Cactus and Ash Dragons.
Breeding a flower and scorch dragon will result in 5 possible dragons which are, poison dragon, cactus dragon, flower dragon, firefly dragon, and scorch dragon.
Either buy it for 1,425 gems or breed it using the cactus dragon and the crystal dragon in the breeding cave.
You will most likely get a Firefly or Scorch. It depends on what dragon is left and what dragon is right. Lightning (left) Lava (right). That = Firefly Fire (left) Lightning (right). That = Scorch
You can only breed it in November and you need to breed cactus and firefly. The Breeding/Incubation time is 30 hours. You should check out the related link.
