Astro-Shroom is a galactic super-rare plant card in Plants vs. Zombies Heroes, and a member of the PvZH Kabloom IconKabloom class. He costs 1SunPvZH to play, and has 1StrengthPvZH/1HeartPvZH. He has the PvZH Truestrike IconBullseye trait, and his ability does 1 damage to the zombie hero every time a plant is played. This ability stacks with each Astro-Shroom on the field, and persists until all Astro-Shrooms are removed from the field.


He is based on an asteroid, a minor planet that does not show characteristics of a planet or active comet, and a mushroom, the fleshy, spore-bearing fruiting body of a fungus.

His name is a portmanteau of "astro-," referring to his appearance and him being in the Galactic Gardens set, and "mushroom," the real-life fungus he is based on.


  • Class: Kabloom
  • Tribe: Mushroom Plant
  • Trait: PvZH Truestrike IconBullseye
  • Ability: When you play a Plant, do 1 damage to the Zombie Hero.
  • Set - Rarity: Galactic - Super-Rare

Card description

He's had good meetings with a lot of smaller asteroids. They really made an impression.

  • Added to the game.



Although Astro-Shroom has average stats for his cost, his ability can do easy damage to the zombie hero, especially in rush decks. To fully utilize his ability, use cards that make more plants when played such as Shroom for Two, Pair of Pears, Mushroom Grotto, just to name a few. These, in turn, allow Astro-Shroom to do more damage the more plants are made on the field without charging the Super-Block Meter thanks to his PvZH Truestrike IconBullseye trait.

However, he has very low stats, meaning he can perish easily in the late game. To avoid this, it is best to play him behind a Team-Up plant like Puff-Shroom to protect him, or boost him to improve his survivability. Spudow and Captain Combustible can boost his health with cards such as Photosynthesizer and Fertilize. However, take note that his ability only does 1 damage to the zombie hero for each other plant played, regardless of his strength. If you don't think a stat boost is viable, nor do you think he will be of much use, try Evolving him, as he will still activate his ability before Evolving.

It is also worth noting that Astro-Shroom is a mushroom, so he benefits from Buff-Shroom, who gives him a small boost, and Punish-Shroom, who applies pressure to the zombie hero so they won't hastily destroy Astro-Shroom.

Speaking of Captain Combustible, you can use this in tandem with Muscle Sprout. Playing many cheap plants allows Astro-Shroom to do damage as well as boost Muscle Sprout, making the two together very dangerous threats on the field. Spudow has access to many cheap Team-Up cards, which work well with Astro-Shroom. On top of rushing defensive cards, playing Poppin' Poppies can do 4 damage to your opponent all at once, due to her ability.

Because he doesn't charge the Super-Block Meter when he activates his ability, playing this on Planet of the Grapes can guarantee you to draw a card whenever you play a plant, thus making sure you will not run out of cards while you are rapidly deploying plants. However, keep in mind that only Nightcap can do this normally, and other Kabloom heroes will have to rely on High-Voltage Currant for a chance to get Planet of the Grapes.

Another strategy is combining him with Pair Pearadise, which creates two Astro-Shrooms, both of which will damage the zombie hero when a plant is played.


This plant can damage the zombie hero quickly, as the plant hero will often play swarms like Shroom for Two to do cheap damage to the zombie hero without charging the block meter. In that case, try to destroy this plant as quickly as possible to avoid taking lots of damage. Using tricks like Bungee Plumber or Rolling Stone is the most effective way of taking him out, along with zombies such as Conga Zombie.

The best way to neutralize this plant is using Planetary Gladiator as both Astro-Shroom's regular attack and ability will be completely absorbed by him, plus Planetary Gladiator himself will take no damage due to his PvZH Armored IconArmored 1 trait.

Always remember that the PvZH Truestrike IconBullseye trait works with abilities, so don't rely on the Super-Block Meter to save you from this plant.



  • Occasionally, a mushroom of an unknown species pops out of one of Astro-Shroom's craters, then hides.
  • He is the first PvZH Truestrike IconBullseye plant in the Kabloom class. The second is Gloom-Shroom.
    • He is also the first PvZH Truestrike IconBullseye plant outside of the PvZH Guardian IconGuardian class.
    • This means that Spudow currently has access to the most PvZH Truestrike IconBullseye plants out of all plant heroes.
  • His description makes a joke out of the double meaning of the word "impression," which means "effect on someone," but also "a mark impressed on the surface of something," referencing the way that smaller asteroids collide with larger space bodies, which Astro-Shroom resembles, leaving craters on their surface.
  • If Astro-Shroom attacks twice with its ability consecutively, say with Shroom for Two, it will play its fireball animation once, then shoot out its normal attack, but still play its fireball animation again, even launching the fireball. However, this still only sums up to two damage.
  • The projectile, animation, and sound effects used when Astro-Shroom activates his ability are the same as those used in Solar Flare's signature superpower, Sunburn.
  • During development, its ability activated only when a mushroom was played.
  • Astro-Shroom will activate his ability even if a plant with an Evolution ability is played on him.
