<p>Botany is usually a choice under the Biology major sub-category or under Plant Studies. Your very large state universities will likely have such a sub-major & your ivies, but not small public schools or liberal arts schools. Think of something like Purdue or Illinois given that they are farm states. NJ is the garden state & I know Rutgers features Botany, Plant science, forestry, Plant pathology. Also I would check into the George, Alabama, Florida, & Texas public universities.</p>
