Gardeners' Notes:

I am in Baton Rouge, LA. Terribly invasive! If this is not already taking over your yard, please don't plant it! It laughs at grass-safe herbicide and eats your flower bed for lunch. There are hundreds of roots, impossible to dig them all up without killing every thing around them.

A couple of loads of wood chips from GRU was contaminated with this weed. Our once-lush & beautiful yard is now a field of Florida Betony. It rooted from everywhere we spread the wood chips & from where the pile sat on the lawn for a couple of days.
This horrific plant has spread to almost every corner of the yard & garden. If anyone wants to come here & dig up the hundreds of thousands of roots, you can eat them all & i'll stop complaining.
Till then, I can only say my yard has been devastated by this plant.

Moist soil and sunshine seems to be about the only thing this plant needs, in order to colonize your yard. Just like dandelions, you can either complain about them, or you can utilize them in your kitchen, eaten raw/fresh, on salads, cooked, or pickled. I'm not a super vegetable lover, and I've tried my share of wild 'edible' vegetables, many of them being pretty bitter. This one, however, is one of the better wild 'veggies' I've tasted. On that first crunch, it bursts with a wet, semi-sweet flavor, probably reminiscent of water chestnut, Jerusalem artichoke, jicama, turnip, or any number of vegetables, according to many. That sweetness apparently is stachyose, a sugar or carb that is similar to inulin, something which is found in Jerusalem artichokes and sweet potatoes, among other vegeta... read more

I would LOVE a few tubers of this. Anyone have it in Tampa?Thanks Please contact me thru [[email protected]]

Very invasive!! Do not plant this in the ground; you will regret it!!
I got some mixed in with a plant I bought & in spite of all my several years of attempting to manually eradicate it, I had not been successful. I rarely use herbicides but have about reached the point of no return with this pest. It has inner twined in my hydrangeas; virtually covered my heucheras; invaded a bed of iris, painted fern & helleborus & it continues to march on toward my daylily beds. It is NOT a nice plant.

I first found Florida Betony growing at a local park. I learned that the roots are edible, so I took a cutting and planted it under my citrus trees. Months later, this one cutting turned into a mat of leaves and flowers that blanketed a patch of dirt devoid of grass. The tubers are tasty, but break easily, and require careful digging. Hoping that consuming the tubers will keep it in check.

I have to agree with Tefoe... and I am looking for a way to get hold of some tubers. I'm a little too far north for them to grow in my yard, but I keep looking in vain. If anyone has any of these weeds, I'll GLADLY take some off your hands!
I'm serious- please contact me.

This spring, I found a large patch while visiting Jacksonville, FL. Tried some tubers, raw, and sauteed in butter. Taste a bit like radishes, without the heat. Will definitely be getting more, and eating more. Am growing them in a planter in Wilson's Mills, NC (zone 7b/ 8a depending on the source). Have tubers for trade!

Fools!! Everyone!

The roots of this awesome plant are very tasty!

Get rid of the crap you spay on your lawn, and go crazy digging up a very nice treat!

Raw right out of the ground, or cooked in a bit of butter! Very nice!

Oh horrible invader... Tender stems snap off above the ever-living tubers, and with the rain it springs right up again... If it would give some flowers we might make peace.

It's difficult to accept that Florida Betony (Stachys floridana) is in the same genus as Lamb's Ear (Stachys byzantina) -- the first is despised and the other prized in most gardens.

To be fair, the Florida Betony does make a pretty pink/purple flower stalk about 4 inches high and can be attractive when grown in thick clusters (which, as noted above, is very easy to do!). It might actually make a nice ornamental plant in a garden where it could be grown as an annual, and either kept in a pot, or left in the ground to be killed by freezing temperatures in winter so that it wouldn't spread.

Florida Betony can be controlled by a thick mulch of pine straw. Some of it will come up through the pine straw, but it will gradually weaken if the top green shoots ar... read more

this is very invasive and very hard to eliminate. Has even grown thru my black landscape fabric.

Florida betony is incredibily invasive, spreading by rhizomes, tubers, and seeds. It grows thick as the hairs on a dog's back. Mow it and it looks like green grass in the winter.

The tuberous roots are edible and sometimes boiled like peanuts. Use as a food is well noted among southeast U.S. Indian tribes and settlers of Florida's early history, as well as today by many nature enthusiasts.
