Marigold

*Tagetes*

How to know it

A low bushy plant with finely divided leaves and dense orange or yellow flowers. Strongly scented leaves, which is the point.

What it does

Used across the region in garlands, offerings and ceremonies. In gardens it is planted between vegetables because the root secretions suppress certain soil nematodes and the scent deters some insects. It is one of the few companion planting claims with real evidence behind it.

Safety

Safe. The smell is strong and some children dislike it.

Two things to do with children

Plant a row between vegetable beds and explain the job it is doing. A flower with a purpose changes how children see a garden.

Use the petals as a dye or in offerings, depending on what is culturally right where you are.
