First make sure its legal to collect plants in your area and then look for your states web-site on native aquatic plants-most states will have one with lots of information......
When I collect native plants to use in the aquarium-its important to properly acclimate them to the florescent lights and QT them before use in the aquarium
I like to use light colored buckets to keep the plants in so that I can view the bottom to remove any aquatic life that I don't want in my aquarium and make daily water changes
Keeping the bucket outside in direct light or light close to the location I collect the plants and move them to lower light areas every couple of days...it usually takes me 10 days or so before I can get them in the house under florescent light.
The bulb-sometimes they grow and sometimes they don't....I have had a 50/50 success with them....You don't want to bury them in the substrate-let them sit on top and check them daily for rot-if they ever become mushy, soft, fuzzy growth or smell bad...toss them.....they can take weeks to months to sprout.
You can also place them in a container of water in a sunny window-sometimes this will help them sprout faster....It also depends on what species of plant it is......
The onion plant....I can't help you with that....never had one.....
