Recent events have led me to believe that the original plant labeled D. filiformis 'Florida Giant' that I received from a local nursery a few years ago was mislabeled by that nursery. The plants you received from me are all from seed of that original plant and its offspring as I have never had any other form of filiformis other than that one original plant and its progeny. In speaking with the nursery, the plant I got from them is either a hybrid of typical D. filiformis and filiformis 'Florida Giant' or a typical filifromis.
Please accept my humble apology for the mislabeling of these plants I sent to you all. I am now calling what I have simply D. filiformis, unknown variety.
