At the start of combat, Cymbidiums' skill is announced seperately from other activation rate effects, so I get the 1.2 activation rate anouncement from Geranium, and a seperate 2x activation rate announcement from Cymbidium. How those two combine "under the hood" I really can't say. Could be either 1.2 + 2 = 3.2 or 1.2 * 2 = 2.4. But the result is generally 4 or 5 skill activations on that first turn for me.
