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

If your plants keep dying or struggling through California weather, hardiness zones might be the answer. the South Bay falls primarily in USDA Zone 9b-10a - which means mild winters (as low as 30-40°F) and warm, humid summers. Knowing your zone changes what you plant and when you plant it.

What Zone Is the South Bay?

Most of Santa Clara and San Mateo Counties fall in Zone 9b or 10a. The inland areas tend to be slightly warmer; coastal areas 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 the South Bay Landscapes

• Ornamental grasses - drought-tolerant and low-maintenance in Zone 9-10
• Knockout roses - disease-resistant and reliable in this climate
• Boxwood - classic hedge material that handles California weather well
• Japanese maples - thrive in Zone 9-10, stunning fall color
• Blue Star juniper - evergreen, low-maintenance, great for borders
