Hi luvs!!
I've grown these:
syriaca for many years. It is a thug, so beware. Fragrant though, and loads of bloom.
Incarnata, Swamp, white flowering, has twice now only lived for 2-3 years, then sudden death. Two locations but both on the moist cooler side of the house.
curassavica, Tropical, does well here in my warmest beds, and also self sowed a bit from there this spring- only been growing this about two years.
