Do Daylily Need Full Sun?

Given the name daylily, one would assume that these flowers can only survive in direct sunlight. While daylilies thrive in full sun, they are also one of the most popular shade plants because they can tolerate partial shade. Unlike many other perennials, the daylily is a low-maintenance perennial thrives in a wide range of conditions, including poor soil and drought. Daylilies come in a variety of colors, shapes, and sizes. Daylilies can bloom from late spring through the first frost of fall by combining early, mid-season, late-blooming, and repeat blooming daylilies in a single plant.

What Will Happen If Daylily Does Not Get Enough Sun?

Daylilies need at least six hours of direct sun per day to thrive, but if they do not receive enough sun, they may begin to decline in health. Daylilies are photosynthetic and need sunlight to produce chloroplasts, the organelles that allow them to convert sunlight into energy. When the chloroplasts are not functioning properly, the plant will not synthesize nutrients and will eventually die.

If you notice that your daylilies are not thriving, it is important to give them more sun. You can transfer them to a brighter spot in your garden, or you can provide them supplemental light using a green lightbulb or fluorescent light. If you notice any wilting or yellowing, it is also a sign that your daylilies are not getting enough sun exposure and should be moved to a brighter location.

Can Daylily Survive Shade?

They can do well in slightly shady areas. However, they may produce fewer flowers. If they stayed longer in the full shade, they might be experienced wilting. Daylilies should not be planted under trees because the shade will stunt their growth, and the tree roots will obstruct the lilies’ extensive root system.
