Sounds like some good results to me. Trim that basil plant make sure and leave a few leaves on it, give it some fertilizer and continue to water it.
If it’s in a pot, bring it in and you should have basil all winter - I kept one going for 5 years, and it would still be going, except that I just decided to dump it - it was looking so scraggly. I am still using dried basil from that plant.
It starts making these stacks of flowers - many went brown
Like 6-8 stacked on a branch.
