There,s no way of telling what they are realy and as far as the sex i can,t see as the picys a bit blured.
But at the base of each branch you will get two prongs , this is nothing to go by .
What you need to look for is pairs of very fine white hairs for a female.
If you see balls like in pairs or bunches of grapes it a boy .
That is a very good price for bluberry if they are.
