The Ghostly Jalapeno is a cross of ghost and a Jalapeno. This cross was made by the Dr. Jack Skaggs in Ohio. His cross is the red version. His cross is around generation 8, F8.
This mustard version appeared in my grow in 2020. In color variants it is important to grow another another generation. Which all grew true to color this year.
The mustard color is slightly less heat than the red. This is a superhot that packs a punch with a sweet tart flavor. Hugh yields on these.
