My first experience in hybridization. Ten seeds were sown, only one seedling appeared. I cross-pollinated “Yellow Quirka” (name for croton # 6, 7 in Australia) and “Nervia” #8 or “Eureka” (commercial names in Holland) It had been always dark green with very rare spots and I was about to throw it away. But I liked the leaves’ shape and saved it as I hoped to use it in hybridization in future. Only in 4 years I saw red and dark contrast. I think that leaves will become more narrow and brighter outdoors.
