Have you ever looked at a succulent and thought, “This looks just like a piece of coral!”? If so, congratulations—you’ve just unlocked a fresh and creative way to style your plants with a touch of ocean magic.
An Under the Sea Succulents arrangement isn’t just beautiful—it’s downright fascinating. With their twisting forms, soft spines, and layered rosettes, succulents can mimic corals, sea anemones, and even tiny marine creatures. The best part? They don’t need saltwater or high-maintenance care!
Imagine having a little piece of the ocean right on your desk or windowsill. Sounds amazing, right? Let’s dive in and create your own succulent reef with Green Sedum!
1. Choose the perfect pot – the “ocean” for your under the sea succulents
Before picking your succulents, take a moment to think about the pot—because this will be the miniature “ocean” that brings your design to life. The right pot doesn’t just hold your plants; it sets the entire mood for your arrangement. So, choose wisely!
Color – capture the essence of the sea
Opt for shades that evoke the ocean, like deep blue, aqua, seafoam green, or sandy white. Pots with wave-like textures, stone patterns, or a crackled glaze can mimic the water’s surface beautifully. And if you’re lucky enough to find one with coral fossil patterns? Congratulations—you’re already halfway to achieving that perfect Under the Sea vibe!
Shape – gentle waves or coral reef?
- Round or oval pots: These create a pond-like feel, perfect for a calm, minimalist look.

- Long or rectangular pots: Ideal for a stretched-out reef effect, allowing you to showcase multiple succulents together.

- Shell, starfish, or conch-shaped pots: A unique statement piece that instantly highlights the ocean theme!

What if you can’t find the perfect pot?
No worries! You can easily transform a plain pot into an oceanic masterpiece with a little creativity:
- Paint an ombré blue gradient to mimic the ocean’s depth.
- Sprinkle a fine layer of sand on the surface for a natural, beachy feel.
- Use decals or hand-paint waves and coral designs for an artistic touch.
Now that you have the perfect “ocean,” it’s time to find the succulent reefs that will complete your design!
2. Choose the perfect succulents – the “residents” of your landlocked ocean
Now comes the fun part—choosing the plants! A successful Under the Sea Succulents arrangement isn’t just about beauty; it’s about textures, colors, and shapes that evoke the wonders of the ocean. Think of it as crafting your own miniature coral reef, complete with vibrant corals, flowing anemones, and unique sea creatures.
Coral-inspired succulents – branching beauties of the reef
These succulents have intricate, branching structures or wavy forms that resemble real coral:
- Euphorbia tirucalli ‘Firesticks’ – Slender, fiery-orange branches that look just like fire coral.
- Crassula ovata ‘Gollum’ – Glossy, tubular green leaves that mimic delicate sea anemone tentacles.
- Euphorbia lactea variegata ‘Bones’ – White-green crested branches that resemble fossilized coral.


Anemone-like succulents – soft blooms of the deep
Sea anemones are known for their soft, flowing shapes, and these succulents bring the same look to your arrangement:
- Echeveria ‘Neon Breakers’ – Wavy purple edges that give the illusion of a blooming sea anemone.
- Sempervivum calcareum – Grows in tight, circular clusters, just like a bed of anemones clinging to rocks.
- Faucaria tigrina (Tiger’s Jaw) – Tiny serrated leaves that look like an open clamshell. Don’t worry, it won’t bite!

