Rock Garden Design

Every Kamloops yard has a dry, awkward corner where nothing thrives — baked by summer heat, starved of moisture, and often full of gravelly, alkaline soil. A rock garden turns that “dead space” into a deliberate, drought‑smart feature using stone, gravel, and plants that love Kamloops conditions.

Anchor with One Strong Boulder

Start with a single boulder 2–3 feet across. Bury the bottom third to make it look natural and to stabilize it through freeze–thaw cycles. Build the rest of the layout around this anchor — it sets the tone and scale.

Set Every Stone Deep

Soils shift with spring thaw. “Plant” each rock one‑third into the soil so it stays put and looks like part of the landscape rather than placed on top.

Cluster in Odd Numbers

Group stones in threes, fives, or sevens. One large boulder with two mid‑sized companions and scattered cobbles creates a natural rhythm that suits dryland design.

Use the Slope

If your corner has any grade, mimic nature:

• Large stones low
• Smaller stones higher
• Finish with pea gravel or chip at the top

This improves drainage — essential in Kamloops’ soils.

Rely on Sedum

Sedums are Kamloops champions. They thrive in heat, survive drought, and come in chartreuse, burgundy, blue‑green, and silver. They soften edges and fill gaps without irrigation.

Recommended hardy sedums:

• Sedum spurium
• Sedum reflexum
• Sedum acre (use sparingly; spreads fast)

Add Silvery Mediterranean Herbs

These herbs love lean soil, sharp drainage, and full sun .

• Lavender
• Russian sage
• Artemisia
• Santolina
• Creeping thyme

Their scent and silver‑blue foliage elevate the space while staying drought‑friendly.

Tuck Hens and Chicks into Crevices

Sempervivum rosettes nestle between stones, spread slowly, and come in colours from green to burgundy to near‑black. They’re nearly indestructible in Kamloops heat and cold.

Choose One Focal Plant

A single standout plant gives structure and prevents the garden from looking scattered.

• Yucca (thrives in heat; extremely drought‑tolerant)
• Mugo pine
• Dwarf blue spruce
• Specimen juniper

You can add a potted agave for summer only — bring it indoors before frost.

Add One Ornamental Grass

Choose grasses that are non‑invasive and hardy in the Kamloops area.

• Blue oat grass (Helictotrichon sempervirens)
• Little bluestem (Schizachyrium scoparium)
• Prairie dropseed (Sporobolus heterolepis)

Avoid Mexican feather grass — it’s invasive in BC.

Consider a Dry Riverbed

A meandering band of mixed cobbles guides the eye and channels runoff during heavy rain. Kamloops’ sudden downpours make this both beautiful and functional.

Commit to One Stone Palette

Pick one tone family:

• Warm (tan, buff, rust)
• Cool (gray, blue, black)
• Neutral (cream, white)

Consistency makes the design feel intentional and calm.

Raise the Bed Slightly

Mound the planting area 4–8 inches above grade. This improves drainage — the #1 success factor in Kamloops rock gardens.

Build the Hidden Layer

Under the surface, create a drought‑smart base:

• Soil blended with compost
• Topped with gravel and coarse sand

This fast‑draining mix prevents root rot and supports heat‑loving plants.

A Dry Corner Becomes a Designed Feature

Rock gardens turn limitations into style. Start with one good boulder, choose a unified palette, and let sedum and sempervivum fill the gaps. Within a season, the space reads as a deliberate, low‑water garden feature rather than a problem spot.
