Roystonea reagia - Cuban Royal Palm - 20 seeds

Plant Description

Name: Roystonea regia
Common Names: Cuban Royal Palm, Florida Royal Palm

Roystonea regia, commonly known as the Cuban Royal Palm, is a magnificent and stately palm tree native to the Caribbean, particularly Cuba, and parts of Central America. It is widely admired for its tall, smooth, light-gray trunk, which can reach heights of 20–30 meters (65–100 feet) and its lush, arching fronds that form a large, graceful canopy. The crownshaft (the green part just below the fronds) adds a touch of elegance to this majestic tree.

This palm is often planted as an ornamental feature in parks, avenues, and large gardens, giving a tropical, grand atmosphere. It produces small, white flowers and purple-black fruits that attract birds and wildlife.

Cultivation of Roystonea regia

Conditions:

1. Light: Roystonea regia thrives in full sun. It prefers a location with at least 6 hours of direct sunlight per day, although it can tolerate light shade when young.

2. Temperature: This palm is suitable for USDA zones 10-11 and prefers warm, tropical, or subtropical climates. It can tolerate brief periods of cold down to 30°F (-1°C), but it thrives in warmer conditions. Frost can damage or kill young palms.

3. Soil: Roystonea regia prefers well-draining, fertile soils but is adaptable to a range of soil types, including sandy, loamy, and even clay soils. Slightly acidic to neutral soil (pH 6.0-7.5) is ideal.

4. Water: This palm prefers consistently moist soil, especially when young. It is somewhat drought-tolerant once established, but regular watering will keep it healthy and thriving, particularly during dry spells.

Planting and Care:

1. Planting: Plant Roystonea regia in the spring or early summer in a location with full sun and plenty of space. Dig a hole twice the size of the root ball and backfill with well-draining soil. Water thoroughly after planting.

2. Fertilization: Fertilize the tree in spring and summer with a slow-release palm fertilizer that includes micronutrients such as manganese, magnesium, and potassium to encourage healthy growth and prevent nutrient deficiencies like frizzle top.

3. Pruning: Regularly remove dead or damaged fronds to maintain a neat appearance. Avoid excessive pruning, as this palm naturally sheds old fronds.

Propagation

1. Seeds: Roystonea regia is propagated by seeds. Collect the ripe seeds (when they turn black), clean off the pulp, and soak them in water for a few days to soften the seed coat. Plant them in a well-draining seed mix, keeping the soil warm and moist. Germination can take a few weeks to several months, depending on conditions.

2. Transplanting: Young palms can be transplanted when they outgrow their containers. Ensure the transplant site has ample space for the tree to grow to its full size.
