Nightbloom

Nightbloom is the sixth plant obtained in Modern Day in Plants vs. Zombies 2 and the first plant obtained in Part 3. Due to its being a shadow plant, it can be powered by and power Moonflower. It shoots lasers out of its eyes every 2 seconds that cover a special area with decreasing damage based on distance. Its lasers last 4 tiles and deal 3 damage in a 1x1 area to the initial zombies hit and then do 1 damage over a 3x3 area. When powered by Moonflower, it shoots one laser every 2 seconds that does 6 damage to the initial zombies hit in a 1x1 area. The laser splits into three lasers which do 3 damage over a 1x1 area for two tiles. The top and bottom lasers then split into 2 for a grand total of 5 lasers which each do 1.5 damage over a 1x1 area. The lasers pierce through zombies which makes Nightbloom an area-of-effect plant.

Origins
Nightbloom is based on the double-bloom Midnight Ruffles hellebore. This refers to its double bloom when powered and its name. The 'midnight' part inspired the appearance change when powered.

Almanac entry
Nightbloom shoots a splitting laser beam down the lane.

Special: powered Nightblooms shoot better splitting laser beams

Many people wonder why Nightbloom can only bloom with Moonflower. But then they wonder why she even can bloom. In the sunlight.

Plant Food effect
When fed Plant Food, it will open up regardless of its state. When not powered, it will shoot 10 lasers which each deal 20 NDS across a 1x1 radius in a random one of the 2/3 closest lanes in front of it. When powered, it will create 5 portals and shoot these lasers out of any one portal at a time, 20 times over.

Costumed
The lasers now do damage across a 3x3 radius.

Strategies
This plant is not to be ignored. Its damage makes it an amazing early-use plant if you can get the sun. Once powered, however, most things will get taken down easily. Zombies with high health (such as Gargantuars) are best finished by another plant due to the randomness of its Plant Food effect, however. In other words, use it just like a Snapdragon.

Trivia

 * Nightbloom is the only shadow plant to drastically change appearance when powered.
