Rhubarb

Rhubarb is a premium  plant in Plants vs. Zombies 2. It was released alongside the Viennese Classics Part 1 teaser in Piñata Parties  and is available for purchase at $4.99.

Rhubarbs will merge zombies 2 tiles beside it into one group in one tile. After it merges, it's hands will pierce 3 normal damage shots to every zombie in it, then disappear into a small cloud.

Etymology
Rhubarb is based on the vegetable, or fruit in the United States of the same name, in the family Polygonaceae. Rhubarbs are often cooked as pie and can be infused with fruit juice. It is mostly infused with strawberry juice. It's spiky hands are meant to represent the spikes on barbed wires, where any person or animal that attempt to pass through or over it will suffer injuries or discomfort.

Rhubarbs gets zombies together by giving them a spiky hug!

Special: Moves nearby zombies into one tile, then damages them

Rhubarb's feel to bring people together through hugging has gone terribly wrong with her spiky hands. Due to this, she has decided to exclusively hug only for hedgehogs, porcupines, puffer fishes, hockey and american football players.

Strategy
Rhubarbs make an excellent plant when it comes to letting AoE plants affect zombies too far away from them. Fume-shrooms,  Cherry Bombs and  Grapeshots  are highly recommended with Rhubarbs, as Rhubarbs can do it's ability to merge and add additional damage to every zombie in it's hug while the others are attacking.

Potato Mine and  its primal counterpart are also very useful with Rhubarbs, as it can defeat, or heavily damage all zombies in it. Take note that even if it will send zombies to it's left backwards, it will do the opposite to the ones in it's left, letting them skip walking two tiles, so use Rhubarbs wisely.
