Yep, that's box. And it does bloom - all non spore bearing plants do, even conifers although nothing most would consider to be flowers - but Buxus flowers are tiny and not very conspicuous except for the delightful light fragrance and the activity of pollinators.

Yep, looks like Buxus.

I just wanted to add that I told the neighbor that there are insignificant flowers or flowers that are tiny that he wouldn't notice. That was before I walked up to view his plants the next morning. He is obviously not a plant person.

I have my certificates of merit in ornamental horticulture from Longwood Gardens . Those classes included four separate botany courses.

I was happy not to smell the boxwood odor from his plants.

Boxwood flowers have a light, pleasant fragrance. Very different from the rank, musty, cat smell of boxwood in the heat of the summer sun!!
