It's easy to find a garden you like anywhere in Paris, there will be one nearby, the well known: Jardin des Tuileries, Jardin du Luxembourg, Jardin des Plantes, Parc du Champ de Mars (the one next to Eiffel Tower); or Parc des Buttes-Chaumont, Parc laVillette...,etc.Some others are more private, like this one inside Musée Rodin, or the one in Maison et Jardins de Claude Monet. But from time to time when I pass the streets, other forms of "garden" can be found.
Here they are, somewhere near the Saint Paul's Village, so cool, right? Looks like an unfinished painting on canvas, more to go & imagine!Or, most of the times, you will find small flowerbeds are right next to your appartment, along the street or at most of the Parisian's balcony. It's difficult for me to miss any of them because they are so flourish and attractive. 
And you will never be disappointed because, here in Paris, people not only create their own garden wherever possible, but take great care and keep cultivate, that's why they are always look amazing. If the same theory applies to the secret garden in our heart, I am sure it works 101%, too!
