If you want to open it up a bit without taking away the premise entirely, I'd suggest a Religion Trait.
Druidic Faith: Though not a druid yourself, you were taught by druids and their faith grants you insight into the natural world. You may learn the Druidic language as one of your bonus languages due to high intelligence, or using the Linguistics skill, and gain a +1 trait bonus to Knowledge (Nature) and Survival. If you cease to revere nature, or teach another character Druidic you lose the benefit of this trait.
Which book is this listed in? I've checked the Pathfinder SRD website and I haven't found a trait called "Druidic Faith".
