Short, cold-hardy submerged plants?
Posted 14 May 2014 - 12:40 AM
But now the new liner is on hand and I'm itching to get started.
As it's a pool in both shape and spirit, i want to retain the swimming volume. I'd like to find more than just dwarf Vallisneria, which I'm uncertain is even hardy in my area, to plant in the shallow end. Does anyone happen to be aware of any other native, zone 5-6 hardy species that don't grow high off the substrate (Anything 18" or less)? I'm willing to give longshots a try.
I'm having a lot of difficulty identifying even potential plants.

Let's see... Iowa is just shy of the range distribution of echinodorus tenellus. It's sort of like a shorter vallisneria, very grass and pursuant to your request.
There is an echinodorus found in Iowa, and it appears to be a cute sword plant type thing. Echinodorus rostratus, found using https://plants.usda.gov using the stateSearch function. All the rest of these plants are going to be ones I'm picking from that list. It lists all the plants in your state, and I'm eyeballing for common aquatic genus. So, anyway, echinodorus rostratus:
Also on that list, I see myriophyllum pinnatum. That's one of my favorite plants.
A lot of the najas are native to Iowa, too, but I dunno, I just don't like the look of najas gracillima, myself.
Najas flexilis is cool.
Najas guadalupensis is commonly available in the aquarium trade:
I dunno, I don't really like it. You see it in pictures sometimes looking nice like this:
but in real life, guadalupensis looks like this:
You've got some ludwigias in Iowa, like ludwigia palustris.
There's a bacopa, bacopa rotundifolia, although I've personally never had much good growth with any bacopas. My bacopa monnieri grew about as fast as a rock grew. It was more a decoration than a plant.
But yeah, all those are found in Iowa so they'd likely overwinter well for you. Well, maybe not the echinodorus tenellus, but here's its range distribution:
Here's the link I got those names from. Sort by state. Unfortunately you can't yet sort by underwater growth or not. https://plants.usda.gov

My trouble was in finding a resource identifying plants that overwinter here. You have helped me tremendously.
I am technically zone 5, but as it's a protected site, in full sun, and right along the south side of my house I'm sure I can get by with zone 6. You have given me a tremendous resource,
I can't thank you enough!

List of books worth looking into if free to find aquatic plants to then search for on the list of your state's native species:
- Wetland Plants of the Northern Great Plains: A complete guide to the wetland and aquatic plants of North and South Dakota, Nebraska, eastern Montana and eastern Wyoming by Steve W Chadde
- Aquatic Plants of the Upper Midwest: a photographic field guide to our underwater forests by Paul M. Skawinski
- A Field Guide to the National Wetland Plant List: Wetland Ratings for Plants of the United States by Steve W Chadde
- Wetland Plants of Wisconsin: A complete guide to the wetland and aquatic plants of the Badger state by Steve W Chadde
- Wetland Plants of Michigan by Steve W Chadde
- Field Guide to the Aquatic Plants of Lake George by Eugene C. Ogden
- A Field Guide to Common Aquatic Plants of Pennsylvania by Dana Rizzo
- Aquatic and Wetland Plants of Northeastern North America : Volume 1 and Volume 2 by Garrett E. Crow; C. Barre Hellquist
- A Field Guide to the Common Wetland Plants of Western Washington & Northwestern Oregon by Sarah S. Cooke
- A Great Lakes Wetland Flora by Steve W. Chadde
I wish there was a comprehensive guide to Iowa's aquatic plants, but if there is one I'm not seeing it. Maybe you could make a list, given the usda.gov list and learning more about which species are aquatic. That would be helpful. You could post it here, like, "Iowa's aquatic plants" and then a big list.
