Wow, lot's of negativity regarding this native American plant. I inadvertently brought a batch of it back with me from Minnesota in a clump of Arisaema triphyllum and some weird vine I have never ever seen that I had dug at my friend Jerry's farm in Pope County. It is so far behaving itself here in Helena but it's also only been in the ground a few months. Man, do the bee's ever appreciate this plant! They go nuts over it. So, I'll take that as a positive. Until it becomes a pest/begins to spread etc. I am not making any judgments on it. It's a beautiful plant to me and I guess that's all that counts. If it does indeed become a pest and I have accidentally introduced a non Montana native, I'll make another comment, but until then, I'll stick with what I said above. Hope I didn't do a boo-boo by bringing it here to the mountains and river/stream valleys of Montana. Doh! - BMc

This has overrun my backyard. In early spring it seems nice because it makes everything nice and green. After it flowers it dies off and looks nasty. Easiest to pull up once full grown, but it's a chore.

My backyard is terraced and filled with lots of boulders so it's next to impossible to eradicate. It overgrows my hyacinths and everything else.

Negative Eleven On Jun 5, 2009, Eleven from Royal Oak, MI (Zone 6a) wrote:

When identifying this native plant on DG, I was warned that it was invasive and difficult to remove. Since the plants had evidently seeded across both sides of my garden, I started removing them. As already noted, they develop an extensive root system. But the plant stems are relatively fragile and break easily... leaving the root system intact and ready to create new plants.

So far, I've had reasonable success in identifying the flowering plants, loosening the soil with a trowel, and digging my hands into the soil to remove the root mass. This is doesn't work for young plants, because they're harder to spot hiding amongst everything else and their root systems are smaller.

This plant is best left to natural woodland areas and out of the garden. As a positive, I'll add that its flowers attract bumble bees. Of course, that's probably how it makes so many seeds!

Hydrophyllum is in my top-5 most HATED plants in my garden...I would love to eradicate this plant entirely from my garden. It self-seeds everywhere...including my gravel driveway, & the aggressive rhizomes will overtake & smother other plants that are nearby. It took me an hour to dig up & slowly remove the waterleaf root was strangling a Peony plant. Certainly not a showy plant, anyway...DON'T GET IT STARTED..!!

Negative Malus2006 On Nov 20, 2006, Malus2006 from Coon Rapids, MN (Zone 4a) wrote:

For a native species, this can be an aggressive weed. IT selfseed at a higher rate and can lie in dormant for a few years. I have to wait until the flowers are done to rip the aboveground section before they go to seed. During the summer, the foliage is ugly as bugs chew the heck out of it. My motto is never plant groundcover that selfseed as they can leap paths and establish themselves near taller plants. The roots are hard to pull out, as it sends down multi "tap" roots that goes deep. And that's in sandy soil! Never include this species among small woodland wildflower gardens unless you uses it in a forest setting that have few plants.

Positive Terry On Jun 14, 2003, Terry from Murfreesboro, TN (Zone 7a) wrote:

The plant's common name "waterleaf" is from the whitish mottling on the foliage; it resembles water stains. Leaves can be cooked and eaten; roots used to make an astringent tea or chewed raw for mouth sores.
