The North Texas Trend Toward Dark, Modern Landscapes
Black and charcoal aggregates are having a moment in DFW. At Outdoor Warehouse Supply, we help homeowners, contractors, and designers choose the right dark material for both style and performance. They sharpen concrete, cool off warm brick, and frame plants with crisp contrast. The challenge is choosing the right material for the job. Should you use Black Star gravel, black decomposed granite (DG), or dark river rock? Each has a different look, feel, and performance profile in our heat, clay soils, and storm cycles.
This guide compares appearance, sizing, installation, drainage, maintenance, and where each product shines so you can design once and enjoy for years.
What They Are
Black Star
A crushed, angular basalt-like gravel with consistent charcoal to jet black tones. Because it is angular, it locks together under foot traffic and resists rolling, and it lives in our river rock, sand & gravel family for easy ordering.
Black DG (Decomposed Granite)
A very fine, gritty aggregate that compacts into a firm, stable surface. With stabilizer, it becomes a semi-solid path or patio. Colors range from charcoal to near black depending on quarry and moisture. You can source DG, base, edging, and stabilizer in one stop from our products catalog.
River Rock (Dark Mixes)
Rounded pebbles and stones graded from 1 inch to 3 inches or larger. Polished by water, they read soft and natural. Dark blends lean graphite and deep brown with occasional lighter accents. Browse current sizes and blends under river rock, sand & gravel.
The Look: Color, Texture, and Scale
- Black Star has a matte charcoal finish that photographs consistently. Angular faces catch light and create a subtle sparkle without looking glossy.
- Black DG reads as a continuous, monolithic color field. The texture is tight and fine. This is the right choice when you want a smooth, modern plane for paths or minimalist courtyards.
- River rock introduces rounded forms and variation. It is best when you want movement and a natural, creek-bed feel that still trends dark.
Coordinating With Architecture
- White stucco, black frames, and cedar accents: Black Star adds crisp definition around beds and steel edging. Black DG gives a gallery-style courtyard surface.
- Red brick and painted trim: Dark river rock cools the palette and softens hard lines around columns and downspouts.
- Mid-century concrete and low plantings: Black DG highlights geometry. Finish with clean steel or aluminum edging.
Sizing and Foot Feel
- Black Star is often stocked in 3/8 inch and 5/8 inch. The 3/8 inch size compacts more and tracks less. The 5/8 inch reads bolder and is ideal for parking strips and wider beds.
- Black DG is a fine mix. With stabilizer and proper compaction, it supports carts, strollers, and dining furniture. Without stabilizer it remains permeable and soft underfoot.
- River rock begins around 1 inch and goes up. It is not comfortable for frequent walking. Use it as a decorative band, against foundations, or where you want strong texture.
Installation Overview
Base preparation
North Texas clay moves with wet and dry cycles. Scrape organics, grade for drainage, and compact subgrade before you pour base material. A non woven geotextile underlayment helps control weeds and stops fines from migrating, and you can pick up fabric, base rock, and edging right from our products aisle.
Black Star
Set steel or aluminum edging from our products section. Place 2 to 3 inches depth and rake even. A light plate compaction sets the surface. Topping up after the first storm season is normal.
Black DG
For pathways and patios, excavate 4 inches or more. Install 2 to 3 inches of compacted crushed base, then 1 to 2 inches of DG. If you are using stabilizer, follow the water blend rate and compact in thin lifts; use the landscape materials calculator to dial in volumes before you schedule delivery. Crown or cross slope the surface so water never sits.
River rock
Use as a decorative layer over landscape fabric or as a splash band under rooflines. For dry stream beds, shape a shallow swale, set larger anchor stones first, then infill with graded river rock for a natural taper — and skim our project gallery for layout ideas that handle runoff cleanly.
Drainage and Heat Behavior
- Black Star drains well and does not hold heat as aggressively as black concrete. Mid-project designers often confirm finish temps with shade planning and surface choices per EPA heat island research. It will warm in summer sun but cools quickly overnight.
- Black DG is permeable when unstabilized. With stabilizer, it still allows modest infiltration but needs a positive slope so water does not pond. Avoid flat low spots.
