Part-Sun Plants

Definition and Light Preferences of Partial Sun Plants

Full-sun plants require 6+ hours of direct light. Full-shade species need 2 hours max. Part-sun plants sit between these two extremes — they typically require 4-6 hours of sunlight daily. For example, full-sun lavender will deteriorate quickly with just 4 hours of light, while part-sun hydrangea will thrive in such lighting conditions. 

The partial-sun type, however, shouldn’t be confused with partial-shade species. The terms are often used interchangeably, but there’s a significant difference between the categories. Part-sun leans toward more sun and can tolerate light closer to 6 hours. Part-shade leans toward more shade and can only tolerate slightly more than 4 hours of direct light. 

From Garden Edibles to Houseplants: Diversity & Use Cases Explained 

The category includes thousands of species. These are flowering ornamentals (e.g., Eyelash begonia, New Guinea Impatiens), foliage plants (e.g., Rock Hosta, Heart of Jesus), succulents (e.g., Snake plant, Leafy haworthia), and herbs (e.g., parsley). Many part-sun species can also be found among vegetables and fruits (e.g., Butterhead lettuce, Buffalo spinach, Beach strawberry, West Indian raspberry), as well as among trees, shrubs, and climbing plants. 

These plants thrive in different spaces. East-facing positions with morning sun and afternoon shade are considered the most favorable for the category. West-facing positions have the reverse pattern and better suit species that can tolerate more intense afternoon light (e.g., Bee balm, European blackberry). Also, many of them thrive under deciduous trees, near walls and fences, or in covered patios and porches.
