Prostanthera rotundifolia is a widespread shrub in Australia that occurs naturally from inland Queensland south through New South Wales, , Victoria and South Australia down to Tasmania. The name for the genus is from the Greek word 'prostheke' meaning an "appendix" and 'anthera' meaning an "anther" in reference to the appendages on the stamens and the specific epithet means round leaves.

We also will relate observations made about it as it grows in our nursery gardens and other gardens we have visited, as well how the crops have performed in containers in our nursery field. We will also incorporate comments that we receive from others and we welcome hearing from anyone with additional information, particularly if they can share any cultural information that would aid others in growing it.
