Creating a radiation garden in outdoor plant boxes is a smart way to combine aesthetics with practical protection. Certain plants are known for their ability to absorb or mitigate radiation, making them ideal for such gardens. Sunflowers, for instance, are renowned for their phytoremediation properties, effectively absorbing radioactive contaminants from the soil. Other excellent choices include mustard greens, which thrive in outdoor boxes and are efficient at extracting heavy metals and radiation.

Ferns, particularly the Boston fern, are another great option due to their air-purifying abilities and resilience. Aloe vera, often grown in plant boxes, not only soothes skin but also helps neutralize harmful environmental toxins. For taller structures, consider bamboo, which grows quickly and provides dense foliage to block radiation.

When designing your radiation garden, ensure proper spacing and soil quality to maximize plant health. Regular maintenance, such as watering and pruning, will keep your outdoor plant boxes thriving. By selecting the right plants, you can create a beautiful and functional space that offers added protection against radiation.
