Gardenia: Eterna City's Grass-type Gym Leader, terrified of ghosts

A greenhouse Gym, a forest badge, and a Gym Leader who doesn't dare set foot in a haunted chateau. Gardenia guards the second gate of the Sinnoh League and fields nothing but Grass-type Pokémon in her Gym, singing their praises without ever denying their weaknesses. The paradox fits in a single sentence: she prowls around the Old Chateau to get to the bottom of the rumors, yet the mere thought of a Ghost-type Pokémon makes her back away.

Eterna City, the Forest Badge and a Gym That Feels Like a Greenhouse

Gardenia runs the Gym in Eterna City, in Sinnoh. Anyone who comes out on top leaves with the Forest Badge, the second official badge of the regional challenge — an early step, then, in the player's progression.

The place is nothing like a neutral gymnasium: it's a courtyard planted with grass and trees in Diamond and Pearl and their remakes, replaced in Platinum by a course split into four quarters by a giant clock. The house specialty is obvious before the first Poké Ball is even thrown.

How the encounter is staged depends on the version. In Platinum, Gardenia stands outside, in front of the entrance — in Diamond and Pearl as well as in their remakes, she waits for the challenger inside the Gym.

Passionate About Grass, Terrified of Ghosts

She makes no secret of her devotion to the Grass type: she adores it despite its many weaknesses, and she's interested in anything even remotely connected to it. It's the stance of a believer rather than a calculator, and that's exactly how the game presents her.

Eterna Forest draws her in for another reason: the rumors surrounding the Old Chateau. She goes there often and circles the building — but never sets foot inside. Ghosts and Ghost-type Pokémon terrify her, something she does her best to hide.

The mobile game sums up the character along the same lines: a perpetually cheerful but frankly fearful Gym Leader, whom a single Ghost-type Pokémon would be enough to petrify. The irony is complete in the Sinnoh remakes, where she teams up at the Battle Tower with Fantina, the Gym Leader whose specialty is precisely that type.

Rematches, a World Tournament and a Mobile Career

Once defeated, Gardenia is still around. In the Brilliant Diamond and Shining Pearl remakes, her Gym reopens for one rematch per day, but only after you obtain the National Pokédex. In Platinum, she also takes on all comers at the Battleground in the Survival Area, far from her home turf.

Black 2 and White 2 enter her in the Pokémon World Tournament, where she appears in several brackets, including the Type Expert Tournament devoted to her type and the Sinnoh Leaders Tournament. Her roster adapts to the format — three Pokémon in Single Battles, four in Double Battles and Rotation Battles, all six in Triple Battles — and both their gender and their Ability change from one battle to the next. A win earns one Battle Point.

The mobile game recruited her from launch day, in her canonical outfit and paired with Roserade. She later got a summer variant: a pirate costume, a treasure hunt on Pasio and Dhelmise as her partner — enough to take her out to sea, which was far from a given.

In the Anime, Uncontrollable Enthusiasm

The series casts her as a guide: she's the one who helps Ash find the Amber Castle. Her dominant trait is played for laughs there, since she flies into near-hysterics at the sight of any Grass-type Pokémon that crosses her path.

Her reputation as a coach earns her an unexpected show of trust: James leaves his Cacnea with her so it can train at her side and come back stronger. Team Rocket rarely delegates, and never lightly.

She then tries to get that same James's Carnivine in a trade, putting the best she has on the table: a Victreebel, a Bellossom and a Vileplume. In battle, she's seen relying on Cherubi and its Chlorophyll Ability, while her Roserade strings together Grass Knot, Magical Leaf, Flash and Weather Ball.

In the Manga, a Strategy Turned Against Her

The print adaptation brings her in during the Diamond and Pearl arc, with Roserade and Cherubi at her side. She senses a "Gas Pokémon" lurking around the Old Chateau and, when the heroes coming out of it won't listen, she trips them up with Grass Knot to hold them back. Learning that they took down a Gastly terrifies her as much as it impresses her; she then reveals that she's a Gym Leader and tells them to meet her at the Gym.

The next day's duel takes the form of a Double Battle against Platinum, who sends out Ponyta and Prinplup. Gardenia fights from a distance: her Roserade sends its poisonous thorns racing beneath the ground, knocks Ponyta out in no time and batters Prinplup with Grass-type attacks.

Confident in her position, she advises her opponent to give up and follows up with Cherubi's Grass Knot. Platinum thinks it over, then uses the tunnels dug by Roserade to send a Blizzard through them: both of Gardenia's Pokémon go down in a single blow. Surprised to see her own plan blow up in her face, she graciously hands over the Forest Badge.

What follows is far less lighthearted. Gardenia takes on the Team Galactic Commanders alongside Roark and Fantina, holds out for several more chapters, then falls wounded — but not before giving Platinum a Cherrim as a token of friendship. Hospitalized throughout the following arc, she only appears in the heroine's thoughts, along with the other Gym Leaders, before making a full recovery in the epilogue.

A Starter, an Early Evolution and Trading Cards

One quirk sets her apart from all her colleagues: she is the only Gym Leader to field a starter Pokémon from the very first battle, in this case Turtwig. That privilege is usually reserved for rivals and members of the Elite Four.

Another departure from the usual rules: in Platinum, her Cherrim has already evolved at level 20, whereas a Cherubi normally only evolves at level 25. The game thus gives her a five-level head start on the standard curve.

The trading card game featured her in two stages. Her Pokémon were illustrated first, in the Platinum—Rising Rivals expansion, released in France on November 6, 2009; the Gym Leader herself had to wait for the Sun & Moon—Ultra Prism expansion, released on February 2, 2018.

One more resemblance players have picked up on: Gardenia looks a lot like Colza, a character from Pokémon Legends: Arceus, and both of their Japanese names refer to rapeseed. No connection between the two has ever been officially confirmed, though.

• What is Gardenia's signature Pokémon?
  Roserade. It's the partner paired with her canonical outfit in the mobile game, and the one that leads her battle against Platinum in the manga.
• Does Gardenia really use a starter Pokémon?
  Yes, Turtwig. She is the only Gym Leader to field one from the very first battle, whereas starters are usually reserved for rivals and high-level Trainers.
• What happens to Gardenia in the manga?
  After her defeat against Platinum, she takes on the Team Galactic Commanders with Roark and Fantina. Wounded, she gives Platinum a Cherrim before losing consciousness, stays in the hospital and then recovers in the epilogue.

In short

Gardenia holds a special place among the Gym Leaders: she adores her type without ever denying its many weaknesses, and she's one of the few whose admitted flaw — her fear of Ghost types — shapes the character as much as it shapes her team. The manga takes that logic all the way, having her lose her duel to her own strategy, then sending her to the front lines against Team Galactic. A plant specialist who's better at battling than at keeping her nerves in check.
