But since Bboy said that sand cherries are actually a variety of purpleleaf plum, does that mean that in this case, the term "cherry" is really just slang and there isn't any significant difference between sand cherries and flowering plums? Pineresin, do those photos of cherry blossoms not apply to sand cherries (in terms of how many blooms you should expect to see in each cluster)?

My best guess would be Coffea arabica? The plant that they make coffee from. It looks like mine does. I bought mine last year and it has more than doubled in size, but is still fairly young. Nowhere near blooming size yet.

Ligustrum.?

Multiple different kinds of smaller growing forsythias are on the general market now. The days of the kinds that produce a 10 ft. fountain of growth being pretty much all there is are over. Apart from it cutting part of the bloom off shearing forsythias not situated in formal layouts and settings is a bad idea because it makes them out of context, same as shearing any other kind of shrub or tree not part of a geometric design. Low maintenance mantra is dominant in the market for new landscaping here these days. At the same time formal shearing of existing informal plantings on both commercial and residential properties has become pandemic. The way I see it companies doing this are mowing the lawns and mowing everything else as well. In keeping with this a decades old informal garden across the street from me has been getting maintenance sheared for some years now by company current owners hired. Before that previous occupants had some of that done also, but more here and there - resulting for instance in what should now be a Stewartia pseudocamellia of some height and presence being instead a tubby, flat-topped tuft of whips like a giant fez. And so on, throughout the property. Perhaps an assumption that formal shearing is a normal maintenance routine practiced in all settings is a lot of what is behind many requests for new installations being low maintenance.
