tl, if you want weeds, those sound like them to me...wherever they come from, lol. Yep, easy to grow...
OP, if you're worried about snails etc., you can treat plants when you get them...but not all treatments are very plant (or maybe animal) safe. That's why I quit pretreating plants, I killed lots of plants but hopefully not too many fish or inverts...but I rarely buy from shops anymore.
I also live in a big city area & have at least 2 lfs (ish) that sell "tissue culture plants". Not everyone has those options or an awesome plant club.
Some amateur sellers have only a couple plants you may want...& some are very stingy with a 2 inch piece of stem plant, healthy or not so much...with several shipping fees. You may try looking online for a seller that has all or most plants you'd like to buy...But ask us first, sometimes the pretty pics & descriptions won't actually grow well in your tank...I've killed many plants over the years
...& grown some well too
