It is one of the many Annums grown as sus/ornamental in Turkey.
The name Sus pepper stands for any kind of chile that grows upwards and hot/very hot.
even though it is named as ornamental, it is not the reason behind planting or using. In fact, many of the Sus peppers are used as extra hot pickles in Turkey.
Also, there is another famous Turkish pepper called, Rosemary pepper= Biberiye Biber. Both Rormeny pepper and Sus are considered ornamental, yet edible and widely used in Turkish cuisine. Any pepper that is planted for pickling called Turşuluk Biber. Therfore, the All Rosemary pepper= Biberiye Biber are sus biber and Turşuluk Biber. But not all sus Biber are Turşuluk.
Here, we have different concept of ornamental pepper as being c.annum, colorful, nasty tasting, and just for the looks. In Turkey, ornamental pepper/Sue is any pepper that is short upwards and may be C.annum or Frutescens.
I hope this helps
