options do I have and what is the best way to handle this situation?
Some options include:
(1) trying to interest the local prosecutor's office in charging her with criminal trespass and/or criminal mischief,
(2) making it more difficult for her to enter your property again in future by installing more fences, hedges, or a security system (all subject to your local zoning code of course),
(3) fixing any damage she did to the plants by following the recommendations for "rejuvenation pruning of rose of sharon" that you find when you google that on the web, and otherwise ignoring the whole incident.
The best way to handle the situation depends on how your neighbor is likely to react to whatever you are considering doing. Since I've never met your neighbor, I'm less qualified to opine on that than you are. All I can do is encourage you to do your best to guess how she will perceive what you do and what she is likely to do in response. Peacemaking is usually the best in the long term, except when dealing with out-and-out bullies.
