Ixora coccinea

Edward F. Gilman


Four to six-inch globular clusters of bright red, orange, yellow, pink, or white tube-shaped flowers bloom continuously under ideal conditions in full sun (Figure 1). The two to three inch-long leaves are bronzy when young, later turning to a glistening dark green. The much-branched, compact habit of Ixora makes it ideal for hedges, borders, screens, or as a specimen planting, and it may be pruned at any time. Shearing to maintain a hedge will reduce the flower display.

Use and Management

Ixora thrives in full sun in moist but well-drained acid soil but can tolerate some shade. Foliage turns yellow in alkaline soil such as next to sidewalks and foundations, where it is often planted. A continued micronutrient fertility program is neededto maintain green leaf color in alkaline soil. The cultivar 'Fraseri' has brilliant reddish-salmon flowers. 'Crimson King' has bright red flowers. Dwarf cultivars are available and are well suited for container planting.

Propagation is by cuttings.

Problems include nematodes, aphids, bagworms and scale.Chlorosis in alkaline soil makes this a high maintenance plant in many coastal landscapes. Treatment with an appropriate micronutrient fertilizer can temporarily prevent or correct chlorosis. Chelates with iron and/or manganese correct and help prevent chlorosis.

Pest and Diseases

Mushroom root rot can be a problem for Ixora.
