Although this is an awkward grower with wiry long canes that leap out ten feet in all the wrong directions, it is a noteworthy footnote in Moore's development of the yellow and orange toned mini-mosses that followed in the subsequent forty years.
When used in breeding, Orange Moss is a difficult plant at best; it won't set seed with foreign pollen, and the offspring are often uniformly dreadful. (Ralph insisted that he never got viable seed of any kind from it, although in 2010 I germinated three open pollinated seeds from it) Indeed, it must have been that one lucky seedling in 500 that showed any promise. It is a testament to Moore that he was able to coerce this unruly once-bloomer to sire anything of value at all.
By the way, pollen will be available upon request, for those brave enough to make use of it.
