The tree of orange. This tree didn't go much taller and maximum 10 feet height gain. It yields fruit in January - March ( in my territory) and one tree can give around 300-500 Kg fruit each year.
We have huge verity in which differ in size and shape to each other. But ripe in same time and weather.
It requires dry soil and cold weather. Moisturiser soil and hot may not suit and definitely any fruit which not grow on that part always expensive like we have pineapple, strawberries and coconut costly fruit.
One thing I learned that I think is cool is that the name for the color "orange" was derived from the name of the fruit (orange), and not the other way around.
