Although going from not even having an aquarium to having a planted one may seem very daunting, in reality it simplifies maintenance. When I did not posses aquatic plants, I changed my water much more often than when I implemented aquatic plants into my tanks. For example, I used to change my water every to weeks and now it's every month or so! And that is because I use terrestrial plants (house plants) like pothos in some of my tanks. Of course, I have very lush tanks with aquatic plants, but terrestrial plants help much more because they have much more developed root systems than thier aquatic counterparts. Therefore, I firmly believe that anyone can implement aquatic or terrestrial plants in their tanks, if they are willing to learn and make adjustments. 

What aquatic plants would I recommend for beginners? Well, I would say my favorite aquatic plant for beginners and in general is anubias. Its hardy, doesn't require much light, and finally it has beautiful broad leaves! The only problem is its price because it takes a while for it to grow and it is in high demand, making more pricy than other plants. Nonetheless, it is better than to keep repurchasing some finicky plant that is harder to grow for beginners. Also, note that anubias is an epiphyte, which means it grows best tied on decor. Another great plant for beginners is Amazon frogbit. This is a floating plant, meaning that it's really good at absorbing fish waste. This plant has nice broad leaves and would be a great addition to any beginner tank! Please make sure there is no duckweed attached to your Amazon frogbit because duckweed grows scary fast and will take up surface of your tank. 

This is a great example of an intermediate level tank that utilizes plants like anubias, rotala, and subwassertang.
