Finding shrubs that thrive in shade can be a bit of a challenge compared to selecting plants for full sun, but it is manageable if you understand the light conditions. Plant descriptions often use terms like “full shade” or “part shade,” and it’s important to know what these terms really mean when determining the amount of sunlight the plants will receive. Generally, part shade or part sun refers to about 4 to 6 hours of bright sunlight daily, or receiving filtered light throughout the day, which is common under an open tree canopy. Full shade, on the other hand, is defined as fewer than four hours of sunlight daily.
In regions with intense heat, particularly during midday, the quality and timing of sunlight exposure can also affect plant health. If an area gets sunlight during the hottest part of the day, it is best to treat it like a full sun spot, even if it technically falls within the “part shade” category. This consideration helps ensure the plants selected for such spots can handle higher sun intensity.
While many shrubs can adapt to shade conditions, they often need at least some sunlight to thrive. Shade-tolerant varieties typically have a more open and airy form, and if they are flowering plants, they tend to produce fewer blooms in low light conditions. It is always a good idea to monitor how much sunlight a particular area receives by observing it over a few days and considering how long it remains comfortable to sit in. A spot that stays cool most of the day is likely full shade, while one that remains comfortable only for part of the day indicates a part sun/part shade location.
Azaleas are a beloved choice in the South due to their heat tolerance and vibrant blooms in a wide range of colors. Many newer varieties can rebloom in both spring and fall. Fothergilla, another excellent shrub for shady gardens, features fragrant white flowers in the spring and colorful fall foliage, with some types reaching up to 10 feet in height, while dwarf varieties are suitable for smaller spaces. Viburnum is another option, with several species that can tolerate part shade conditions and offer low-maintenance care. Finally, Mahonia is a lesser-known but fantastic shade-loving shrub. Its evergreen foliage and cheerful yellow flowers in late winter or early spring make it a standout addition to a shade garden. Newer hybrids also offer more colorful foliage for added interest throughout the year.
