What Is Plant 43 in Resident Evil 9?

Plant 43 is a callback to the classic Plant 42 from the original Resident Evil, but massively enhanced through modern parasitic bioengineering. This towering botanical mutation has rooted itself at the surface entrance to the ARK facility, spreading thick vines across the surrounding area. Unlike other bosses in RE9, Plant 43 is a stationary target, but its reach extends across the entire arena through its vine network.

Key characteristics of the RE9 Plant 43 boss:

• Structure: Three side buds (left, right, upper) act as shields for the central middle bud
• Middle bud HP: Approximately 8,000 HP (12,000 HP on Professional), but only takes damage after all side buds are destroyed
• Side bud HP: Each side bud has approximately 2,500 HP (4,000 HP on Professional)
• Vine attacks: Long-range vine whips and root eruptions that cover most of the arena
• Pollen cloud: Periodic toxic pollen release that deals damage over time if you stand still

How to Beat Plant 43: Bud Targeting Strategy

Step 1: Destroy the Left Side Bud

The left side bud is the most accessible target and should be your first priority. It sits at roughly eye level on the left flank of Plant 43's main body, glowing with a faint green luminescence.

How to target the left bud:

1. Position yourself at the left side of the arena behind the concrete barrier
2. The left bud opens and closes on a 5-second cycle. Shoot only when it is open (glowing brightly)
3. Use the shotgun at close range or handgun at medium range
4. After taking damage, Plant 43 retaliates with a vine whip from the left. Dodge right to avoid it
5. Three to four shotgun blasts or eight to ten handgun shots will destroy the left bud

Step 2: Destroy the Right Side Bud

The right side bud is slightly higher and partially obscured by thick vine growth. You need to reposition to the right side of the arena to get a clear shot.

How to target the right bud:

1. Move to the right flank, using the overturned vehicle as cover
2. The right bud has the same open-close cycle but is offset from the left by 2 seconds
3. Watch for the Root Eruption attack: Plant 43 sends roots bursting through the ground in a line toward you. Sprint perpendicular to the eruption path
4. Fire at the right bud during its open window, using the same weapons as before

Step 3: Destroy the Upper Side Bud

The upper bud is the most challenging target because of its elevated position and the increased attack frequency at this stage of the fight.

How to target the upper bud:

1. Move to the elevated platform at the back of the arena (accessible via the metal staircase)
2. From this platform, the upper bud is at eye level and clearly visible
3. Plant 43 becomes more aggressive with two buds destroyed, using vine whips and root eruptions simultaneously
4. Time your shots between attack patterns. The upper bud has a longer open window (7 seconds) to compensate for the increased difficulty

Step 4: Destroy the Middle Bud (Final Phase)

Once all three side buds are destroyed, the central middle bud fully opens, revealing a pulsating core. This is Plant 43's true weak point, and it takes full damage from all weapons. However, Plant 43 enters a frenzy state with significantly more aggressive attacks.

Middle bud strategy:

1. The middle bud is now permanently open and glowing bright red
2. Plant 43 uses all vine attacks simultaneously: whips from both sides and root eruptions in rapid succession
3. Stay on the elevated platform for the best angle on the middle bud while maintaining distance from vine whips
4. Use your magnum and remaining grenades for maximum damage output
5. The middle bud takes approximately 8-10 magnum shots or 15-20 shotgun blasts to destroy

Plant 43 in the Context of RE9's Boss Design

Plant 43 represents a shift in RE9's boss design philosophy from direct combat to environmental puzzle solving. Unlike action-heavy encounters such as the Titan Spinner, this fight rewards observation and methodical target prioritization. The bud destruction order mechanic also foreshadows the multi-stage strategies required for The Commander and the final boss encounter later in the ARK.

Frequently Asked Questions

Does it matter which side bud you destroy first?

No. You can destroy the three side buds in any order. However, the left side bud is the easiest to target due to its accessible position and clear line of sight, so starting with it is recommended for efficiency.

Can you damage the middle bud before destroying all side buds?

No. The middle bud is completely protected while any side bud remains active. Shots that hit the middle bud before all side buds are destroyed deal zero damage. Focus entirely on the side buds first.

What is the best weapon for Plant 43?

Incendiary weapons are the best choice because Plant 43 takes 2x damage from fire. The Grenade Launcher with flame rounds is the single most effective weapon. If you do not have flame rounds, the shotgun is a reliable all-purpose alternative for close-to-mid range bud targeting.

How do you avoid the Root Eruption attack?

Watch the ground for cracks and dust particles rising from the soil. These visual cues appear approximately 1.5 seconds before roots burst from the ground. Sprint perpendicular to the direction the cracks are spreading. The roots always travel in a straight line from Plant 43 toward your last known position.
