Moses in the Bulrushes, a pretty flower, but...it blooms within the leaves making it difficult to see the flowers. scape size here is 18 inches and I have not noticed any fragrance though it is listed as fragrant. Slow to increase here Zone 5a Canada. Zone 4 US. Would I purchase it knowing what I know now? No. Can't make myself get rid of it, maybe one day.
picture shows blooms within the leaves,
