This has grown to a nice colony in my damp shade garden near hostas, blooming reliably in October and November even as other plants damaged by frost. I only notice fragrance when cut flowers are brought inside, as they warm up. It is a treasure to bloom so late for me.
We discovered this plant growing on our property in Central Texas last October. It bloomed from October until frost. I am not convinced that this plant needs constant moisture, as we have been going through one of the worst droughts in recorded history for this area, and have experienced record heat. My records show we received our last spring rain June 24, 2006 (monthly total 3.70). The next measureable rain event did not happen until Sept 4, 2006 (.06"). The monthly total for Sept, 2006 was 5.80. Maybe the plant is dormant in the summer and begins to grow with the fall rains?
