And would like to point out not all gardeners have access to the Harry Potter Crystal Ball, so that they’ll know in May how their garden is going to look in September. Even the Macon County Master Gardeners get blindsided some years by global warming and Japanese beetles and whatnot, and the various commemorative rose, peony, lilac, etc. gardens don’t look as good as they’re supposed to on the desired date. So all the Macon County Master Gardeners can do is give an estimated date, and say, “Hold your reception in the Scovill Rose Garden on June 15th”, but if the weather doesn’t cooperate, the display won’t, either.
So just because she told you in May that September would be the best time for you to come take its picture doesn’t mean she’s an idiotic bitch–it just means that normally September would be the best time for you to come take its picture. It’s not her fault the weather didn’t cooperate this year.
And, I might add, September is normally when most gardens look their best, because by that time the crabgrass and other annual weeds have shot their wad, you’ve caught up to them, and there are a number of splashy late perennials like asters that are eminently photogenic, and if that’s what she’s got in her garden, then yeah, “September” is when I’d tell you to show up, too.
