Why This Planting Plan Works for a Grey House
Grey exteriors are a perfect backdrop for garden colour because they’re neutral. This plan uses:
- Purple + burgundy to create a strong contrast
- White blooms to brighten the foundation line
- Evergreens for year-round shape (even outside bloom season)
- Mixed foliage textures, so the garden still looks good between flowering cycles

How to Plant This Garden
1. Know Your Soil
Good soil is the foundation of a healthy garden. To achieve the perfect “garden loam,” you need a balance of organic matter (humus) and minerals (sand, clay, silt). Before planting, we recommend analyzing your soil and amending it with compost if necessary. Visit our website to discover The Many Benefits of Mulching.

2. Calculate Your Spacing
How many plants do you need? While spacing is a personal preference, planting closer together gives instant full coverage, while spacing further apart requires patience.
Use this simple calculation to estimate the number of annuals needed for full coverage:
- Calculate Area: Multiply the length by the width of your garden bed to get the Square Footage.
- Multiply by 4: This is the approximate number of plants needed.
Example: A bed that is 4 feet long x 3 feet wide = 12 sq. ft.
12 sq. ft. x 4 = 48 plants needed.

3. Planning the Layout
If you are a beginner, it helps to draw a rough plan on paper before digging. Follow these design principles for a professional look:
- Height: Arrange taller plants (Dracaena, Shrubs) at the back or center, and shorter flowers (Pansies, Alyssum) at the front.
- Form & Texture: Mix broad leaves (Hostas) with fine needles (Juniper) to create visual interest even when flowers aren’t blooming.
- Groupings: Avoid planting “one of everything.” Plant in groups of 3 or 5 for a cohesive drift of colour.
