Lophophora Williamsii
var. jourdaniana

The famous Lophophora Williamsii var. jourdaniana is known for its incredibly deep pink or magenta flower, often described as red in colour. The trouble with this plant is, the very fact that it is not a true Lophophora but a hybrid with no proven origin. In fact, if any plant with such a label produces viable seed, the person will be given the clue that it is not the known jourdaniana in their collection but something else because seeds from this hybrid are said to be sterile. It has also been my experience having planted seeds from about a dozen different suppliers around the world, that about ninety percent of seeds with the label of "jourdaniana" do not germinate and of those few that do, only a small fraction of a percentage of plants will ever produce the famously bright coloured flower, as shown in one of my luckier plantings here below. Another factor that further questions the actualitity of this plant, is the fact that many of my Lophophora Diffusa var. fricii plants, as well as those with the label of decipiens, also produce the exact same coloured flower along with identical body structures as the one shown here below. The final question that arrises about this variation is, its title, indicating it to be of the Williamsii family, in turn containing mescaline as its primary alkaloid. As I have mentioned, all plants that I have successfully grown with the label of jourdaniana, look exactly like any member of the Lophophora Diffusa var. fricii varieties I have grown, which indicates that it is more closely related to the Diffusa family if anything.

Interestingly enough, Lophophora Williamsii var. jourdaniana is said to not take pollen from any of the Diffusa or Williamsii family of plants and apparently, the only person said to have successfully crossed this plant was a Russian botanist by the name of Serge Batov. So how on earth can one possibly come up with such a plant? Expereimentation is the answer, for not a single grower including myself will give up that secret.

There is much discrepancy as to what a proper cross would be to produce this variety known as Lophophora Williamsii var. jourdaniana and many suggest crossing a typical Williamsii plant with a brightly coloured flowering fricii variety, (you can try this yourself but you will find it does not work). For those with the greatest of interest, I can offer a clue. As mentioned on my desrciption page, Lophophora Williamsii has been successfully fertilized by Ariocarpus Fissuratus, L.Diffusa, Mammillaria Bocasana, M.Zeilmanniana, Strombcactus Disciformis, Turbinicarpus Pseudomacrochele, Astrophytum Asterias, and Epithelantha Micromeris. Once you complete your expereiments you will understand why the price of seeds for this variety are so high!!

Most research indicates that unlike all other forms of Lophophora available, the jourdaniana variety actually has small spines on its ariolas. That's right... Lophophora Williamsii var. jourdaniana is supposed to have spines thoughout its entire life, unlike that of the Williamsii or Diffusa families, which only have soft spines as tiny seedlings that are eventualy replaced by small tufts of hair or wool as we prefer to say. These tiny put sharp spines can be seen on the image here below as well as a the amazing close up shot shown at the bottom of the page taken by my good friend David R.
