Okay, as much as I love the look and other benefits of live plants...I am not a plant guy. I don't use CO2 and am not about to start; my lighting is usually provided by LED shop lights, and not about to change. My water is hard (300+ ppm) and somewhat alkaline (7.5 or a wee bit higher) and none of that is going to change. My water is my water; plants, like fish, will be chosen to suit the water I have. Some plants do well for me, or at least well enough not to die outright and to expand and spread...although usually not particularly quickly. I'm sure that by the standards of planted tank afishionados, my tanks are a horticultural Auschwitz. I am not even hoping for rich, miraculously fast growth; if a plant stays alive and grows reasonably well, I'm happy. My plants are almost always in pots or trays, and I do make one concession to them: I usually provide a layer of organic potting soil beneath the sand/gravel in the pots. I might... might...even jam a fertilizer stick into a pot occasionally if a plant asks me nicely...but I am just not going to kiss a plant's backside, ever.

I choose plants by buying various species, trying them out, and sticking with whatever survives. For me, that's been Sags, Vals, Swords, Java Moss, and various floaters (Duckweed, Hornwort, Guppy Grass).

I'm moving towards unheated aquarium more and more; I'd like to find a plant species or two that is likely to survive my contemptuous lack of care, and can also do well in temps that will likely top out at seasonal highs around 65F and bottom out in winter at 55F or perhaps down to 50F for the coldest few midwinter weeks. I just want to avoid some of the slow and tedious trial-and-error, and at least start out with plants that might have a chance.

Any suggestions that don't revolve around high-tech lighting/CO2/RO/DI/fertilization? Local aquatic plants appear to require a winter ultra-cold rest period, where they can die off and then come back in spring, so I haven't had much luck with them...or maybe they are just delicate?
 
I was planning on trying Hornwort...not because I thought that it was particularly well-suited to cool, but simply because I am normally throwing it away by the double handful so I have nothing to lose by trying it. :)

Thanks for the reminder about Elodea; it was once a staple in my tanks, which proves that it's bulletproof. I haven't seen it in so long that I am forced to wonder if it's on the ban list; must check.
 
When in Wisconsin I used Myriophylum, Vallisneria carolinia, Sagitteria, Salvinia, Water Lettuce, and Elodea in my cool water (room temp) Urugyayan tanks (many of the same I use here, because they are so temp adaptable).
Even some water lilies (although lack of light intensity, and too much flow became a bit iffy for them). Better suited to a tank near a window that gets full sun.
Some went dormant in winter
Many I collected in local ponds, some were invasive. I also liked Papyrus that grew above the surface of tanks (great nitrate suckers)

I've tried most of those, and had some success with some of them, in my "warmer cool tanks", lol, which usually get down around 60-65F. But my goal now is closer to 50F, so not sure if all of them would survive.

I'm positive that Myriophyllum would withstand those temps...too bad it's one of those plants that turns brown and melts if I so much as look at it. Defitinitely one of my curse plants. But I love the look of that tank full of Papyrus, am definitely going to try that in another tank.

By the way, duanes duanes ...you do know that Papyrus is African in origin, right? Not really biotope-appropriate for your SA tanks...just sayin'...:)

Now i have two anubias barteri in 16 degrees of celsius in coldwater tank.Also i have canadian waterweed and Japanese moss balls .

Beautiful! I have a number of A.barteri doing well; I like them a great deal, but they are so slow growing that I hated the idea of risking them in an experiment. The fact that they don't require substrate is also a huge plus for me. Thanks!

I agree not biotope appropriate, but has been established worldwide, and when I used it, it was mostly in sumps, for its ability to use nitrate, not in a display tank.
The only actual biotope main tank I used it in was a Madagascar tank, where it is native.

My Paratilapia actually spawned, and placed eggs in the stems.
I had to take it out of my Panamanian sump, because it tried to take over the entire 125 gal tank, its now growing in the yard where the water from the washing machine drains, and does amazingly well.

Lol, I'm just yanking your chain about the biotope thing. :)

I'm not one who can talk about that; even when I start a tank with visions of biotopes dancing in my head...it eventually just turns into s Planet Earth biotope...:)

The only way I can maintain an actual biotope is with a single-species unplanted tank; otherwise, I always end up breaking any self-imposed restrictions I started out with.
