Are mock orange hedges poisonous to humans in anyway?

Mock orange hedges, primarily belonging to the genus Philadelphus, are not considered poisonous to humans. They are generally safe and non-toxic, making them suitable for gardens and landscapes. However, while the plant itself is not harmful, it's always a good practice to avoid ingesting any non-food plant material. If ingested in large quantities, any plant can potentially cause mild gastrointestinal upset.
