A new graft cactus (Copiapoa scopa) cultivar ‘edstone’was developed at Cactus Research Institute, Gyeonggi-do A.R.E.S, in 2007. GCP563 and GCP618 were crossed in 2004 and we got 9 seedlings from this combination. After pedigree selection in 2005, one cultivar was finally selected through the test of specific character in 2007 and named as “edstone” “edstone”cultivar has red brown color and round globose shape with 15 ribs and its spines are black. This cultivar is able to produce 26.8 offshoots per plant. ‘edstone’cultivar has higher productivity and more slow growth than Copiapoa scopa cultivar.
