Grimrose

Grimrose is the fifth and last plant obtained in Modern Day. It instantly kills the strongest grounded zombie on the lane (but deals only 30 normal damage shots to Gargantuars and mechanical enemies) by dragging it into the ground, regardless if it is behind or in front of this plant. When powered by Moonflower, Grimrose can defeat up to three enemies before disappearing; the remaining charges are represented by stamens on Grimrose's head. If a powered Grimrose is depleted of its shadow field, it will temporarily lose its charge and be only capable of defeating one enemy before expiring. The charges will be restored when Grimrose is repowered.

Origins
Grimrose is based on the Onagraceae, a family of flowing plants commonly referred to as evening primroses. Its name is a portmanteau of grim, referring to the way it defeats zombies and primrose, the real-life plant this plant is based on.

Almanac entry
Grimroses are shadow plants that behave like landbound Tangle Kelps, dragging zombies into the dirt.

Special: powered Grimroses can drag 3 zombies before expiring.

"When you think about it, the proper place for a zombie is in the ground," says Grimrose. "So, really, I'm just expediting the process."

Plant Food effect
When fed with Plant Food, Grimrose drags the strongest grounded zombie on the lawn into the ground. If Grimrose targets a Gargantuar or a mechanical enemy, it will only deal 30 normal damage shots to it. This action does not remove any stamens from Grimrose.

Strategies
While it is truly better than Tangle Kelps since these can be used anywhere, its downside is the extra 50 sun needed for planting, and another 50 sun if a Moonflower is used along with this and its Plant Food ability, which only drags one zombie. It is also better than Tangle Kelp in terms of the following: range, which zombie it drags and recharge speed.

Like with Stunion, you have a short time to dig Grimrose up before it disappears. Try digging for refunded sun.

It is recommended to bring this plant with a Moonflower so you don't have to replant these all over again. Bring this plant with Shadow-shroom when you are playing La Brainsa Tarpits, as this combo can be useful. Shadow-shroom will poison and kill the headwear zombies, while Grimrose can focus on damaging the Gargantuars or dragging down the Bullies.

Aside from prioritizing the strongest zombies first, it can also drag the zombies behind it, making it useful against Imps thrown by Gargantuars and Bulls or kicked by All Stars; zombies carried by pterodactyls, launched by Stegosauruses, or kicked by raptors; or Prospector Zombies that reach the back.

Like Shrinking Violet, this is a great Gargantuar staller, since it cannot be smashed while dragging zombies down.

Trivia

 * Grimrose's Almanac says "the proper place for a zombie is in the ground," alluding how zombies usually rise from tombstones or the ground.
 * Its straw hat costume resembles the Asian conical hat, a type of conical hat.
 * If a Plant Food is used on a Grimrose with zero stamens, the plant will perform its Plant Food effect, then be able to defeat one more target before expiring.
 * Its description is slightly misleading, as it actually functions quite differently than Tangle Kelp:
 * While Tangle Kelp can only grab a zombie from a close range, Grimrose can grab any zombie in its lane, regardless of distance.
 * Grimrose targets the strongest zombie in its lane, while Tangle Kelp simply grabs the first zombie that touches it.
 * Its French name, being "nécRose", is a play on the word "nécrose" (necrosis) and "rose", referring the fact that zombies are mostly depicted as dead.
 * Grimrose's stamens show how many zombies it can pull underground.
 * Grimrose won't die when it was smashed by a Gargantuar or gets eaten by a zombie. It will only die when it already pulled the amount of zombies it can pull.
