23 de oktober de 2023

Speckle your coastal sightlines in a sea of colorful perennials, which resist deer, tolerate wind and salt spray, and can withstand the gusty breezes from the ocean’s tides. Ideal for exposed coastal gardens, certain flower varieties are more adaptable to the rugged conditions often found near the seaside. Between the dry heat, salty air, and sandy soil, these plants need well-draining soil and a sunny location to thrive. Read on for our favorite seaside plants to brighten your coastal garden.

African Lily

This vibrant flower adds an unexpected touch of the tropics to Northern gardens. When winter arrives, pots can be tended as houseplants indoors in a sunny spot. Blooms take shape in globes comprised of smaller star-shaped flowers.



Allium includes purple and sky-blue varieties, as well as chives. Because their scent is oniony rather than floral, they repel animals. Good drainage is essential.

Anise Hyssop

Anise Hyssop

This flower attracts butterflies with its licorice scent and violet hue. The three to five-foot-tall, drought-tolerant trouper thrives in full sun or partial shade. Also, plant it in an area with well-drained soil.

Bleeding Heart

Bleeding Heart

Belying its delicate appearance, Bleeding Heart holds up well in winter. You can cut the plants back midsummer after the foliage fades. Bleeding Heart prefers sunlight to partial shade.

Flowering Tobacco

Flowering Tobacco

Technically a tender perennial, Flowering tobacco can be grown almost anywhere as an annual. It lends grace and fragrance to beds and borders all summer. Flowering tobacco prefers warm weather and soil instead of cold, wet soil, which can cause root rot or other diseases.



Snip off blossoms before they mature to keep this prolific self-sower in check. Afternoon shade will help prevent leaf scorch. Despite prefering shade in warmer regions, the lady’s mantle can tolerate full sun.

Annual Poppies

Annual Poppies

Poppies reliably self-sow wherever the sun is ample, and the drainage is good. Seeds dormant in the soil can re-emerge unexpectedly years later. Plus, poppies are hardy flowers attracting butterflies and bees while producing vibrant colors in your garden.

Russian Sage

Russian Sage

Russian Sage stands tall—up to four feet. The lilac-blue sun worshipper, neither Russian nor sage but instead a Himalayan mint, yields four months of flowering. Russian Sage is suitable for coastal gardens because it tolerates alkaline soil.

Veronica «Sunny Border Blue»


If deadheaded faithfully, these flowers will bloom from May through October. This plant grows best in well-drained soil and full sun and forms in bushy clumps. Divide it every three years and share the wealth with friends.

Ornamental Grasses

Perfect for those summer salads. Sea kale, also known as sea cabbage, returns in the spring and thrives in a salty, seaside environment. This plant grows in more soil conditions, but well-drained to moist soil is best.



Yarrow is a beautiful plant for seaside gardens because the oversized tops help the delicate stems to sway in the coastal winds. The sturdy flower is available in several colors, including yellow, red, pink, orange, and white. Plus, yarrow is usually pest-free.

Sea Oats

Sea Oats

Sea oats are an excellent plant for ground covering as it spreads quickly. This ornamental grass will thrive in shady areas and is drought tolerant. Enjoy this plant into the fall as the foliage turns bronze.


Blanket Flower

Known as the blanket flower, the Gaillardia has a long bloom season that lasts from the beginning of summer until the first frost. The Gaillardia is also known to attract butterflies, increasing its beauty factor.


Creeping juniper ground cover

Great for ground cover, creeping juniper will spread quickly, filling your garden with lush greenery. Juniper thrives in full sun to part shade and well-drained soil but can also tolerate drought conditions. Blue, green, and gold foliage are also available color varieties.

Spring Garden Flowers:

In frost-free climates, the colorful cuphea blooms as a perennial. Thriving in full sun and well-drained soil, this perfect coastal flower can withstand harsh winds, salty soil, and dry heat. Plant and enjoy the range of vibrant blooms.


blue hydrangeas

Perennial Geraniums

Geraniums thrive in sunny environments. This flower has color varieties ranging from soft pink to deep purple. Usually grown as annual flowers, these plants can self-seed in milder regions or covered gardens.
