Do Clerodendrum quadriloculare and gardenias have invasive roots? I want to plant them for a privacy fence outside my fenced pool.

If a plant's water needs are met, they will not become root invasive. Plants that have high water needs have a higher chance of becoming root invasive because it is harder to meet their water needs. But even plants that do not have high water needs can become root invasive if they do not get the water they need.
