The climate here along the Central Gulf Coast of Florida is in the humid subtropical category. As such, any number of exotic species thrive here with little or no assistance.
I am familiar with several species of night blooming cereus from the desert southwest, so it was pleasant to see these blooming in my neighbor’s yard this past June.
I have since been able to add a few cuttings of these to my yard since someone placed their unwanted trimmings out by the curb. They are thriving right now and I look forward to their nighttime show next year!
