Welcome to GardenSearch!

Locate botantic gardens around the world

Providing gardens with a visible web presence, even when they don't have a website, GardenSearch is the only global source for information on botanic gardens. The database includes information on over 3,531 botanical institutions worldwide.

GardenSearch allows you to:
