Name: Rob Lehigh Valley, Pennsylvania (Zone 6b) Ever looking for new plants to kill
Strikingly pretty flower arising from a slender stem in one of my hypertufa troughs. Nothing is clicking, although it looks like some kind of rain lily (which I've not successfully grown before). Zephyranthes, habranthus?
That's a Sabatia, possibly Sabatia kennedyana. I'm not familiar enough with them all to rule out other species as possibilities.
They are so sweet and pretty!
