Phlox are my absolutely favourite plants, Brian, so have quite a few.
Think we're fortunate in where we live.
This and adjacent towns have lots of garden centres, so I'm usually able to buy phlox, in season, (usually) in flower.
Find a particular garden centre may have a good variety of phlox one year and less the next.
Also find what's available tends to change from year to year, new cultivars continually appearing.
For instance, I saw lots of the pink and white pinwheel 'Peppermint Twist' in one garden centre a bit over five years ago and haven't seen any elsewhere since.
Assuming though that they can be ordered on-line.
I find 'Peppermint Twist' to be a particularly useful cultivar, especially for it's robust growth.
So far this year, I've only seen 'Glamour Girl' (new?), 'Starfire' and 'David's Lavender' (I'd only read about the latter).
I also have the advantage of being retired!
I just have a very small retirement perennial gardening business to distract me from our own small garden.
