What Landscaping Zone Are You in — and Why Does It Matter?

If your plants keep dying or struggling through Long Island winters, hardiness zones might be the answer. Long Island falls primarily in USDA Zone 7a–7b — which means cold winters (as low as 0–10°F) and warm, humid summers. Knowing your zone changes what you plant and when you plant it.

What Zone Is Long Island?

Most of Nassau and Suffolk Counties fall in Zone 7a or 7b. The North Shore tends to be slightly cooler; the South Shore and coastal areas are a bit warmer. This matters for anything you're keeping year-round — trees, shrubs, perennials, and ornamental grasses all have zone requirements.

Best Plants for Long Island Landscapes

• Ornamental grasses — drought-tolerant and low-maintenance in Zone 7
• Knockout roses — disease-resistant and reliable in this climate
• Boxwood — classic hedge material that handles Long Island winters well
• Japanese maples — thrive in Zone 7, stunning fall color
• Blue Star juniper — evergreen, low-maintenance, great for borders
