A queen palm tree (Syagrus romanzoffiana) is what many think of when they imagine a palm tree. They grow 20 to 25 feet tall, and their glossy, green, 3-foot foliage droops down to form a canopy. In late summer to early winter, queen palm trees produce orange, date-like fruit that can attract undesirable insects. Queen palm trees are indigenous trees to South America and are hardy in USDA hardiness zones 9 to 11. Growing queen palm trees from seed requires a little diligence but can reward you with many queen palm seedlings.
Set your queen palm seeds into a bowl of water that is 70 to 75 degrees F. Let them soak for 48 hours. Replace the warm water in the bowl on the second day.
Mix 10 cups water and 1 cup household bleach into a large bowl or sink. Drop in the 4-inch plastic pots to sterilize them, letting them soak for 30 to 40 minutes. Rinse off each sterilized pot in hot water, and let the dry.
Place seed starting mix into the 4-inch plastic pots until each is about half full.
Pour water into each 4-inch plastic pot to thoroughly dampen the seed-starting mix.
Plant three queen palm seeds in each 4-inch plastic pot, gently pushing down on each. Cover your seeds with 1 inch of germinating medium.
Set your pots where the temperature stays between 65 and 75 degrees F and there is 8 to 10 hours of sunlight. Kept the soil moist at all times by misting the surface.
Transplant your queen palm trees seedlings when they have grown to about 4 inches in height.
