Flower hunt

In the northernmost coldest and darkest region of the world where most of the year it's cold and frozen they celebrate the short summer months by dedicating a couple of days to the Flower hunt.
The flowers in the cold regions are scarce and short lived.
The Flower hunt is one of the biggest and most loved celebrations in the northern regions. It signifies the brightest and most abundant times of the year. There is an abundance of prey, berries and fruit.
The adults hunt, while the elders and children gather fruit, berries, flowers and branches of green leaves. They use the flowers and branches to decorate themselves, their houses and surroundings.
They make wreaths, garlands, weave it into their fur and hair and place leaves and flowers in colorful patterns on various surfaces.
Teenagers that haven't found a mate yet are often encouraged to celebrate the Flower hunt with other tribes

Execution

When the abundance is noticed in nature everyone is set to pitch in. They gather as much as they can. Flowers Berries and meat.
When the gathering is done, after 2-3 days, the decorating is made on the 3rd or 4th day.
On the evening of the decoration day a bonfire is lit.
They feast in the midnight sun, they eat they drink, find love and don't have a care in the world.
The day after is a "work-free" day. No-one is hunting or attending their normal work/chore. Instead everyone pitches in to remove the decorations, collecting all flowers and greenery and some of the leftover food.
They then bury the flowers and food as a sacrifice to their gods, praying for a calm winter and long summer.

Observance

Most tribes go by feeling. They see when the berries are abundant, the leaves are green and the prey have had their offspring.
Sometimes tribes celebrate the Flower hunt at slightly different times depending on local differences in wildlife. But usually they have all celebrated over a span of maximum two weeks.
Adults and children almost exclusively only celebrate in their own tribe. Teenagers, however often attend several celebrations if they have the chance.
