Herbs are rather hard to find until you unlock the keen eye passive. I've heard that it helps to turn off the grass, because that way, the resource nodes are more visible. If you don't want to do so, which I would totally understand, don't always run the straight line to your goal. Check near creeks and ponds, near trees, in dungeons. Target anything that looks like it could be a herb, soon you'll get the feel for it.

Even after you know what all the herbs look like there are a few that really don't stand out much, such as mountain flower.
I've also noticed sometimes mushrooms clip into the trees and roots and stuff, silly ZoS. As tiamak suggested you might find that keen eye is quite useful for those situations, even as a vet player I always have 1 point in it and don't regret it at all

Thank you for the comments guys, one more thing how do I get keen eye do I need to be a certain level??

The first level of Keen Eye is unlocked at Alchemy level 2. Keen Eye is one of the passives in the Alchemy Skill tree. You need to use a skill point and put it in that passive.

The more you play the easier it will be notice the different plants. Apart from one or two smaller flowers I can see everything without the keen eye passive. Lastly, certain plants grow in certain environments e.g. Nirnroot is often found near bodies of water.
