Newark, OH(Zone 5b)

This is blooming right now in Central Ohio. Right now, as we speak! ;o) It looks a little like something I see in artificial arrangements, but of course they don't label all the silks with the real plant's names! It's about 18" high and the flower clusters are about 1" each.

What is this, please...And is it invasive? I like it, but I want to be sure it isn't something I'll regret transplanting if I bring some home!

Hello I think it's a lady's thumb, Polygonum persicaria
Here's an URl with info on it. Yes it's a weed. :-) Some of my favorite flowers are weeds, some invasive and or noxiose. :-)

Well, phoey! I'm glad to know the botanical name of what I must not transplant to my garden, anyway. ;-) Thanks, you guys!

Before you yank it out consider the spot you're putting it in. There's something to be said for "invasive roadside weeds" - put another way, they're usually pretty carefree and durable.

Now if you're considering placing it next to a prized perennial with a "delicate constitution", that might not be a good idea. But if you have a spot where you can put equally vigorous plants next to each other, they tend to balance themselves.

I guess all I'm saying is the terms "invasive" or "weed" (especially when used together) tend to turn us off, but that's not necessarily a fair characterization - most of the plants in cultivation today at some point were "natives" or "weeds" that were discovered and introduced into gardens.

On the flip side, I purchased tickseed coreopsis from a reputable nursery. The next season, I found it to be an arch enemy that did its best to choke out the coneflowers and shasta daisies I put in the bed with it. So much for feeling confident in nursery selections!

So maybe I am starting to believe that a weed is only a plant in the wrong place :)

We use Persicaria in hanging baskets here. I had one appear in my front garden, brave plant because you really have to be tough in the conditions in that garden ... it lasted one season so they aren't always invasive. One species P bisorta is also used in the making of a traditional pudding (we Brits seem to have eaten everything at one stage or another) which I doubt is baked now called Easter Ledges. Oddly enough I did find a recipe for it sometime ago.

Polygonum bisorta is a medicinal herb and because the roots are shaped in an S (bisorta means twice twisted) it was used to cure snakebite. It resists poisons and has an astringent effect and has been used in many treatments which if no one else has added to the Dbase I'll pop in and fill in.

One mans invasive weed is another mans medical cabinet or meal.

Whew,sure glad someone knew and helped us. Now,I wish I'd have brought it home,another trip perhaps,lol'

I didn't know it was that tough of a "weed" and could have used in my xeriscaping area,so pretty too' Thanks also Baa such interesting facts you share' Especially,the snakebite cure,have many here to cope with and could come in handy' Hopefully,not,lol'

LOL Sis theres a difference between 'was used to cure snakebite' and 'is an effective treatment for snakebite'. Here we have one poisonous snake (almost endemic to the county I live in).

OH' :D

I agree with go_vols, it grows along the road and beach here( we call it knotweed) It is pretty and I let it join with the black-eyed Susan, Queen Anne's Lace,goldenrod etc. I will pick for arrangements,but not put in garden. I do even let that patch of dayflower alone. ;as it makes a nice landing for the jr.birdmen-learning to fly---just not in my flower beds. I am the one that planted Chinese lanterns in the flower bed!!!!!!!!!!!! Now they mix with the others across the road.

In Iowa we also call it Knot Weed. It got out of control in my vegie garden this year. Lots of heat and dry weather and lack of energy on my part has now created a big problem for me. I had it this year where I have never had it before.

Hmmmmmm....Well, seeing how DH and I are not the most diligent come summer heat, perhaps this little pretty would be better left at the roadside for me to admire from time to time. After all, absence makes the heart grow fonder, right? Our whole lot is only 45x140, so it's not like I have a far corner I can plant it in. I might brave it some day, but I'm kinda chicken right now - there's enough to keep DH and I busy with the "cultivated" plants. ;o)

Leave it on the roadside---it's seeds are commonly called 'sticktights' because they cling to everything they touch---your clothes, the dog, etc.
