8 Criteria for Choosing Your Plants

A successful landscape starts with a careful selection. To achieve the desired effect and ensure healthy growth, evaluate every specimen using these essential criteria. Here is how to simplify your choices for a top-quality gardening project.

Coordinate Blooms and Colours

Flowers create the strongest visual impact. Orchestrate a dynamic flow of colours from spring until frost by focusing on bloom periods and colour palettes. Proper planning ensures a vibrant garden all season long.

Maximize Visual Impact

  • Create contrasts to catch the eye (e.g., bright red and pale yellow).
  • Adopt a monochrome theme for a soothing atmosphere (e.g., shades of pink).
  • Use a dominant colour with complementary accents for perfect balance.
  • Integrate grey foliage to soften bold contrasts.

Play with Foliage Textures

Foliage provides permanent structure even when plants are not in bloom. Textures influence how space is perceived:

  • Fine foliage: adds lightness (e.g., 'Suncole' Honeylocust, Gleditsia triacanthos).
  • Dense foliage: provides a solid, massive look (e.g., Western Red Cedar, Thuja occidentalis).
  • Variegated foliage: brightens shady areas (e.g., 'Elegantissima' Dogwood, Cornus alba).
  • Fall colours: create a living painting (e.g., Serviceberry Amelanchier, Red Maple Acer rubrum).

Anticipate Size and Habit

Always check the mature size of a plant to avoid crowding its neighbors. For limited spaces, read our article on choosing trees for small yards.

The habit defines the natural silhouette of the plant. Choose a shape (pyramidal, weeping, globular) that fits your plan naturally without the need for constant corrective pruning. For instance, a Ginkgo (Ginkgo biloba) offers a distinctive pyramidal habit from a young age.

Analyze Soil and Exposure

Soil drainage and pH directly influence root vigour. Compact or acidic soil can hinder the establishment of certain species. Bring a soil sample to your local garden centre for an accurate analysis before investing. Also, respect light requirements:

  • Sunny: 6 hours or more of direct sun.
  • Partial Shade: 3 to 6 hours of sun or dappled light.
  • Shade: less than 3 hours of direct sun.

Evaluate Maintenance and Hardiness

Select plants whose requirements match the time you wish to invest. Some plants require winter protection or specific fertilization. Prioritize hardy varieties suited to your zone (3, 4, or 5 in Quebec). Discover our recommendations in this complete guide to perennials.
