Heat‑Loving Annuals for Poolside Planters in Pennsylvania

16 Planters, Full Sun, Low Maintenance

For 10.5″ deep × 48″ long planters around a hot pool in western PA, choose sun‑tolerant annuals that handle reflected heat and occasional splashing.

Recommended Annuals

• Marigolds – French or African types; tough, pest‑resistant, all‑summer color.
• Petunias (wave or spreading) – cascade over edges, bloom nonstop.
• Vinca (Catharanthus) – glossy leaves, heat‑proof, no deadheading needed.
• Zinnias (Profusion series) – mildew‑resistant, compact, vivid colors.
• Sweet William (Dianthus barbatus) – fragrant, cool‑season but lasts into summer.

Foliage Accents

Gold‑leaf Hosta (not blue‑leaf) adds contrast and tolerates sun. Dusty Miller or ornamental sweet potato vine for trailing silver/purple foliage.

Critical Care

• Mulch 2 inches to keep roots cool and moist.
• Water deeply daily in July/August; consider drip irrigation.
• Fertilize with slow‑release at planting + liquid feed monthly.

Mix 2‑3 varieties per planter for a dynamic, season‑long display.
