I think you are right on the first two. The pepper may be one that is grown as an ornamental plant. Sometimes the peppers are a beautiful color.

I believe the last one is a weed. It had such pretty leaves I let it grow once to be sure.

Ditto on first two. Third is deffinatly not weed,saw tooth isn't deep enough. Let it grow because you can never tell,it might smoke better than weed. (;

Hmmm, seems there is a difference in 'weed' and 'a weed' ... :-)

Hee hee heee,you caught it too rose,,,,,,,,,,,,,,,or maybe the question was actually phrased as intended.

Omg no i meant the weed that you want to get rid off not the one people smoke

How to find out? I dont wanna chop off something that has been growing for years

English sucks. I don't know how people learn it as a secound language. If you don't see the same plant growing in other places nearby it's likly a cultivated plant. If it's growing in the alley and behind the shed it's probably a weed. If it's a voliteer plant from seed of a cultivated plant and growing where it's not welcome that's a weed as well. Then you have wildflowers like Indian Blanket and Blue Bonnet that are nothing but weeds most of the season that happen to have pretty flowers briefly. If they are in the way chop them down. The worst weeds I've dealt with was Trumpet Vine and Bamboo but some folks plant the stuff and water it. Hey,I once smoked grapevine when I was a kid,I wonder if anyone ever tried smoking a Bamboo stalk? LOL

I, the King of the weeds (not "the" weed), think that the third one looks like penta pente. Maybe a white ruellia?

Good guess Omar 'King of Weeds", but it's not pentapete. Not sure what a white ruellia looks like, or a purple one for that matter since I don't have it growing here. Going out to look around tomorrow and see if I can find the weed that it looks like to satisfy my own curiosity. I searched, but couldn't find the post from several years ago where I asked about a similar looking plant that turned out to be a weed.

Carrie, I'm laughing. Reminds me of when I was about six and a neighborhood kid told me the little red berries on a Chile Pequín tasted good. Ouch -- it was hot! I haven't tried another one since!

Fine, Queen of Pentapetes. You might be right. I know that it is not a purple ruellia because they have a purple tinge at the base of each internode, but maybe it could be a white or pink tall ruellia.

So the third one is a weed or not?

It's hard to tell whether it's a weed or not. For now watch to see if it flowers. Then we'll know for sure.

well even though it flowers, if there is no fruit, I will kill it. If the tree does not have fruit, it has no right to be in my garden.

The third plant looks to me like it might be a Goldenrod, from the leaves. I guess they technically are a weed, as a lot of people don't specifically plant them in gardens, but they have nice yellow flower blooms in September and October.

The third plant is not a fruit bearing plant. It is a little early for it to be goldenrod, but it could be. I would pull up that third one for sure. It is a weed. I share the same feelings about planting in the garden. I only grow things that we eat.
