Maybe I am being a pill but it seems that of late every time someone puts up a picture of a plant for ID everyone insists that the plant is "such and such" cultivar. The one I am seeing the most is pretty much every S. x wriglyeana is being identified as 'Scarlete Belle' when they are in fact not This is just the most prevelant example, there are others out there (the S. purpurea post here recently comes first to mind.)
Now I am sure that everyone probably thinks I am being too sensitive about this but it is important that you not call your plant by a cultivar name unless you are absolutly 200% sure it is that cultivar. *Why is it so important? Because a cultivar is a plant that is recognized for a special trait, that is why it was given the distinction of cultivar status. If you just decid to start calling the wrong plant a cultivar then what you are in effect doing is negating the status of the cultivar.
A prime example of this is the P. 'Sethos'/P. 'Weser' problem we now have, where practically every plant in the U.S. labled P. 'Weser' is actually just a generic P. moranensis x P. ehlersiae hybrid with none of the characteristics of the true P. 'Weser' plant.
Going back to S. x wriglyeana, I have done some research on this matter and AgriStarts (which is primarily the main source for all mass market CPs) has only been producing typical S. x wriglyeana for market. So all those "Cobra Lily" plants you are finding in Target and the plants from PFT are more than likely just plain jane S. x wriglyeana, which is still a very pretty plant, and should only be labled as such. If you read the cultivar description and look at the picture for 'Scarlete Belle' in the CPN you will see that very few of the S. x wriglyeana pictured here actually match up to the description.
So I guess the bottom line I am driving at here is: Before you decide to start calling something a cultivar, be sure beyond a shadow of a doubt that you are correct. If there is any indication that the plant is not the cultivar then call it one is negligent and just plain wrong!