- River rock is very free draining. In high flow locations add a granular base to prevent undermining and keep the set stable during big storms.
Maintenance Reality Check
- Black Star: Rake leaves with a rigid rake, blow gently to avoid scattering. Top up thin areas seasonally. Weed pressure is low with fabric and clean edges.
- Black DG: Expect occasional re-brooming of fines, especially after heavy storms. If stabilized, patch cracks by wetting the area, adding fresh mix, and compacting with a hand tamper.
- River rock: Debris collects between stones. Use a blower and hand pick in tight spots. If the rock sits under trees, a fabric layer makes cleanup easier.
Cost and Value
Costs vary by quarry and haul distance. As a rule of thumb, DG is the budget choice for large ground planes, Black Star is mid tier with a refined look, and river rock is most efficient when used as an accent because of depth and weight requirements. Delivery access, distance from the street, and the need for base preparation will influence the total project cost more than the rock choice itself; check current drop options on our delivery page.
Where Each Product Shines
- Use Black Star to frame beds, define xeriscape zones, and modernize curb strips. It pairs well with steel edging and upright grasses like ‘Karl Foerster’ and with architectural agaves.
- Use Black DG for walkable surfaces, patio infill around large pavers, bocce or fire pit pads, and minimalist courtyards. Stabilizer helps when furniture or frequent foot traffic is expected.
- Use dark river rock as a foundation band to manage splash, in dry creek concepts, or as a high contrast border where you want softer forms.
Simple Palettes That Work
Minimal courtyard
Black DG surface, concrete stepping stones, low boxwood or dwarf yaupon, and one feature olive or desert willow. Add low-voltage path lights with warm temperature to prevent a cold look at night.
Front yard refresh
Steel edging, 3/8 inch Black Star in beds, drought tolerant shrubs, and a ribbon of 1 to 3 inch dark river rock against the foundation to control splash.
Entertaining area
Stabilized DG for the main pad, Black Star in surrounding beds, and larger river cobbles in a dry stream that directs gutter downspouts to a rain garden.
Common Mistakes to Avoid
- Picking a size that fights the use. Large river rock on a primary path looks great but feels awkward.
- Skipping edging. Dark aggregates look best with crisp boundaries.
- Ignoring slope. Dark surfaces show ponding. Give water a route out of the space.
- Overusing one texture. Contrast looks modern when you balance two or three textures, not five.
Quick Comparison Table
| Feature | Black Star | Black DG | Dark River Rock |
| Texture | Angular, matte | Fine, compactable | Rounded, varied |
| Foot traffic | Good for light to moderate | Excellent with stabilizer | Poor for frequent walking |
| Drainage | Very good | Good to very good | Excellent |
| Best uses | Beds, bands, strips, mulch alternative | Paths, patios, paver infill | Accent bands, stream beds, splash zones |
| Maintenance | Light raking, occasional top up | Re-brooming, patching if stabilized | Blowing, hand pick debris |
How to Order and What to Ask
- Measure length and width for each area. Multiply to get square footage and match to the target depth to estimate volume, then confirm tonnage with our landscape materials calculator.
- Note access. Can a truck reach the drop zone or will you need wheelbarrow runs from the driveway.
- Decide on edging and fabric types. Bring a quick sketch or photos and we will confirm quantities.
- If you are mixing products, bring a sample of nearby concrete or pavers so we can compare tones under natural light.

FAQs
Will these dark rocks fade?
Black Star weathers slightly and looks richer when rinsed by rain. DG darkens when damp and lightens as it dries. River rock stays consistent. Occasional rinsing restores color.
Can I mix Black Star and Black DG?
Yes. Use DG for the walkable plane and Black Star to frame beds and edges. Keep the border at least 6 inches wide so it reads intentional.
Is fabric always required?
For decorative beds and bands, fabric reduces maintenance. For stabilized DG paths, fabric stays out of the top layer and belongs under the base.
How deep should I install river rock?
Two to three inches for bands and more for stream beds. Use larger anchor stones if you expect fast runoff.
