PlantSnapp utilises a network of horticultural experts and a database of 6,000 plant species in order to correctly identify the plant.
Features include GPRS aided photo recognition and direct links to mail order plant nurseries in the UK.
The app is the idea of George Williams, 23, a botanist with a passion for technology, and serial entrepreneur co-founder Angus Rankine.
Williams said "We want people to have access to any plant that catches their eye at the touch of a button and if we can boost the popularity of gardening as a result and in turn make Britain a greener place that would be a wonderful achievement."
PlantSnapp is in partnership with the UK's Bumblebee Conservation Trust, which is striving to save and reinvigorate bumblebees in Britain. PlantSnapp can identify and recommend plants that are especially nurturing for bumblebees.
Williams said: "At a time when curiosity can be so easily satisfied by the devices almost all of us carry with us, PlantSnapp is a game changer in the way in which people interact with the world around them and will bring the world's plants to people's doorsteps."
For the future, PlantSnapp plans to launch automated identification once a strong database has built up and augmented reality integration.
The app will also be available in other territories from January 2015. PlantSnapp is available for the iPhone and iPad on the App Store.
