International Garden Photographer of the Year is the world's premier competition and exhibition specialising in garden, plant, flower and botanical photography.

International Garden Photographer of the Year is wholly owned and organised by GALPA Ltd.

It is run in association with the Royal Botanic Gardens, Kew, United Kingdom. The main exhibition is held annually at Kew, with a rolling programme of touring exhibitions in the UK and all over the world. Exhibitions are linked to events such as workshops and lectures on garden photography.

The competition closes on November 30th each year. WInners are announced at the opening of the Kew exhibition, the following March. The following year's competition is launched at the Kew exhibition.

In addition, there are seasonal categories with results announced four times a year ('4 Seasons').

The competition is open to everyone anywhere in the world. Images do not have to be taken in a specified year. There is no distinction drawn between professional and amateur photographers.

There are eight categories to enter and a special section for people under 16 years of age.

There is a fee for entering the competition which helps to cover the expense of mounting and touring the exhibition. This fee is £10 for 4 single images, or £25 for a portfolio. Under 16s can enter for free.

A book of the exhibition is normally produced each year.
