Roystonea regia is a majestic tropical palm native to Cuba and the Caribbean. Seeds have immature embryos at fruit fall and display highly irregular germination patterns requiring patience and consistent warmth.
Before sowing
Remove fleshy fruit pulp and rinse seeds thoroughly in water. Wear gloves handling fruit as pulp contains irritating calcium oxalate crystals.
Sowing
What to expect
Tips
Cover container with clear plastic to maintain humidity. Keep soil moist but not waterlogged. Germination is highly irregular; first shoots may appear after weeks but many seeds germinate only after months. Research indicates seeds often take 5-8 months to sprout. Maintain bottom heat using a heat mat. Place horizontally or with tip pointing downward. Once seedlings appear with 2-3 true leaves, transplant carefully into individual pots with quality potting mix.
