What Are the Sunlight Requirements for Periwinkles?
Periwinkles thrive in warm climates, often found in their native Madagascar, where they are exposed to bright, tropical light. Optimal conditions for periwinkles include full sun to partial shade, necessitating at least 6 to 8 hours of high light intensity daily. Proper light exposure ensures efficient photosynthesis, leading to robust growth and prolific flowering. Importantly, direct sun encourages blooming, while too little light may result in leggy plants and fewer flowers. Indoors, placing periwinkles near a south-facing window or under grow lights can mimic ideal conditions. In settings with intense midday sun, light shading may prevent scorching.
