This the first fruit of NZ lemonade grafted 2 summers ago.
After reading this post today, I picked one that was yellow and another that was 70% green.
There were about 4-6 seeds per fruit.
I had high expectations. I like my lemonade very sweet. Unfortunitely, it wasn't that sweet. It taste like a lemon that isn't too sour. The green one did taste better that the yellow one. Hopefully with time it will taste better. It is very prolific.
Also on these trees are Pomona acidless lemons and Hamlin oranges. They are also first fruit and almost ready.
