Hurricanes can wreak havoc in your landscape, but they can also reveal what plants are the toughest and most resilient. It’s a great learning opportunity.
A few weeks ago, Hurricane Sally came along and brought about 10 feet of surge and waves across my landscape and completely covered everything except the tallest trees for about 18 hours. (Fortunately, our house is on stilts and we did not have intrusion into our main living areas.)
As expected, the trees, including Dahoon Holly and Sweetbay Magnolia, took a beating but stayed intact. With their dense fibrous root system, most of the clumping native grasses also stayed put.

The most surprising plant species that survived were about a dozen Stoke’s aster and 3 perennial milkweed. 4-5 inches of soil all around them was washed away, most of the roots were exposed, and the leaves were stripped or dead. The other perennials that had lived nearby were all washed away. To my surprise, within about 10 days after the storm, these two plant species started poking up new stems and leaves.
Here’s a list of some of the plants either in my yard or in the neighborhood that survived Hurricane Sally’s storm surge and may be suitable to add to your coastal landscape:
- Dahoon holly, Ilex cassine
- Muhly grass, Muhlenbergia capillaris
- Dwarf Fakahatchee grass, Tripsacum floridanum
- Perennial milkweed, Asclepias perennis
- Stoke’s aster, Stokesia laevis, specifically the cultivars ‘Mel’s Blue’ and ‘Divinity’
- Bottlebrush, Callistemon citrinus
- Gardenia, Gardenia jasminoides
- Bougainvillea, Bougainvillea spp.
- Flax Lily, Dianella tasmanica
- Crapemyrtle, Lagerstroemia spp.
- Cabbage palm, Sabal palmetto
- Canary Island date palm, Phoenix canariensis
- Sweetbay magnolia, Magnolia virginiana
- Augustinegrass, Stenotaphrum secundatum
- And, unfortunately, the rhizomes of the invasive torpedograss also survived.
