Taxonomic Information

Appearance

Ixora is a small to medium-sized shrub that can grow up to 6 feet tall and wide. Its leaves are glossy, dark green, and oval-shaped. The shrub produces clusters of small, tubular flowers that come in shades of red, orange, pink, and yellow. The flowers are arranged in dense, round clusters that can measure up to 5 inches in diameter. The shrub’s blooming period is all year round, but it produces the most flowers in spring and summer.

Care Guide

Ixora is a relatively low-maintenance shrub, but it does require some care to thrive. Here are some tips:

• Water: Ixora needs regular watering to keep the soil moist. Water it deeply once a week, or more often during hot, dry weather.
• Fertilization: Ixora needs to be fertilized regularly during the growing season to encourage blooming. Use a balanced fertilizer every two weeks.
• Soil: Ixora prefers well-draining, acidic soil. If your soil is alkaline, amend it with peat moss or sulfur to lower the pH.
• Sunlight: Ixora needs full sun to partial shade to thrive. It can tolerate some shade, but too much shade can reduce blooming.
• Hardiness Zones: Ixora is hardy in USDA zones 9-11. It can be grown as a houseplant in cooler climates.

Common Pests & Diseases

Ixora is generally resistant to pests and diseases, but it can be susceptible to the following:

• Scale: These insects can infest the shrub and suck the sap from its leaves, causing them to yellow and drop. Use an insecticidal soap to control the infestation.
• Spider mites: These tiny mites can cause the leaves to become speckled and stippled. Use an insecticidal soap to control the infestation.
• Root rot: This fungal disease can occur if the shrub is overwatered or planted in poorly draining soil. To prevent root rot, make sure the soil is well-draining and avoid overwatering.
