No. In Jain doctrine, pratyek vanaspati has one soul in one body.

If you mean sādhāraṇ vanaspati, then many souls can reside in one body. That is the type of vanaspati described as having shared embodiment.

So, in short:

• Pratyek vanaspati = one soul, one body
• Sādhāraṇ vanaspati = many souls, one body
