As a horticulturist with a deep interest in the cultural and practical uses of plants, I can provide you with an informed perspective on the traditional beliefs and potential scientific backing regarding marigolds.

Marigolds, known scientifically as Tagetes, are often associated with folklore and traditional gardening practices. In many cultures, marigolds are believed to repel pests, particularly in the garden. This is particularly true for insects that can damage vegetables and other plants. The strong scent and certain chemical compounds found in marigolds are thought to be the reasons for this repellent effect.

However, it's important to note that while some gardeners swear by marigolds as a natural pest deterrent, scientific evidence for this is mixed. Some studies suggest that marigolds can deter certain pests, while others indicate that the effect is minimal or inconsistent.

In addition to their use as a potential pest deterrent, marigolds are also grown for their vibrant colors and as a companion plant to attract beneficial insects like bees and butterflies, which can aid in pollination.

In summary, while there is some traditional belief and limited scientific support for marigolds repelling certain pests, it's not a guaranteed method for pest control in gardens.
