The character can converse, in very rudimentary terms, with all sorts of plants and plantlike creatures (including fungi, molds, and plantlike monsters). The character automatically exercises limited control over normal plants. Plantlike creatures can negate the control effect with a Will save.
The spell does not enable plants to uproot themselves and move about, but it does allow them to move their branches, stems, and leaves.
The plants can duplicate the effect of an entangle spell or free creatures trapped by that spell.
