• Should be sown in a warm, humid environment
• Germination can take several weeks, depending on the conditions provided

Typical Issues

• Aphids, mealybugs, and spider mites
• Root rot can also be an issue
• Overwatered or the soil is not well-draining

Treatment Recommendations

• Pests can be controlled with insecticidal soap or neem oil
• To prevent root rot, ensure the plant is in well-draining soil and avoid excessive watering
• If root rot develops, remove affected roots and repot the plant in fresh soil

• Named for the distinctive purple spots on its leaves
• Spots add to the ornamental appeal of the plant
