What Are the Sunlight Requirements for Mullein?
Mullein originates in sun-drenched, open landscapes. It thrives under full sun conditions, necessitating direct, intense light for at least 6 hours daily to ensure vigorous growth and optimal flowering. Proper lighting drives photosynthesis efficiently, promoting robust foliage and the plant’s characteristic tall, stately flower spikes. In varying environments, prioritize sunniest spots or leverage artificial grow lights to mimic natural conditions. Consistent light exposure influences mullein’s growth cycle and health, impacting its ornamental appeal and viability.
