Ghost Pepper. But it's not avaible anymore (so you should spare some gems in case this plant returns). Then Lava Guava! (a reverse ghost pepper).

Hurrikale is usefull in Endless Zones and Fire Peashooter is great in Frostbite Cave.

I'd say: Ghost Pepper > Lava Guava > Hurrikale > Fire Peashooter > Homing Thistle. Buy Dandelion and Sweet Potato (if they return) only if you have spare gems. Dandelion is soooo slow...
