Description

Title:
Platycodon grandiflorus 'Astra Pink' flower [UV]
Caption / Description:

Ultraviolet photo of the flowers of a Platycodon grandiflorus 'Astra Pink' plant. In ultraviolet light the stigma is quite dark, contrasting with its bright white appearance in visible light. The withered stamens around the edge at the centre of the flower also appear much darker in ultraviolet than they do in visible light. The veining on the petals is very slightly darker in ultraviolet than in visible.

Platycodon grandiflorus is commonly known as the balloon flower because of the way its flower buds swell up like a balloon before they open. The Astra Pink cultivar has light pink coloured petals in visible light. The five petals, which are joined at about half their length, form a star shape when the flower is fully opened.

At the centre of the flower is a five lobed stigma, surrounded by five stamens. In the flower in this photo the stamens are withered. The stamens mature before the stigma, in an effort to avoid self pollination.
