Thank you!! And thanks for the tips on photographing an insect in the future! I'm hoping not to see anymore, but if I do I'll put something next to it for scale. This was my very first time ;)

grubs can usually be found in the lawn.. in the grass roots.. if you might care to dig up a small patch to find them.. though i should say.. usually there are dead patches all over the lawn.. because they are eating the roots.. https://duckduckgo.com/?q=grub+lawn+damage&t=ffab&iax=images&ia=images when there is a bad infestation.. the robins start digging around and eating them ... as with any bug..one or a few is never a problem.. its when its one of those 10 year plague events.. and there are millions of them ... and that is when some action needs to be taken... unless yo just want to go all morticia... and like leaf less plants... https://images6.fanpop.com/image/photos/39700000/Morticia-trimming-roses-animated-gif-the-addams-family-1964-39772240-500-367.gif how large is your plague.. if any ken

It could be annual rye grass that got mixed in and is going to seed

It seems to be a cultivar of a panicle hydrangea but with so many compact varieties of them for sale now a days (Bobos, Strawberry Sundae, Little QF, etc.), I would ask for cuttings in order to get/propagate that exact one. It may even be a larger cultivar too but just young, recently planted. Getting a spring cutting would be my goal. Nice shade of pink blooms indeed. Where did you take the picture? Some restaurants lease the location and a landscape company handles the plantings from the land owner.
