in-demand stones for contemporary landscaping. Their smooth and shiny surface contrasts with vegetation and reflects natural light. These fully black stones, without streaks, are available in sizes from ½ inch to 4 inches. They work just as well in a modern flower bed as around a pool or in a zen garden.

Driveways and garden bed borders particularly benefit from this type of finish.

most architectural styles. Their semi-polished finish and nearly symmetrical shapes create a clean look without appearing artificial.

Sizes range from ½ inch to 6 inches, allowing for customized compositions. These neutral tones match current palettes focused on organic colors. In a minimalist design, a rock garden or a transition zone between plant areas, they integrate effortlessly.

3. Slate chips: texture and character

add character thanks to their flat texture and irregular angles. Parks Canada also recommends using decorative stone mulch to reduce fire risks and limit maintenance around buildings.

Dark gray to black when wet, these stones from 1 to 3 inches create natural paths and defined borders. Their flat shape makes them stable underfoot. And unlike round pebbles, they do not roll under weight. A 40 lb bag provides good coverage for a garden path or a walkway.

4. Decorative gravel: drainage and finish

6. Engraving stones: durable personalization

custom space. Their flat and smooth surface allows engraving names, dates, messages or patterns using an electric engraver or sandblasting.

Slate black or light gray, matte or highly polished finish: the choice depends on the desired contrast with the engraving. Sizes range from 1 to 4 inches for small labels up to 4–6 inches for more visible commemorative stones. They are used to mark a garden entrance, identify plantings, create memory stones or personalize a meditation space.

But be careful: not all stones engrave equally well. Stones selected for engraving have a uniform surface and density that allows engraving without crumbling.

7. Crushed glass: shine and light

captures sunlight during the day and the glow of flames at night. Reflective black, transparent or colored, it is available in sizes from ¼ to ½ inch.

FAQ

What depth of decorative stones should be planned? A depth of 2 to 3 inches is recommended for most applications. This thickness ensures full ground coverage and prevents weeds from growing through.
Do the stones withstand Quebec’s climate? Yes. Natural stones withstand freeze-thaw cycles. They do not crack and retain their color over time.
Is a membrane needed under the stones? A geotextile fabric is recommended. It prevents weeds, stabilizes the stones and prevents them from sinking into the soil over time.
Can different colors be mixed? Yes. Black pebbles with beige stones create a strong contrast. Crushed glass adds luminous reflections.
How to maintain decorative stones? Rinsing with a garden hose is usually sufficient. For stubborn stains, a stiff brush and clean water work well.
