Tulip to be

The focus on this scene turned out strangely. The back leaves of the tulip and the brown strands in the foreground are in focus, but the front leaves are not. Go ahead. Let's hear your theories.

I think it is because the front leaves are actually closer to the camera than the foreground and back leaves. Therefore the focus was on the back leaves distance.
You are looking down rather than straight on - so the front leaves are taller and closer.

I totally agree with Wendy. The tips of the front leaves are closer to the camera since you’re looking down. Interesting question to consider.
