If it is a clone then it takes its sex from the parent.

I know, but that doesn't answer my question.

But isn't "Juniperus sabina" female gender?

Are you trying to be funny? A normal dioecious species, like a juniper, in the
wild, would have both male and female specimens. It has nothing whatever to do
with grammatical gender. Actually, unless it is irregular, Juniperus has a
masculine ending.
