Q.Is this a type of basil as well?
I just began growing basil for the first time. My sweet basil in one container has sprouted and already starting to form broad leaves. In my holy basil container, I only have two sprouts so far. One is looking to be broad leaved as well (right) but the other one has long thin leaves (left). Is this also a type of basil? I got the seed packets from a business, so I’m not sure if the seeds just got a stray or what. Just curious.

Those are some tiny sprouts and I would hate to give you the wrong answer. Here's what I would do: either pinch one of the little leaves or clip a tiny piece and pinch between your fingers. If it smells like basil...you'll know. Here is an article that lists several types of basil:
