Ixora coccinea Maui Yellow / Flame Woods

Ixora coccinea 'Maui Yellow' Overview

Best Growing Environment

Ixora coccinea 'Maui Yellow' thrives in tropical and subtropical environments where temperatures remain consistently warm. This plant prefers well-drained, slightly acidic to neutral soils with a pH range of 5.0 to 6.5. Sandy loam soils enriched with organic matter provide ideal growing conditions. The environment should be humid, with regular rainfall or irrigation to keep the soil consistently moist but not waterlogged. Protection from strong winds is beneficial, as Ixora can be sensitive to drying out.

Common Names

• Maui Yellow Ixora
• Flame of the Woods
• Jungle Flame
• West Indian Jasmine

Average Height and Diameter

Ixora coccinea 'Maui Yellow' typically grows to an average height of 4 to 6 feet (1.2 to 1.8 meters) and can spread to a diameter of about 3 to 4 feet (0.9 to 1.2 meters). In optimal conditions, the plant can reach even greater heights and spread more widely.

Growth Rate

The growth rate of Ixora coccinea 'Maui Yellow' is moderate. Under ideal growing conditions, it can achieve significant growth within a few years, forming a dense and attractive shrub.

Sun Requirements

Full sun to partial shade is ideal for Ixora coccinea 'Maui Yellow'. It thrives with at least 6 hours of direct sunlight daily, which promotes abundant flowering and healthy foliage. In very hot climates, some afternoon shade can help prevent leaf scorching.

Cold Hardiness

Ixora coccinea 'Maui Yellow' is sensitive to cold and frost. It is best suited for USDA zones 9b to 11, where temperatures remain above 40°F (4°C). In cooler zones, it can be grown as a container plant and moved indoors during the winter months.

Water Requirements

Consistent moisture is essential for Ixora coccinea 'Maui Yellow'. The soil should be kept evenly moist but not waterlogged. Regular watering, particularly during dry spells, is crucial. Mulching around the base of the plant can help retain soil moisture and reduce the frequency of watering.

Detailed Fertilizing Guide

1. Early Spring: Apply a balanced, slow-release fertilizer, such as 10-10-10, at a rate of 1 to 2 pounds per 100 square feet. This supports new growth and flowering.
2. Mid-Summer: Apply a second dose of balanced fertilizer to maintain healthy growth and continued flowering. A foliar feed with a balanced liquid fertilizer can also be beneficial during this period.
3. Fall: Use a low-nitrogen fertilizer, such as 4-10-10, to prepare the plant for the cooler months and support root development.
4. Additional Nutrients: Ixora benefits from micronutrients like magnesium and iron. Applying Epsom salts (magnesium sulfate) at a rate of 1 tablespoon per gallon of water once a month can help maintain vibrant foliage. Iron chelate can be applied if yellowing leaves indicate iron deficiency.

Planting Guide

1. Site Selection: Choose a location with full sun to partial shade and well-drained soil.
2. Soil Preparation: Amend the soil with organic matter, such as compost or peat moss, to improve fertility and drainage.
3. Planting Time: The best time to plant Ixora is in the spring or early summer when temperatures are warm.
4. Planting Depth: Dig a hole twice as wide and the same depth as the root ball. Place the plant in the hole, ensuring the root crown is level with the soil surface.
5. Backfilling: Fill the hole with soil, gently tamping it down to eliminate air pockets. Water thoroughly after planting.
6. Mulching: Apply a 2 to 4-inch layer of mulch around the base of the plant to conserve moisture and suppress weeds.
7. Spacing: Space plants 3 to 4 feet apart to allow for adequate air circulation and growth.

USDA Zone

Ixora coccinea 'Maui Yellow' is best suited for USDA zones 9b to 11. In these zones, temperatures remain warm year-round, providing the ideal conditions for this tropical plant to thrive. In cooler regions, it can be grown in containers and brought indoors during the colder months to protect it from frost and low temperatures.
