What Are the Sunlight Requirements for Rhaponticum?
Rhaponticum thrives in full sunlight but can tolerate partial shade. It requires at least 6 hours of direct sun daily, with light that leans towards the blue spectrum, promoting robust growth and bloom. Avoid low light conditions or prolonged shade, as this leads to weak, leggy growth. For indoor scenarios, use grow lights mimicking natural sunlight. Adapt lighting during growth cycles with longer light periods in vegetative stages.
