20 Most Attractive Coastal Flowers 

While many of us enjoy a sea view, cultivating a healthy garden on the coast can be difficult. The sea air, while bracing and restorative, can be difficult for a number of plants. High in salt, sea air is naturally corrosive. This poses further problems for gardeners as does the high salt content of the soil. These difficulties mean that many plants, particularly ornamental flowers, can struggle to grow and flower when planted close to the sea.

While this may seem frustrating, luckily there are a number of plants that are ideally suited to planting in coastal conditions. As well as adding color, interest and fragrance many coastal flowers can also help to slow down soil erosion, which is a common problem in coastal areas.

Our list of coastal flowers aims to highlight the range of plants suitable for this sometimes tricky environment. Incorporating plants of all shapes, sizes and growth habits, here are 20 of the most attractive and versatile coastal flowers.

1 Rosemary

A popular member of the herb garden, Rosemary (Rosmarinus officinalis) is also one of the best coastal flowers. Easy to grow, this woody herb is hardier than softer herbs such as chives or parsley making it an ideal inclusion on our list of coastal flowers.

Originating in the Mediterranean, Rosemary is hardy enough to withstand prolonged exposure to sea air. The plants even thrive in this position, if also planted in full sun. While the plants do require regular watering, planting in well draining soil so that root rot can’t develop is more important. Rosemary is hardy in USDA Zone 9 and warmer.

Despite this it is still an ornamentally attractive specimen. Planting in a container or planter can help to control the spread of the root system.
