If I have Virizion EX in play and use Hydreigon's "Dark Trance" ability to move a Blend Energy GPRD onto a Pokemon affected by a status condition, will Virizion EX's "Verdant Wind" Ability remove the Special Condition?

Yes, it does. Any time a Grass Energy card becomes attached to a Pokemon while Verdant Wind is enabled causes Special Conditions to be removed.
