The Winged everlasting daisy requires full sun, which means it needs above 6 hours of sunlight daily to thrive. It's crucial to observe how sunlight moves through your garden and select locations that provide a perfect balance of light and shade. This ensures the plants receive the adequate sunlight they need for healthy growth, enhanced flowering, and leaf production. Originating from open habitats, these plants have evolved under constant solar exposure, making intense light pivotal for their development.

When natural sunlight is inadequate, especially during winter or in less sunny spaces, artificial lighting becomes essential for the growth of indoor Winged everlasting daisies. LED lights, which can be customized to provide specific wavelengths needed by the plants, are a popular choice. For optimal growth, full sun plants require 30-50W/sq ft of artificial light, partial sun plants need 20-30W/sq ft, and full shade plants require 10-20W/sq ft. The light source should be positioned 12-36 inches above the plant to mimic natural sunlight. Additionally, to emulate the natural daylight duration, most plants need 8-12 hours of light per day.

When cultivated indoors with inadequate light, Winged everlasting daisies may exhibit several symptoms. Small and sparser leaves can indicate that new growth is not receiving enough light, making plants look weak and stretched-out. The plant may drop older leaves early to conserve resources, leading to slower or halted growth and paler new leaves. This signals a lack of chlorophyll and essential nutrients, which is detrimental to the plant's health.

Excessive sunlight can harm Winged everlasting daisies, causing symptoms like chlorosis, where leaves turn yellow due to chlorophyll breakdown, impairing photosynthesis. Sunscald damages leaves or stems with intense exposure, presenting as bleached areas. Other signs include leaf curling, a defense mechanism to minimize sun exposure and water loss, wilting from increased transpiration, and leaf scorching evidenced by brown, crispy leaf edges. These symptoms suggest the plant is receiving more sunlight than it can handle, affecting its overall health.

For optimal growth, gradually moving the plants to sunnier locations can help, aiming for at least 6 hours of direct sunlight daily. Using a south-facing window and keeping curtains open during the day can maximize sunlight exposure. If moving the plant is not feasible, consider artificial lighting, keeping lamps on for at least 8 hours daily or investing in grow lights. For outdoor plants, it's crucial to adjust their location gradually to prevent sunburn. Pruning trees to minimize shade and transplanting to sunnier locations during the dormant period can also enhance sunlight exposure. Note that parts of the plant already affected by light issues may not recover, but new growth will be healthy with better light conditions.
