Last year when i was looking at this plant the homeowner came out: I’m pretty sure he was concerned about what I was doing, but he didn’t ask. He just came out to see what was going on. I asked him what this plant was but he didn’t have an answer for me. I’m now in a Facebook group that identifies plants and, so far, there was only one they never managed to ID, and that one (not my image, actually) didn’t have enough of the plant to determine what it was. This year the plant was in full bloom and I took a number of photos with my iPhone. (Sadly I don’t have any with my good camera, but oh well!) Below are four of those images. I think the plant is gorgeous. It is an Australian shrub.
Prostanthera ovalifolia ‘Variegata’ (I through IV), 4.8.2020
