Flower lovers have plenty to savor this spring 2026, arriving a bit early on its bloom schedule. After the rosy magic of the cherry blossoms and the mauve curtain of wisteria, it’s now the turn of rhododendrons and azaleas to take the stage and brighten the parks and gardens of Paris and Île-de-France. From Bois de Vincennes in the 12th arrondissement to the Yvelines and across the Hauts-de-Seine, these lush shrubs put on a botanical show that photographers and walkers look forward to every year. We reveal the best spots to go and admire them.
The Parc Floral de Vincennes, the must-visit destination
In Paris's Parc Floral, inside the Bois de Vincennes, a pine grove shelters azaleas, rhododendrons and camellias that come together to form a lush living tableau.

Opened in 1969 for the Third International Floralies, it hosts nationally recognized collections labeled by the Conservatoire des Collections Végétales Spécialisées, including rhododendrons. In May, the beds blaze with color, and it's hard to leave without grabbing the camera. Outside the flowering season, the park offers mini-golf, carriage rides, and exhibitions, making it a great family outing year-round. Expect full price of €2.70 from April to the end of September, with free admission for the rest of the year. [Read more]
