In a small bowl, whisk 3 tbsp of the olive oil with the lemon zest, lemon juice, parsley, mint, shallot, diced fennel bulb and ground fennel. Season with salt and pepper.
Heat the remaining 1 tbsp of olive oil in a medium skillet. Season the scallops with salt and pepper and cook over moderately high heat until golden brown and opaque throughout, about 3 minutes per side.
Mound the arugula on plates and top with the scallops. Spoon the fennel and lemon relish on the scallops and serve with lemon wedges.
