Which leaves retexturing Dogwood parts, or a new static model for an apple tree being made. No offense intended toward the model from Qarl's Harvest, but its detail level is far too low and the tree looks badly out of place when encountered in the game. Not to mention a ton of UV errors and no actual apples attached to the model. Using havok apples to fill that in doesn't work, they do indeed fall off the tree long before you can touch them.
I'll see if I can get in touch with some of the folks mentioned who have Speedtree and see if they'd be willing to help out.
