I don't believe that my region is "Humid Subtropical Climate." I believe that begins about 200 miles south of my front door.
I also disagree with this: "Winters are mild with precipitation from mid-latitude cyclones. Seasonality is moderate." I suppose "mild" is relative. To someone from North Dakota (or South Dakota, for that matter), a Delaware winter would indeed be mild. But, we average 20" of snow per winter, and we have a reasonably good possibility of getting into single digits a few nights each year, too. Hardly what I call mild, but again, it might be mild to some.
Lastly, it mentioned the lack of a "dry season" here. I will say that as long as I can remember, most (not all) summers are accompanied by a somewhat long period of dry weather when virtually no rain falls. This can last 3 to 6 weeks. Typically, it runs from early July to halfway through August. But again, not every summer sees this, but I would say most do. As far as the seriousness of our dry spells, I have seen as many or more plants in the region succumb to heat + drought than to winter cold over my lifetime.
