The moon in May May
May is the month when the night turns soft: you can finally stay out to watch the moon climb over gardens in flower. The farmers’ almanacs call its full moon the Flower Moon, one of the most transparent names there is: everything blooms at once. In several Buddhist traditions, this same full moon is the one of Vesak. A lunar month of fullness.

What’s the lunar mood in May?
May brings the first real evenings to spend out on the terrace. The evening air holds the warmth of the day, the scents rise at dusk (lilac, wisteria, cut grass), and the moon rises late over a world saturated with green. Its light no longer falls on a sleeping landscape: it lights a garden in full swing, where the birds sing almost into the night.
The trade-off is that true darkness grows rarer: the dusk stretches out, and the full moon climbs less high than in winter. May’s moon is watched differently, less as a beacon in the dark, more as a familiar presence over the gardens.
Why the “Flower Moon”?
No mystery here: in May, everything flowers at once, and the peoples and then the farmers’ almanacs who named the full moons after the landscape simply stated the obvious. May’s full moon is the one of full meadows, orchards in petal and the first bouquets.
Depending on the region, people also said the “Planting Moon”, the month seeds were entrusted to the warming earth, or the “Milk Moon” in old Europe, when the animals found the rich grass of the pastures again. Three names, one and the same image: the month when the earth gives without counting.
What gentle rituals suit this lunar month?
The simplest gesture of the year: a walk by moonlight. In May it asks for neither a coat nor any courage, just an evening of waxing or full moon and a path you know. Walking through a landscape lit by the moon changes your sense of distance and sound; it’s an experience worth having at least once this month.
Tradition links this lunation to gratitude and abundance: you can use the full moon to list what has flowered in your life since winter, literally and figuratively. And if your windowsill has plants, look at them on the evening of the full moon: it’s the setting that makes the ritual.
And in the garden?
Once the last frosts have passed, May plants everything that fears the cold; our May garden calendar lays out the good days of the lunation.
