Phlox paniculata 'Shockwave' was originally planted in the ULW02. It reverted while in ULW02, losing its variegated leaves and, as best we can tell, reverted back to 'David's Lavender'. We have not seen anything to indicate that it has mutated or has otherwise become a new cultivar. 

Additionally, this planting was moved from the ULW02 to LLW13 in the winter or spring of 2021 to make room for the Salvia Display in ULW02.
