Not always I'm afraid

I had thought about trying this combo but was worried I'd get a 14 hour mountain. After seeing a couple of successes on the forum I decided to give it a go. Stupid 14 hour tree!!! Woke up this morning at 4am when my dragons finished a 12 hour breed, tried again with my new level 7 Moss and level 7 Flower (holding my breath, hoping level 7s would be lucky) ... stupid 14 hour tree. Went to my second account, realised I have a plant habitat on this one so I can just use Plant. Mixed Plant with Moss. Stupid 14 hour tree .... EBI has just become free ... I'm wondering if I go back to breeding Airs for money for a day so that I at least feel like I'm achieving something other than breeding, yup, you guessed it ... stupid 14 hour tree!!!
