The Warden's Thorn Strike has a range of Melee 2, it's keywords are Primal and Weapon. A polearm has Reach letting you attack 2 squares away.
Does a polearm's range stack with Warden's Thorn Strike for a range of 3?

They do not stack unfortunately. You need one or the other to state that "Your melee reach increases by 1"
Examples would be:
The Rules Compendium p100 reads, in the Range entry:
Melee [number]: The power can be used against a target that is within the specified number of squares of the power's origin square.
Melee weapon: The power can be used against a target within the reach of the melee weapon that is used with the power. [snip] If a creature has a reach greater than 1, the creature uses its reach for the power's range, instead of the weapon's reach. If the same creature uses a weapon that has a reach greater than 1, the creature still uses its own reach but adds 1.
So, reach weapons only add to reach when using powers with a range of Melee weapon
