subject pretty well spells it out, while it is a plant it also does have a humanoid form which would theoretically allow it to do so, or rather a druid via wild shape to polymorph and then gear up.
bumping it for the morning crew
Humanoid form in a large flower. Has 4 vines.
I would say no. What gear does she need? Could give her class lvls I suppose.when a druid wildshapes, the new form would need to have appropriate appendage, etc for gear , magic items. Also need someone to put it on you.
i would assume the humanoid form would have hands and fingers, so a ring which requires activation such as a ring of invisibility. it has a body and could put on armor.
why would it need someone to put it on for them? assuming they do in fact have hands it should be able to take care of its own needs of dressing itself if it so chooses.
I would say they could wear anything but boots. Since they fuse into the flower instead of having feet.
