One cross which I made in 1956 was R. carolina x Hugh Dickson. Among the open pollinated seedlings of this cross was one which, during its first year of growth, appeared to be thornless. During its second year, however, a few thorns appeared on the laterals. I then grew 15 open-pollinated seedlings of this rose, one of which proved to be completely thornless. It bears the number 65-626, being seedling number 626 of the year 1965.
