What Are the Sunlight Requirements for Canna lilies?
Canna lilies originates from tropical and subtropical regions, thriving in warm and humid conditions. The optimal lighting for canna lilies is full sun to partial shade, with a preference for bright, direct light for at least 6 to 8 hours a day. This light intensity boosts photosynthesis, encourages robust growth, and is crucial for vibrant blooms. Inadequate light may lead to leggy plants and poor flowering. For gardeners, placing canna lilies in a south-facing location ensures maximum light exposure. Indoors, use grow lights or position near a sunny window. In greenhouses, minimal shading is required to prevent scorching in peak summer months.
