Need coastal and road salt-resistant varieties for your garden?
At Nature Hills, we frequently receive questions about salt-tolerant plants for specific locations.
Gardeners often ask: "What plants thrive in salty conditions? Which salt-resistant trees, shrubs, perennials, and bushes perform best?"
This question comes from a surprisingly wide range of areas. Beyond the obvious coastal regions: Florida, the Gulf Coast, South Texas, and California. But we also hear from unexpected places like Minnesota, Chicago, and Pennsylvania!

Why Salt Tolerance Matters Beyond Coastal Areas
The salt challenge in inland areas isn't from ocean spray: it's from road salt buildup during winter de-icing operations. This road salt can be equally damaging to plants as coastal salt spray.
When salt contacts plant leaves or washes into soil, it creates a process where salt leaches water from plant tissues. This dehydration eventually kills plants that lack salt immunity. Understanding this process helps gardeners choose appropriate salt-resistant landscaping solutions.
Top 10 Best Salt-Tolerant Plants For Your Garden
If your garden battles ocean spray, salty winds, or soil laced with salt, these top salt-tolerant plants are proven performers that thrive where others struggle.
Here are ten salt-tolerant trees, shrubs, perennials, and grasses that shine in salty conditions, whether by the coast or near salted roads.
-
Rugosa Rose (Rosa rugosa): These are rough and tumble 'Wild' Roses found for years in fields and probably in your grandma's garden. Featuring romantic blooms and excellent salt spray tolerance. Rugosa Roses are not called Salt Spray Roses or Beach Roses for nothing!
-
Oleander (Nerium oleander): Resilient flowering shrubs that thrive in salt air and even polluted city medians. Oeanders are so tough that they use them in the medians of the fourteen-lane freeways in Los Angeles. If they can stand salt air AND that much traffic abuse, you know they will perform well in your garden.
-
Pittosporum (Pittosporum tobira): Evergreen foundation shrubs that handle salt, wind, and heat with ease. They have that reputation because they are tough as nails!
-
Pacific Wax Myrtle (Myrica cerifera): Also called Bayberry, this fragrant evergreen makes a great hedge. These high-salt-tolerance plants work great as an evergreen hedge, with tiny flowers and a spicy fragrance.
-
Cotoneaster (Cotoneaster integerrimus): Salt-resistant groundcover with spring foliage and fall berries. With a distinctive 'structured-but-wild' look, this hard-working groundcover looks great all year.
-
Scarlet Bottlebrush (Callistemon spp.): Striking red, brush-like flowers and excellent salt tolerance for warmer regions.
-
Mugo Pine (Pinus mugo): Hardy, deer-resistant mounding conifer that handles roadside salt.
-
Daylily (Hemerocallis spp.): Perennial flowers that bloom in many colors and keep thriving in salty soils.
-
Fountain Grass (Pennisetum alopecuroides): Ornamental grass with graceful motion in salty winds.
- Bay Laurel (Laurus nobilis) - Evergreen Mediterranean tree with fragrant foliage that tolerates coastal salt spray and doubles as a culinary herb source.
