Golden Flowers

Golden Flowers are a type of flora found throughout the game as a recurring symbol in Undertale.

Description
Golden Flowers have corollas with five to six yellow petals. They grow on individual stems and appear to grow in patches as well. Golden Flowers are indigenous from the surface and can easily adapt to new environments, as seen when they grow in the Garbage Dump. Their sticky seeds helped them to be brought to and spread throughout Underground. They can be used to make tea.

Main Story
Golden Flowers can be seen throughout the game, mainly in the Ruins, in the Garbage Dump and in New Home. They are first seen when the protagonist falls on them at the beginning of the game. They cushion their fall after Undyne cuts the bridge above the Garbage Dump too.

A prominent member of Golden Flowers is Flowey. Alphys experimented with determination with many vessels, Golden Flowers among them. Alphys injected determination on the first flower to bloom, which had Asriel's dust; shortly after this the flower was gone. Flowey also mentions how he woke up as a flower in the very same garden where that flower grew.

Flowers can also be seen in Asgore's Home (foyer, drawing in children bedroom, Asgore's bedroom, dining room) and Toriel's Home (places 4 and 5)

Trivia

 * Golden Flower tea is Asgore's favorite kind of tea.
 * A common misconception is that Golden Flowers are buttercups, like the ones Chara and Asriel mistakenly put on a butterscotch pie. This is impossible since Golden Flowers were brought to the Underground only after Chara's death.
