The King Alexander Palm (Archontophoenix alexandrae), also called the King Palm or Alexandra Palm, is a tall, fast-growing feather palm from the rainforests of Queensland, Australia. A smooth, ringed trunk with a flared base carries a bright green crownshaft and a full crown of long, arching fronds — a stately tropical look that works as a single specimen or planted in groups.

King Alexander Palm Breakdown
Appearance:
Straight, light gray trunk marked with rings and swollen at the base, topped by a smooth green crownshaft.
Fronds reach 6–10 feet long, with leaflets that are green on top and silvery underneath. Mature palms carry sprays of creamy white flowers below the crownshaft, followed by bright red fruit.
Growth Rate:
Fast.
With steady water and fertilizer it can add 1–2 feet or more of height a year.
Size:
Typically 30–40 feet tall in South Florida landscapes, taller with age, with a 10–15 foot crown.
Available in 25-gallon (7–8 ft) and 45-gallon (10–11 ft), as a single, double or triple. Doubles and triples are two or three palms grown together in one pot.
Sunlight Requirements:
Full sun to partial shade.
Young palms handle some shade; established palms do best in sun.
Water Needs:
Moderate to high.
It likes consistently moist soil and does not like to dry out — water regularly, especially through the dry season.
Soil Preferences:
Adaptable to sand, loam and clay as long as it stays moist; best in rich, well-draining soil.
Mulch to hold moisture in sandy yards.
Maintenance:
Low.
Self-cleaning crownshaft — old fronds drop on their own, so no ladder pruning. Feed with palm fertilizer 2–3 times a year.
Landscape Use:
Specimen or focal-point palm, driveway and property-line rows, poolside and courtyard plantings, and groups of two or three for a fuller canopy.
Best with some wind protection, since strong winds can tatter the fronds.
Climate Tolerance:
USDA zones 10a–11.
Protect from frost; a hard cold snap can burn the fronds. Low salt tolerance, so not the pick for direct oceanfront.
Need something slimmer for a tight spot? The Alexander Palm (Ptychosperma elegans) is a different, smaller palm. King Alexander is the bigger, faster one — the choice when you want height and a full tropical crown quickly.

Frequently Asked Questions
How to Plant & Care for King Alexander Palm in Florida
Choose Sun + Clearance
Palms prefer full to partial sun. Allow room for frond spread and future trunk growth.
Plant Slightly High
Dig a wide hole and plant with the root ball level to slightly above grade. Palms do not like being buried.
Backfill + Water In
Backfill with native soil and water thoroughly to settle. Avoid compacting too aggressively.
Consistent Watering (Critical)
Water deeply and consistently during the first few weeks. Most palm issues come from under-watering early on.
Fertilizer + Pruning
Remove only fully brown fronds. Apply a slow-release palm fertilizer after the palm has settled in.

What Florida Customers Say
I was searching for a better plant source and after checking the internet, the consensus by most locals was to check out Dino's Palms. I have ordered multiple times and every plant I have gotten has been above expectations with health and fullness. The customer service is excellent! I am kind of blown away at how great this company is and will continue to use this as my main plant connection.
My experiences with Dinos have been wonderful. The communication about my orders & delivery was spot on, the deliveries guys quick, efficient and friendly - they even cleaned up fallen leaves from the driveway. But its the product that shined the most. Healthy, lush, vibrant. The same size posts as local nurseries - but the plants themselves were larger, fuller and more robust than anywhere we shopped. I cant say enough great things about their operations, their services and their products.
I bought 12 plants. All in excellent condition. Good size. Delivery was on time. Thank you. I recommend it.
