Small Shrubs for Western Exposure in Chicago Suburbs

Replacing yews with colorful dwarf shrubs on a west-facing site in Chicago's south suburbs (zone 5b). Candidates: Weigela 'Carnaval', Daphne 'Carol Mackie', Mountain Laurel (Kalmia latifolia).

Site Considerations

  • Western exposure: Intense afternoon sun, drying winds, potential winter desiccation.
  • Soil: Often clay; amend with organic matter for drainage.

Plant Evaluation

Better Alternatives for West-Facing Clay

  • Dwarf Korean Lilac (Syringa meyeri 'Palibin'): Fragrant, powdery mildew resistant, 4–5 ft.
  • Spirea 'Double Play' series: Colorful foliage, reblooming, tough.
  • Potentilla fruticosa cultivars: Long bloom, drought-tolerant once established.
  • Hydrangea paniculata 'Bobo' or 'Little Quick Fire': Sun-tolerant, compact, reliable blooms.

Water deeply during dry spells; mulch to conserve moisture and moderate soil temperature.
