Are all species of juniper fine to brew with?

[Bosh]

Noticed some large juniper bushes in the park. Was thinking of throwing in an oz or so of juniper berries into the boil for a piney IPA. I'd go full sahti and harvest the branches except I don't think people would appreciate me hacking a backpack full of branches off of their ornamental bushes.

Only question is I have not a clue what kind of juniper it is. Are all kinds of juniper fine to brew with or should I figure out what kind it is before proceeding?

Watch out some species are too bitter or poisonous

Many thanks. Making poisonous beer would be a bad thing.
