Coco de Mer – What makes this palm so special?

If you’ve ever seen a giant seed that looks like a heart, you’ve probably spotted a Coco de Mer. It’s not just any plant – it’s the national symbol of the Seychelles and one of the world’s most recognizable seeds. The palm grows on a few remote islands, and its massive, double‑lobed nut can weigh up to 30 kg. People love it for the dramatic look, the story behind it, and the fact that it’s super rare.

What is the Coco de Mer?

The Coco de Mer (Lodoicea maldivica) is a solitary palm that lives for centuries. It only produces one seed per year, and that seed takes up to three years to mature. The seed’s shape has inspired myths about love and fertility for generations. In the wild, the palm reaches about 25 m tall, but most indoor growers keep a smaller variety that stays under 3 m.

Because the palm grows in salty, sandy soil, it’s adapted to tough conditions. Its roots spread wide to find water, and the leaves are thick and waxy to keep moisture in. These traits let it survive on small islands where other plants would struggle.

How to grow and care for your Coco de Mer

Getting a Coco de Mer at home is a commitment, but it’s not impossible. Here’s a quick checklist:

• Light: Give it bright, indirect sunlight. A sunny windowsill works, but avoid harsh midday rays that can scorch the leaves.
• Soil: Use a well‑draining mix with sand, peat, and perlite. The palm hates soggy roots.
• Water: Keep the soil slightly moist, but let the top inch dry out between watering. Over‑watering is the #1 mistake.
• Humidity: It prefers moderate humidity. A simple pebble tray or occasional misting helps in dry homes.
• Fertilizer: Feed with a balanced liquid fertilizer every month during the growing season (spring‑fall). Cut back in winter.

Patience is key. It can take years before the plant shows noticeable growth, and the iconic seed may never appear indoors. Still, the striking fronds make a bold statement in any room.

If you ever spot a Coco de Mer seed in the wild, remember it’s protected by law. The Seychelles government bans export to keep the species safe. That’s why most plants you find in nurseries are grown from cuttings, not harvested seeds.

Whether you’re a seasoned collector or just curious about tropical plants, the Coco de Mer offers a blend of beauty and intrigue. Its massive seed, unusual shape, and long history make it a conversation starter. With the right light, soil, and a bit of patience, you can enjoy a slice of island magic right at home.
