Variegated KASEN. Regular Kasen mutated and produced KASEN. Special. This kind of mutation happens time to time and many of great variegated bean leaf started from one stripe on leaf. It is very exciting to see how it changes in future.
KASEN looks similar to ISECHABO but have wider stem. When this variety produce tiger stripe, it would be called KASEN-NO-TORA. There is one with stripe in Japan but have never seen it for myself. Cute bean leaf variety. Easy to grow.
