The sago palm (Cycas revoluta), also known as the king sago, sago cycad, or Japanese sago palm, is a striking ornamental plant that closely resembles a palm tree but is actually a cycad. Native to southern Japan, including the Ryukyu Islands, as well as parts of China, this ancient plant belongs to the gymnosperm family Cycadaceae. It features long, stiff, glossy green fronds that arch gracefully from a central trunk, which is often covered with brown, hair-like fibers, giving it a rugged, textured appearance.
Sago palms are evergreen and remarkably slow-growing, taking up to 50 years to reach their mature height of approximately 12 feet (3.5 meters). Rather than flowering or producing fruit, the plant develops large, cone-like structures containing seeds. Its distinctive rosette of shiny, pinnate leaves and its ability to thrive both indoors as a houseplant and outdoors in warm climates make it a popular choice for gardeners and plant enthusiasts. With its tropical aesthetic and enduring resilience, the sago palm adds a touch of elegance to any indoor or outdoor space.

Why will I love it?
The Sago Palm (Cycas revoluta) is a showstopper with its feathery, arching fronds and bold, structured appearance. It’s one of the oldest plant species on Earth, giving your home a prehistoric vibe. Its slow growth and low-maintenance nature make it a fantastic addition to any indoor space.
Light or shade?
The Sago Palm thrives in bright, indirect light but can tolerate some direct sunlight. If you’re placing it indoors, aim for a spot near a sunny window that gets about 4-6 hours of filtered light daily. Avoid low-light areas, as this can stunt its growth.
Where should I put it?
This plant is perfect for living rooms, offices, or entryways, where its dramatic foliage can be admired. Its compact size makes it manageable for tabletops or larger pots on the floor. Just keep it out of high-traffic areas to avoid brushing against the sharp fronds.
How do I keep it alive?
The key to keeping a Sago Palm happy is proper watering and well-draining soil. Let the top inch of soil dry out between waterings to avoid root rot. In winter, reduce watering even more as the plant goes semi-dormant. Use a pot with drainage holes and a sandy, slightly acidic potting mix. It prefers a temperature range of 60-85°F and doesn’t need high humidity, so avoid misting. Feed it a slow-release fertilizer designed for palms during the growing season (spring and summer).
Did you know?
The Sago Palm isn’t just a survivor from the age of dinosaurs—it’s also incredibly hardy. Despite its longevity, all parts of the plant are toxic if ingested, so keep it away from curious pets and children. Patience is required with this plant, as it grows slowly, but its timeless beauty is well worth the wait!
WARNING: Highly toxic for children and pets
The Sago Palm is highly toxic to both children and pets, particularly cats and dogs. All parts of the plant contain toxic compounds, but the seeds (nuts) are the most poisonous. The primary toxin, cycasin, can cause severe liver failure and other serious health issues if ingested.
If consumed, symptoms may appear within a few hours and can include:
- In Pets (Dogs & Cats): Vomiting, diarrhea, drooling, lethargy, loss of appetite, seizures, jaundice, and liver failure.
- In Humans (Children & Adults): Nausea, vomiting, diarrhea, dizziness, and potential liver damage in severe cases.
Even a small amount of ingestion—especially of the seeds—can be fatal, particularly in dogs. If you suspect poisoning, immediate veterinary or medical attention is necessary. Due to its toxicity, households with pets or young children should avoid keeping sago palms or ensure they are placed well out of reach.
