I got this from a nursery in Florida, can't recall the name anymore but it was one of the last two they had...so quite fortunate to have it. It's a much easier grower than some of my other stans..
That is a nice color combination of the S. platycerus. It has a bit of yellow in it that some of the S. napoensis have. What is the fragrance like since you mentioned it smelled good? Nice growing!
