To obtain a Whopperflower Nectar, you need to find and kill a Whopperflower at any level.
You can get these from any of the two Whopperflower enemies, the Cyro and Pyro Whopperflower.
The fastest way to get around is to use the Waypoints, kill everything in sight, and then move on. The two images below are where you can find Whopperflower in both Mondstadt and Liyue.
Just click on them to enlarge them.
