The Biography of Calendula
How did the medic's wound flower become a throwaway bedding plant?
PAST
Calendula was a working medicine for centuries, used on the skin for wounds, burns, and sores. Monks grew it in physic gardens, and the name officinalis marks it as a plant of the apothecary's store.
It went to war in living memory. Field medics in the First World War carried tinctures of its petals to dress wounds in the trenches, which is how it earned the name the marigold of the trenches.
PRESENT
Now it is mostly a cheap tray of orange bedding plants at the garden centre, grown for colour and pulled out at the end of the season. The salve survives in a few natural skin creams, but the link between the cream and the flower in the bed is mostly lost.
Gardeners who know companion planting still use it among the vegetables. For most people it is just a marigold, and not even the most fashionable one.
FUTURE— you are here
The flower keeps doing all of it at once. It heals skin, colours food, traps pests off the crops, feeds the bees, and reseeds itself for next year. Few plants pay back a packet of seed so many ways.
