Cascanna

Casclausas are instant-use, environment modifying flower plants that create a water tile, as well as damaging zombies.

Overview
When Casclausa is planted, a cross-hairs shows up. The player can then aim the cross-hairs at any tile in Casclausa's row. This will create a water tile there. This will also deal 2 damage to any zombie there, and it will also render them immobile for 5 seconds.

Cascanna is based on the Hosta clausa. Its name is a portmanteau of "cascade" and "clausa."

Strategies
Casclausa should only be used if the player has also chosen aquatic plants. Otherwise, the player would need to bring a Lily Pad to actually plant stuff in the water tile, and that's just redundant and a waste of sun.

Trivia

 * Casclausa was originally named "Cascanna," but what it was based on was forgotten, so its name had to be changed to resemble that of a similar looking plant.
