Plants VS Zombies 2 plant suggestions

I have a plant idea.

Spinecone 
Sun cost: 175
Toughness: 2500
Range: 1 tile in every direction
Basically a beatroot and endurian combined.
Description: Looks like a Pinecone.
Effect: When zombies get near it attacks every 1-2 seconds. Could have a small piercing effect. When zombies start eating it it starts to damage them a bit like the endurian but less damage.
Plant food: makes a column of spines up down left and right and starts spinning in circles.
