Hah! Soil acidity here is not a problem - except in the /other/ direction of too low a PH. In my case I mix in a lot of wood ashes and some lime into my vegetable garden soil.
In your case, if you drink coffee or tea (I drink both) you can save your tea bags and grounds to sprinkle into an small designated area. As it happens, it also drives out snails and slugs which can't abide caffiene, or so I read. Pine needle mulch (and mixing in plenty of rotted compost or peat) can do wonders to make you a nice acidic bed even in very alkaline soil. As long as you continue to dump your coffee and tea leavings there and dress with an acidic mulch like pine needles, I think you could easily achieve a mico-nitche to grow some things your neighbors don't have! I've had great success doing this for some of my native orchids (obtained through Georgia Native Plant Society rescues) when I lived elsewhere. They can be so fussy with their fungal relationships!
I love woodland phlox. I first encountered it on hikes up in the mountains and one cabin we used to live in at around 4,000 feet had it /everywhere/! I brought some of it with me when I moved and I have kept it going ever since. I wish I had thought to collect some foam flower as well.
Here's a link to another post I made that features a photo of one of my shade garden sections that has woodland phlox in bloom right now:
