"Curious though, have you found certain plants hold up better long-term in flood-prone setups?"
Definitely noticed some plants handle flooding better than others. From experience:
- Swamp milkweed: tough, attracts butterflies, and handles standing water surprisingly well.
- Blue flag iris: looks great, thrives in soggy conditions, and low-maintenance.
- River birch (if you've got space): roots soak up water nicely, plus adds some shade.
Had a client whose yard flooded every spring—these held up solidly year after year. Worth giving them a shot if you haven't already.
"Swamp milkweed: tough, attracts butterflies, and handles standing water surprisingly well."
Seconding swamp milkweed—it's been a lifesaver for me. I planted some last year in the soggiest corner of my yard (seriously, it's practically a pond every spring), and it's thriving like nothing else I've tried. Another one that's worked surprisingly well is Joe-Pye weed. It grows tall, fills space nicely, and pollinators seem to love it...plus it doesn't mind wet feet at all. Worth considering if you're still experimenting.
Swamp milkweed and Joe-Pye weed are solid choices, but have you tried blue flag iris? I put some in a flooded patch last spring, and they're actually thriving. Pretty blooms too, if you're into that sort of thing...
Blue flag iris sounds like a great idea, actually. I've never tried it myself, but I did plant some cardinal flower in a similar spot a couple years back. It did okay at first, but after one particularly heavy flood, it just didn't bounce back. Maybe I should've gone with something tougher...
Speaking of flooding, have you noticed if the blue flag iris helps stabilize the soil at all? I'm always looking for plants that can hold their own and maybe even help prevent erosion. My backyard slopes a bit, and every heavy rain seems to carve out new little channels. Would be nice to find something that looks good and keeps the ground in place.

Funny you mention that—I actually had a client dealing with a similar issue last year. Their backyard had a pretty steep slope, and every heavy rainstorm turned it into a mini Grand Canyon. We ended up planting blue flag iris along with some switchgrass and sedges, and it made a noticeable difference.
Here's what we did step-by-step, if you're curious:
1. First, we added a layer of compost to enrich the soil and help the plants establish quicker.
2. Then we planted the blue flag iris in clusters, spacing them about 12-18 inches apart. They have pretty dense root systems, which is great for holding soil together.
3. Between the iris clusters, we mixed in switchgrass and sedges—both tough as nails and excellent at erosion control.
4. Finally, we mulched lightly around everything to keep moisture in and weeds out.
After about one growing season, the client noticed fewer channels forming after storms. It wasn't a miracle fix, but definitely helped stabilize things. Plus, it looked pretty nice once everything filled in.
Might be worth giving it a shot...just don't expect overnight results. Nature takes its sweet time sometimes.
