Typically found growing in the understory of wooded areas or along the edges of forests, this deciduous shrub produces small, pinkish-purple flowers in the spring and summer, eventually giving way to clusters of bright, magenta-colored berries in the fall. These berries are a food source for birds, including northern bobwhites and bluebirds.
To make American beautyberry even more beautiful in your garden, consider planting it in groups or mass plantings to showcase its vibrant color. You also can mix it with other native plants, such as Florida anise, swamp milkweed, or goldenrod, to create a diverse and colorful landscape that attracts a variety of pollinators.
While American beautyberry is generally low-maintenance and disease-resistant, it may benefit from regular pruning to encourage a fuller and more attractive shape. If you want to keep the plant looking its best, trim back any dead or diseased branches in late winter or early spring before new growth begins.

This versatile perennial can be planted in various settings, from borders and rock gardens to trellises and fences. It also makes an excellent groundcover, spreading quickly and providing a lush, green carpet of foliage. But remember that it has an extreme flammability rating, so you shouldn’t plant it too close to your house.
To keep your coral honeysuckle looking its best, provide it with plenty of support, such as a trellis or fence. This will encourage it to climb and help prevent it from becoming too leggy or sprawling. To promote new growth and keep it from getting unruly, you also can prune it back in late winter or early spring.

How to Choose Native Plants for Your St. Augustine Landscape
St. Augustine is home to a diverse range of native plant species, from stunning wildflowers to lush shrubs and trees. With an average low temperature of around 48 degrees Fahrenheit, the city falls primarily into USDA hardiness zone 9a. This zone provides the perfect conditions for many native plants to thrive, but you must choose plants well-suited to your specific yard.
Not only do native plants enhance the beauty of your yard, but they also support the local ecosystem and help maintain the area’s natural balance. But while the region’s well-draining, sandy soil is ideal for many native plants, some may require additional nutrients or amendments to thrive.
Moreover, many native plants are drought-tolerant and can withstand hot, humid summers, but you must consider water usage and conservation. Using mulch and compost can help retain soil moisture and reduce the need for watering.
Before selecting plants, test your soil first. You can get help from your local cooperative extension or soil testing lab to determine your soil’s pH level, texture, and nutrient and salinity levels. This way, you can choose the plants best suited to your soil type.
FAQ About Native St. Augustine Plants
While St. Augustine is known for its lush greenery and subtropical climate, creating a backyard buffer can be an essential step in preserving the natural beauty of the area and protecting your home from hurricanes. Native plants are an excellent choice for this purpose, as they are well-suited to the local climate and can provide food and shelter for local wildlife.
Some of the best native plants for a backyard buffer in St. Augustine include coontie, firebush, muhly grass, red cedar, and wax myrtle.
Apart from beach sunflowers, other plants that bloom year-round in Florida include the Egyptian star cluster, plumbago, and porterweed. But remember that some perennial plants that show flowers all year in South Florida, like firespike, only bloom in certain months in North Florida.
The type of soil found in Northeast Florida can vary depending on location. But since St. Augustine is known for its warm weather, beautiful beaches, and diverse ecosystems, including salt marshes, barrier islands, and coastal forests, the city has mostly sandy soil with low fertility.
The sandy soil here is well-drained and doesn’t retain moisture well, making it challenging for plants to establish deep roots and absorb the nutrients they need to thrive. Adding organic matter, like compost, to sandy soil can help improve soil structure, water-holding capacity, and nutrient content. Still, it’s better to choose native plants well-suited to the local soil conditions as they don’t require excessive watering or fertilization.
Even though St. Augustinegrass is a popular choice for many homeowners in the area, it may not be the best fit for a garden that features a variety of native plants. This is because St. Augustine grass is known to be aggressive and can outcompete other plants for resources.
A better option would be Zoysiagrass. This warm-season grass can thrive in the heat and humidity of St. Augustine and has a slower growth rate than St. Augustinegrass. This means it’s less likely to compete with native plants for resources, allowing them to grow and flourish.
Another option to consider is a ground cover, such as coontie, beach sunflower, creeping phlox, dwarf mondo grass, or creeping thyme. These low-growing plants can provide a green carpet-like appearance without the aggressive growth of St. Augustinegrass. They’re also great for edging walkways or filling in gaps between stepping stones – providing a visual contrast and adding texture to your garden.
Where to Find Native Plants in St. Augustine
St. Augustine is blessed with a rich diversity of native plant species, including flowering perennials, shrubs, and trees that thrive in the area’s unique climate and soil. If you’re looking to add some indigenous flora to your garden, there are several local nurseries and plant resources to check out.
Start your search with the Florida Native Plant Society, a statewide organization that promotes using native plants in landscaping and conservation. Their website provides much information on local plant species, their growing conditions, and where to find them.
When selecting native plants for your garden, consider the environmental conditions of your site, including soil type, water availability, and exposure to sun and shade. Also, purchase plants from reputable sources and avoid transplanting them from the wild.
Adding native plants to your landscape can help create a sustainable and low-maintenance garden that supports local ecosystems and provides habitat for native wildlife.
But if you’re short on time or unsure where to start, consider hiring a St. Augustine landscaping pro to help design and maintain your beautiful, eco-friendly garden.
