Is this a single stem or bush?

[Noah]

Can you tell whether this is a single stem rose or a bush? All I know is that’s it’s supposed to be a black rose.

And when should I move it to a bigger pot. It’s currently in about a 4 inch pot

It's a single stem, but you can make it bushy by pinching off the top bit. When you do that, more branches will grow on the sides and after that you can still punch the NEW top bits of the new shoots and the plant will get bushier still and more flowers and fruit / seeds will develop. The pot looks OK for the time being. Do feed the plant though.

Is that actually a rose? It looks more like a young pepper plant to me. I have never seen that leaf formation on a rose.

At what height should I start pinching the top off to make it into a bush?

Looks like rose seed to me I bought them online. Never grown roses before though.

I thought rose leaves were always serrated.

Noah, that is not a rose. Silent is probably right--a pepper.
Do I understand that your bought it as a seed on-line? Roses normally do not grow from seed, but from cuttings.
Whatever you have, let it grow and we'll all find out!

Yes, please!! I love a good mystery!

No, not a rose, Agree with SR: probably a pepper! How did I manage to miss the word rose

 

[Noah]

Awe well I guess only one way to find out lol. I’ll update you guys to see what it was but I’m pretty sure it was a rose i planted unless I got it mixed up. Are these roses?

 

[alp]

NO, not roses at all!

This is a typical leaf of a rose

And the stem

Rose in a pot.

I remember when I was much younger there was a contest for growing a perfect black rose since none existed. Does anyone else remember the details of this? To the best of my knowledge there still is no black rose except in Photoshop.

Noah, whatever that is, it is not a rose! It is looking less like a pepper, but I'm not familiar with many peppers. Please keep us updated--this is fascinating!

The plant in your first post is definitely not a rose and a true black rose doesn't exist. There's a possibility that the plants in this post are Petunias and some do produce black flowers.
