Grand Printemps (グランプランタン Guran Purantan?) is the fourth group attack shown in the Go! Princess Pretty Cure series. It is first used in episode 39 and it requires the Royal Key and the Music Princess Palace to activate the attack.
The four Cures surround the Music Princess Palace and insert the Royal Key into the palace. Cure Flora turns the dial and the Cures transform into their Royal Premium Elegant Modes within the palace. They pose by themselves after the transformation is completed before forming a group pose together. The palace comes out of the ground behind the enemy and Cure Flora sweeps her right arm toward the enemy to make the enemy have lace plates below and above them float upwards. Together, the Cures say the incantation while flying upwards into the sky. They come flying out of a gold crown in their own respective theme colors glowing around them while saying "Pretty Cure Grand Printemps!" in which they fly through four lace plates in the theme colors of the Cures before crashing into the enemy. The crash makes the area turn into a field of flowers, and Flora appears in a hurricane of rose petals, which fly away and fireworks of petals rain down on the Cures as they curtsy and Flora says "Gokigen'you", purifying the enemy.

- Much like Trinity Lumiere, a different Cure says "Gokigen'you" depending on who the episode focuses on.
