What it says
The marigold speaks of both grief and protection. The two senses have coexisted for a long time without contradiction: it is planted on graves in India and Mexico, and put into ointments almost everywhere else.
Its French name comes not from worry but from the Latin solsequier, "that follows the sun": the flower opens in the morning and closes at dusk.
Calendula
Calendula officinalis — pot marigold — is among the best-established medicinal plants for skin use. Its infused oils and ointments are used for irritation, chapping and dry skin.
The recognition is official: several European pharmacopoeias list it for topical use. That is rare for an ordinary garden flower.
Not to be confused with tagetes, the French or African marigold, often sold under the same common name. It does not share the same properties, and its scent is entirely different.
In the garden
It self-seeds, tolerates poor soil, flowers from May until frost, and attracts pollinators in quantity. The petals are edible — they colour rice or broth deep yellow, which earned it the name "poor man's saffron", without any of the taste.
our piece on flower symbolism places the marigold among the flowers of care and memory.
