What plant shoots two peas at once?

The plant that shoots two peas at once is the Repeater. It is an upgraded offensive plant in the original Plants vs. Zombies, firing two pea projectiles in quick succession down its lane.

The Repeater costs more sun than the basic Peashooter, but its doubled output makes it useful when a lane contains tougher or more numerous zombies. Like the Peashooter, it fires straight ahead and must be planted on a lawn space with a clear line toward approaching enemies.

Several answer choices are easy to mix up. Gatling Pea is an upgrade that fires four peas, while Threepeater fires one pea into each of three lanes. Peashooter fires only one pea at a time. These plants all belong to the same projectile-focused family, but their firing patterns are different.

The Repeater also interacts with support plants. Planting Torchwood in front of it converts its peas into fireballs, increasing their damage and producing an especially effective attack against groups. The original game lists Repeater among its 49 available plants and uses it as a straightforward example of how upgrades can improve a basic defense.
