This plant has perfected the art of taking over garden beds. I've been trying to get rid of this weed for several years now. It shows up all over my yard. Can't stand it.

This invasive plant was inadvertently introduced as a stowaway within shipments of ornamentals from SE Asia to the USA, its presence first noted in Louisiana during the early 1960s. It vaguely resembles Lemon Balm and Nettles in appearance, but is more difficult to control. It forms a taproot and seeds rather quickly, so pull it as soon as you see it. Being vigilant with control reduces the aggravation in successive years.

This plant grows like wild fire in my mulch beads. I hate it!! Be careful if you try to cut it back with a weedeater/weedwacker. I did this two weeks ago and got it on my legs and arms. Within a few days I broke out in a terrible rash that itched like you wouldn't believe.

Arrived in a batch of bad mulch three years ago and I've been yanking it out ever since (grrrrr!) Only thing I've found that really works is starving it of light, i.e. 2-3 inches of mulch wherever it pops up. Each plant will generate hundreds of seeds, so cover or pull BEFORE it generates seed, which is when it's a two-leaf tiny seedling. Grows anywhere, in any soil. My heartfelt sympathy to those who've had the misfortune to get stuck with this horrible little plant. . .

This is NOT a plant to purposely grow. It is a very invasive weed! Apparently, it comes in nursery stock and spreads quickly to where it takes over any beds and disturbed ground and even tries to grow in parts of the lawn. I noticed it a few years ago in a small patch, and now it has spread to beds on three sides of my house and in another bed removed from the house area. I could not id this weed in any of my 5 weed/wildflower books and finally got the Weed ID dept. at Virginia Tech to do so. You can pull out the weeds several times during a summer, and it keeps on returning. Because it grows around good plants, I think it will take some creative application of herbicides, but I'm going to start early next spring when plants are small. Please don't even think of obtaining this plant... read more

Extremely invasive. Location indicates it came in a packet of wildflower seeds sown in the garden by my landlady. The roots of some of the plants growing in sunnier locations have nodules -- they may be nitrogen fixing.

I hate, hate, hate this weed. Took me a long time to get it identified. It is ugly, it is persistent, but it is easy to remove (if you have hours and hours for this task).

Seems to really thrive in moist areas or during rainy season. Doesn't seem to damage nearby plants but I hate it just the same.

At first, I thought these were wildly hardy Lantana seedlings since that annual bed is where I first spotted them. They appeared here a few years ago. After reading the original entry here, I"m guessing mine must have come in the same way: mulch, which I buy in truckloads.

This stuff comes up everywhere! Even after pulling it up by the roots, it comes back. It was apparently introduced into my gardens in mulch, as those are the only places it appears, but it's extremely difficult to eradicate, in my experience. The leaves and stems are hairy, and it sticks to clothing and gardening gloves, hence my own nickname for it - "velcro plant".
