Cancer Jalap

The Cancer Jalap is a poison plant. On it's sides are nine pink flowers. These "special" flowers are very poisonous and contains poison simular to heroin. When a zombie aprroches a tree, it pucks a flower, thinks it's a brain, and eats it. The poison causes it to slowly die, and it leaves the tree alone, afraid that it will poison it again.

Once the Cancer Jalap runs out of flowers, the zombies proceed to attack it. It's health is normal. If a gigantuar attempt to kill it when it still has flowers, the flowers will quickly release poison, so when it dies, and surroundng plants are infected.

Strategy
Try putting the plant in the front row, so it's easier to finish off.

Or, you could put it at the end for defences if it makes it through your defense.
