| History | This improved hybrid holly, 'RutHol 1', was developed by Dr. John M. Ruter, renowned plant breeder and researcher at the University of Georgia. Open pollinated seed was collected from the seed (female) parent, Ilex crenata 'Sky Pencil' (unpatented). Two distinctly different male hollies were growing in the vicinity of the female plant: I. crenata 'Glass' (unpatented) and an unnamed plant of I. maximowicziana (unpatented), both of which have an overlapping period of anthesis with 'Sky Pencil'. The collected seed was cultivated and 'RutHol1' was subsequently selected from this cultivated area. Ilex 'RutHol1' appears to be intermediate to I. crenata and I. maximowicziana, confirming that an unnamed plant of I. maximowicziana is the pollen (male) parent. The original 'RutHol1' plant is growing in Tifton, Georgia. |
