I have a D. filiformis that I purchased locally last year, and one that came as a hitchhiker on a NASC auction item last year and have noticed a curious difference between the two plants. On the purchased plant, the flower buds are coiled, while the hitchhiker has a 180 degree curve with the buds hanging straight down. The hitchhiker also started its flower stalk a few days earlier, while the purchased plant is now growing a second stalk.
It got me wondering if the plants could be identified based on flower stalk growth habits and what other characteristics certain varieties might show other than simply color and size.
