The Royal Palm Tree, scientific name Roystonea
oleracea, is native to Cuba and North America. Royal Palm
Trees are popular in many warm, coastal landscapes, particularly in southern Florida and parts of California.
There are 10 species of Royal palm around the world.
Growth Rate: Fast
Height: up to 100ft
Light Requirement: full sun to partial shade
Water Requirement: moderate
Cold Tolerance: down to 28F
They can be found in the Caribbean, Central and South American, Florida, Texas and California. The grace and
beauty of a Royal palm makes it a popular tree along the streets of many cities. Often they are used in the islands
of large parking lots or in medians along the highway. Nothing says “tropical” like the majestic Royal palm.
The Royal Palm can reach 50 to 100 feet high with a growth rate of around a foot each year. Fragrant, yellow flowers
bloom in the summer. Evergreen leaf-blades reaching 18 to 36 inches top a crown shaft that is long and green. Purple
to black half-inch fruits are showy but not edible. They thrive in gardening zones 10 and 11 but can handle short
periods of cold as low as 28 degrees. Royal palms are commonly seen in the landscapes of palm tree enthusiasts.
It is often considered a “must-have” tree for those who love different types of palm trees. Growing Royal Palm
This palm prefers full sun to partial shade. Soil can be clay, sand or loam; it doesn’t seem to be very picky in this regard.
The Royal palm prefers acidic to slightly alkaline soil, but be careful not to have too much alkalinity or the fronds may
come out frizzled. The Royal palm likes lots of water but it is moderately drought tolerant. This makes it a good tree
even if you live in a place that has watering restrictions. While it does love to be watered, it must be well drained.
Amazingly though, they not only tolerate, but seem to thrive in the poor soil and drainage of urban environments
where other trees tend to do poorly.
