Plants "will" grow in your average aquarium gravel but the size of the gravel is very important
I have a 60g and I started with fake plants when cycling but took them out after 2 days because they look rubbish so I switched to live plants left them to grow for 4weeks before adding fish it was my first ever tank with no experience. All I did is got is easy to care for plants that require no co2 or fertiliser. I have my lights on for 10hrs a day then i have a led night light for the other 14hrs. Here are the plants I have, all available from aquarium gardens (UK) just type it in Google. Java fern, Anubias coffefolia, Anubias Nana, flame moss these all attach to wood or stone and are a very healthy looking dark green. ludwiga repens, ludwiga repens Rubin, rotala rotundifolia, Echinodorus Ozelot Red Flamed all of these are red and green substrate plants. Sagittarius platyphylla, Vallisneria Spiralis and dwarf hair grass are planted into the substrate. I also have no special substrate for plants all I use is CaribSea Black Tahitian Moon Sand. Hope this helps
I have a 23 gallon tank and have just placed an order for heaters, filter pump, gravel and lighting rig, just so I can explore the idea of maintaining an underwater garden. The good news is, I am part of a team. My partner wanted fish for our boys, I’m a keen gardener. Neither have kept fish before but between us I am sure we will manage. Worse case scenario; the fish die, the plants get used as compost material for my allotment and the aquarium becomes a formicarium and I move in a colony or two of lasius flavus or lasius niger.

How to plant grass in my freshwater aquarium - Quora
The typical aquarium comes with one light in the hood (aquarium cover). If you would like to grow aquatic plants spend the money to get a fluorescent hood as fluorescent lighting more closely emulates the sun than does incandescent lighting. A starter tank is generally set up with a gravel substrate with or without an under-gravel filter. You will be able to grow aquatic plants either way. Medium or fine gravel is better than chunky.The most common mistake made by beginners is to get the cheapest gravel they can find and a month later we ask ourselves why the plants are not growing well. A good quality substrate can be costly but will pay off in the end. All plants need a supply of Iron (Fe) to grow. Substrates such as and provide a long lasting supply of Fe to the plants through the roots. While each of these products can be costly per bag to buy, it provides you the best start to growing nice plants. I personally have used both with great success. Plants "will" grow in your average but the size of the gravel is very important. It needs to be a finer grain in size and it will also need to be fertilized to provide the nutrients to the plants. I would suggest a layer of peat and Laterite under regular aquarium gravel or sand to provide the Fe needed by the plants. When using this method you must take care not to disturb this layer over time. If it is disturbed and allowed to enter the water column you could create "nuisance algae" problems.
