Abstract

A new and distinct rose plant is provided which is particularly well suited for service as a rootstock for a rose scion cultivar. More specifically, when so used the scion cultivar exhibits a propensity to yield an increase in biomass and the promotion of faster bud release when compared to the results achieved when the scion cultivar is grown on its own roots or on a standard rootstock, such as ‘Natal Briar’. Both higher production rates combined with improved quality in the scion variety are facilitated. The new rose plant displays an upright growth habit with vigorous growth. Small single light pink changing to near white cup-shaped blossoms are formed having five generally heart-shaped petals. Yellow/orange reproductive organs are prominently displayed at the centers of the blossoms. Medium green leaflets with finely serrated margins and a matte upper surface are displayed.
