I ordered two pistachio trees (one male + one female) over the internet. I have just received them yesterday. Unfortunately, they didn't label them and now I can't find out which one is male/female. Can you please identify them from the photo below?
One of them is shorter and has larger leaves.
The other one is taller and has smaller leaves.
Google doesn't help me very much. I asked the seller and he said that the one in the blue package is female. However, this is my first time shopping from him, so I don't want to be wrongly informed. Can you please confirm the genders of these trees?
