As posted earlier, go to an aquatic plant site (sweet aquatic is a good one) and look for "bunch plants" and see what you like and read about them.
This will help you learn more about plants.

what fast growing stem plants do you reccomend?

More sword won't work, too slow growing, you need fast growing stem plants for water safety reasons for the sake of the Betta.

ok wot about i will get more swords does it matter if there crammed toghther ??

I would get any type of stem plant-they are usually sold in bunches of 6-10 stems, lots to pick from, sword and marimo balls will not be enough to make a soil based tank fish safe
Here is a link for you to look at some stem plants and to get names of what appeals to you...okay it won't let me post a link..so google sweet aquatics or any aquatic plant site and look at the plants and read more about them

Remember you need at least 80+% of the floor planted in stem plants with soil based tanks to start, some can be removed later as the tank matures.

ok what other plants do you recomend i plan to have two amazon swords at the back two marimo moss balls in the front and a rock in the middle what other plants can i have round the rock

No, you don't need CO2
Yes, stem plants that you plant in the soil
the stem plant is what will halp make the water safe for the fish while the soil is starting its emersed life, it can get toxic during this time and you will need to make daily to weekly water changes until the soil is stable and the stem plants start to actively grow and this can take a week for the plants to start to actively grow and 1-2 months for the soil to start its emersed life.
Once planted and the water clears it is safe to add the fish as long as you make the needed water changes until the tank is stable.

thanks do you mean have many stem plants in? i was looking on theplanted tank website and whats co2 and do i need it? i was planning to plant the tank and add the fish straight away because the fish was all ready living in the tank before i wasnted to plant it.

Your welcome weluvbettas, the bulb sounds fine, make sure you have plenty of stem plants in the soil based tank before you put any fish in it and monitor the water and the fish itself for changes.
It is hard to say if the plants are safe or not without know what kind they are, but most are safe IME-rinse well before use.
Good luck...

I think the plants are just pond weed. oh i forgot to to tell you they were outside for 2 weeks and inside for 1 week are they safe to put in. oh and im getting a desklamp today for my nano tank im getting a 6500k watts bulb i think thats strong anothe and im getting soil on thursday so it should be set up on friday! thanks for all your help! one day i hope to have as much knowlegde on fish as you
