Beltane (Bealtaine)

The start of summer in Ireland: a decorated hawthorn bush at the door, rowan on the cow’s tail.

At Bealtaine, the start of summer in the Celtic calendar, a “May bush”, usually a hawthorn, was set up in front of the house in Ireland and decorated with ribbons, painted eggshells or candles. On May Eve yellow flowers such as buttercups were gathered and placed around the house, in the belief that fairies could not pass them. Rowan was tied to cows’ tails against the evil eye, and herbs picked before sunrise on May morning were thought to be stronger. Cattle were driven between the fires lit on May Eve [1]. In folk belief a lone hawthorn belongs to the fairies, and harming it brings bad luck [2].

To prepare: Hawthorns flower in these weeks. Hawthorn can interact with heart medicines.

Kupala and Midsummer night

The night in Eastern Europe when herbs are believed to be most healing: wreaths are woven and St John’s wort is gathered.

In Eastern Europe, herbs and flowers gathered on the night of the summer solstice are believed to gain special healing power. On Kupala night in Belarus, girls weave wreaths of wild flowers and float them on the river; whoever finds the fern flower, said to bloom once a year, is believed to see the future and understand the language of plants [1]. At the Latvian festival of Jāņi, women weave wreaths of daisies, clover and buttercups and men wear crowns of oak leaves; because herbs are thought to be most potent at the solstice, yarrow, mint and St John’s wort are gathered for tea [2]. St John’s wort takes its English name from St John, whose feast this night is.

To prepare: The weeks when St John’s wort flowers. Dry what you gather in the shade; St John’s wort interacts with many medicines.

Lughnasa and Bilberry Sunday

The first harvest in Ireland: people climb the hills to pick bilberries and eat the first new potatoes.

Lughnasa, the first-harvest festival of the Celtic calendar, was celebrated in Ireland between the last Sunday of July and the first Sunday of August. After a meal people climbed the hills to pick bilberries (fraochán); they ate them on the spot, strung them into bracelets and necklaces for sweethearts and carried some home for the old. Picking after the first Sunday of August was forbidden, as fairies were believed to spoil the fruit. It was also the day the first new potatoes were eaten [1].

Day of the Dead (Día de Muertos)

The days in Mexico when the dead return home: marigold petals and copal smoke show the way.

In the Indigenous communities of Mexico, from the end of October to the beginning of November, families welcome their dead back home. Petals, candles and offerings are laid along the path from the cemetery to the house; flowers and the dead person’s favourite dishes are placed on the home altar and the grave. The festival also marks the end of the yearly maize cycle [1]. The main flower of the altar is cempasúchil (marigold), whose Nahuatl name means “twenty flowers”; its scent is believed to guide the souls. Copal resin and incense cleanse the space and drive away bad spirits [2]. UNESCO inscribed the festival on its Intangible Cultural Heritage list in 2008 [1].

To prepare: Marigolds (Tagetes) are sold as ornamentals in autumn; their orange petals give the altar its colour.
