Not a jalapeño.
You know how I have a jalapeño plant in my back yard? It’s decidedly not a jalapeño. When it first started producing fruit, I thought that the peppers were a little short and fat, but they were so small, I thought they might elongate and start to look like jalapeños once they got bigger. However, since the first two have grown substantially, they definitely appear to be some sort of bell pepper. With this suspicion, I went to try and find some confirmation of the early fruits produced by these plants. My baby fruit looks like this:

However, Lisa Joyce on Flickr, has budding jalapeños that look like this:

Yeah… Pretty sure someone switched the labels on my seedling. Somewhere someone is probably surprised to find jalapeños in their bell pepper plant. Now, I wonder if they’re going to stay green or if they’ll turn a pretty color once they’ve fully ripened.
Yep- that’s definitely a green bell pepper plant. I grew green peppers many years ago and they looked just like that. They don’t get very big- less than 1/2 the size of the monsters that you get at the supermarket. They’re tasty too!
Thanks Lisa! I think I’m going to pick one tonight and try it out. I’m not really sure when I should be picking them, but I assume too early is better than too late.
