What are the light requirements for Pride of India?
Pride of India requires bright, indirect light to thrive indoors. Insufficient light can lead to leggy growth, reduced flowering, and pale foliage. Place your plant near an east- or west-facing window where it can receive ample light without direct sun exposure. If you have a south-facing window, use sheer curtains to filter the sunlight. Rotate the plant regularly to ensure all sides receive adequate light. If natural light is limited, consider using a grow light to supplement its needs. A fluorescent or LED grow light positioned 12-18 inches above the plant can provide the necessary light for healthy growth and flowering.
