Why do some plants take longer to become harvestable?

My lemon tree seems to take the longest to grow, and become harvestable. I planted it around the same time as the other plants. Why is this? It is still not harvestable.

I'm not sure

Maybe some of these post or some of the people in this thread will know better

Personally, I notice that if I plant the plants at the same time they seem to all have a similar schedule, but outside of that I just tend the garden. I've never really thought about it much more outside of that.

Some plants take longer than others because that's the way the game developers designed them. Lemons take much longer than most other plants, although there are a few that take even longer.
