Sunflower Queen is a new plant boss in Plants vs. Zombies: Garden Warfare 2. She is depicted as the queen of all Sunflowers and looks similar to Mystic Flower, but with sharper petals, and is around five times larger, with white glowing eyes. Unlike most Sunflowers, her hands are spherical rather than flat.
- Royal Sun Pulse: Sunflower Queen's ranged attack. Deals very high impact damage along with significant splash damage.
- Vine Whip: Sunflower Queen's melee attack. Uses this attack twice in one sequence. Deals immense knockback.
- Sun Charge: Sunflower Queen will root into the ground and soak up sun for a short time. After she is done charging, she is able to use Solar Cannon and a charged version of Vine Whip for a short while.
- Solar Cannon: Only usable when Sunflower Queen soaks up sun. Deals extremely high damage in a constant beam, similar to Sunflower's Sunbeam.
- Sunflower Summon: Summons 3-4 Mystic Flowers as support enemies. They will automatically begin to heal her and each other in addition to attacking nearby enemies.
Super Mystic Wave
Keep in mind that unlike most bosses, Sunflower Queen does not take critical damage (Except from Super Brainz' Heroic Fists) despite her large head. Actually, all damage she receives will be reduced, no matter where she is hit. However, when she is charging up her Solar Cannon, a weak sport is revealed on her stalk, seemingly her belly, all damage dealt to this area will register as critical damage. It's best to use Z-Mech to take her out, because of the high damage she does, along with her powerful abilities. Out of all the Mechs, Z7 Mech would be the best choice, as it is able to damage her at a faster rate than other Mechs, negating her self-healing abilities, thanks to Z-8 Avenger's fire rate and damage. Captain Deadbeard is just as good at taking her out, as its Spyglass Shot has a drastically longer effective range than her Royal Sun Pulse, so don't worry about getting hit from afar. Barrel Blast is also a good way to drain some of her health, but don't let her hit you with her Vine Whip, as it will cancel out the ability instantly.
As soon as she summons her Mystic Flowers, take them all out immediately. They'll automatically start healing the Sunflower Queen and each other and can, if not stopped, heal her back to full health. Once again, Z-Mech and Captain Deadbeard are the best choices for defeating the Mystic Flowers, as Z-Mech's Robo Stomp or Z7 Mech's Zomni-Blade can instantly vanquish them, and Captain Deadbeard's Cannon Rodeo and Barrel Blast are able to damage and defeat multiple Mystic Flowers at a time.
- Unlike other Sunflowers, she usually does not smile by default.
- An exception is that her boss icon shows her smiling, while in actual gameplay she does not. She will also smile whenever her Solar Cannon charges, as well as seemingly grinning while summoning Mystic Flowers.
- Despite being a Sunflower, the Sunflower Queen does ironically not seem to be able to heal other plants.
- This is the first boss to be Sunflower-themed, with the second one being Royal Hypno-Flower.
- Both are also 2 of three female bosses, with the third being Marigold.
- Most of her audio clips are similar to Sunflower's, except her voice is lower-pitched, echo-like and is deeper than the normal Sunflower's.
- Her Vine Whip may be a reference to the Grass-type Pokémon move of the same name.
- When vanquished, her corpse has her showing a very depressed expression, which is similar to other Sunflowers but more extreme.
- She is one of the eight flowers to use her "arms" to attack zombies. The others are Royal Hypno-Flower, Morning Glory, Briar Rose, Poppin' Poppies and Match Flower Boxer.
- AI Sunflowers (whether or not summoned by the Sunflower Queen) have a tendency to prioritize her when choosing who to heal, supporting the theory of her being their Queen, given their surprising "loyalty".
