Buying Guide: Key Purchase Considerations

  • Sun exposure and moisture: Verify that the plant tolerates full sun and has appropriate drought handling for your climate. Hydrangeas and azaleas benefit from consistent moisture and mulch in hot regions.
  • Hardiness and zones: Choose varieties aligned with your USDA zone to ensure winter survivability and steady growth across seasons.
  • Growth habit and spacing: Plan for mature size to avoid crowding features such as sidewalks, windows, or other shrubs.
  • Soil and maintenance: Ensure soil drainage is adequate and consider pruning needs. Some plants require minimal pruning, while others need occasional shaping after flowering.
  • Bloom period and color: Mix evergreen shrubs with flowering perennials to achieve continuous interest; consider pollinator attractiveness when selecting varieties.
  • Fragrance and wildlife appeal: Fragrant gardenias can enhance sensory appeal, while nectar-rich azaleas attract hummingbirds and butterflies.