Starfish & seashell succulents – quirky shapes for ocean vibes
These unique plants add an extra touch of underwater magic:
- Haworthia cooperi – Translucent, jelly-like leaves that resemble glowing sea creatures.
- Gasteria ‘Little Warty’ – Slightly bumpy leaves that could easily be mistaken for a tiny starfish.
- Opuntia Hybrid Crest ‘Roller Coaster’ – Wavy, rippling pads that look like flowing seaweed.
Color tips for an eye-catching design
- For a vibrant coral reef look, mix in warm tones like orange, red, and pink.
- To create a deep-sea mystery, combine blues, purples, and silvery whites.
- For a true-to-life reef effect, don’t be afraid to mix and match different colors to create depth and diversity.
Now that your succulents are ready, it’s time to arrange them and bring your miniature ocean to life!
3. How to arrange your plants for the perfect “under the sea” look
Now that you’ve chosen the perfect “sea creatures” for your Under the Sea Succulents arrangement, it’s time to bring them to life! The key to a stunning display is arranging them in a way that looks natural and dynamic—just like a real coral reef. Imagine yourself diving deep into the ocean, observing how corals, anemones, and marine life settle into their own unique spots, yet all come together in perfect harmony.
Step 1: Start with a focal point
Choose a tall, eye-catching succulent to be the main anchor of your arrangement. This could be Euphorbia tirucalli ‘Firesticks’ with its striking fiery hues or Euphorbia lactea variegata ‘Bones’ with its pale, coral-like branches. These plants will serve as the towering coral structures in your miniature underwater world.
Step 2: Fill in with medium-sized plants
Next, arrange smaller, more spreading succulents like Echeveria ‘Neon Breakers’ or Sempervivum calcareum around the focal plant. This helps soften the composition and mimics the way sea anemones and other reef dwellers spread naturally along the ocean floor.
Step 3: Add trailing plants along the edges
To create the effect of movement, place trailing or low-growing succulents like Haworthia cooperi or Opuntia Hybrid Crest ‘Roller Coaster’ near the edges of your planter. These plants give the illusion of swaying seaweed or tiny marine creatures nestled among the rocks.
Step 4: Finish with decorative sand and stones
Finally, add a layer of sand-colored pebbles, tiny seashells, or decorative stones to enhance the oceanic feel. For an extra magical touch, place a small blue stone or glass bead to reflect light, creating a sparkling “bubble” effect—just like sunlight dancing on the ocean waves.
And that’s it! You’ve just created your very own miniature coral reef, perfect for a desk, shelf, or windowsill. Now all that’s left to do is find the perfect spot and enjoy your little slice of the ocean!
4. Caring for your “dry ocean”
Unlike an actual coral reef, your Under the Sea Succulents arrangement requires a special care routine to maintain its natural beauty with minimal effort. The good news? These “ocean dwellers” are incredibly low-maintenance. Just meet their basic needs, and you’ll have a thriving miniature seascape all year round.
Light – the “tropical sun” for your arrangement
Succulents in this setup love bright light, especially morning sun or strong indirect light. If you’re keeping them indoors, place them near a south- or west-facing window for the best exposure. If your space lacks natural light, consider using a grow light to keep them happy.
Watering – don’t “drown” them!
Since this is a dry ocean, too much water can sink your coral reef. Water sparingly—about once every two weeks—making sure the soil is completely dry before the next watering. When watering, avoid getting water on the leaves, as this can lead to rot or mold.
Soil – don’t let your “coral” sink in the mud
To keep your succulents thriving, use a well-draining soil mix. A simple formula is succulent potting soil mixed with pumice or perlite. This helps prevent water retention in the roots and mimics their natural arid environment.
Fertilizer – a little boost goes a long way
Succulents don’t need frequent feeding, but a light dose of fertilizer every two months will enhance their color and growth. Use a diluted, succulent-friendly fertilizer to avoid overstimulating growth, which can alter their natural shape.
Bring your ocean scene to life with creative touches
Want to make your arrangement even more eye-catching? Try adding a few decorative elements!
- Seashells: Scatter a few small shells to create an authentic seabed effect.
- Mini plastic fish: A tiny fish peeking out from your coral reef (no feeding required—promise!).
- Blue gravel or glass pebbles: A layer of ocean-colored stones or shimmering glass pieces will enhance the illusion of water glistening in the light.
With just a few simple steps, you’ve created a stunning underwater-inspired succulent arrangement—low-maintenance, unique, and the perfect piece of ocean magic for your home. Now, sit back, admire your Under the Sea Succulents, and enjoy the serene beauty it brings!
5. Bring the ocean home!
An Under the Sea Succulents arrangement isn’t just a beautiful decorative piece—it also brings a sense of calm, as if you’re diving into a vibrant coral reef. Easy to care for, long-lasting, and always lush, this miniature ocean scene will add a refreshing touch to your space.
