Ilex x ‘Doctor Kassab’
Rooted cuttings are 4-8″ in height. A hybrid Chinese holly, the Dr. Kassab holly was introduced by noted gardener Dr. Joseph Kassab in the years following his return from WWII. The result of cross pollination between a Chinese Holly (Ilex cornuta) and a Perny Holly (Ilex pernyi) in Dr. Kassab’s Philadelphia garden, the hybrid has soft dark green leaves that are not prickly like American hollies. All hollies are dioecious – meaning that male and female flowers are borne on separate plants. The Dr. Kassab holly is female. As a female, the holly requires the presence of a male pollinator for berry production. Almost any male that flowers in the springtime will do. In addition to its tight clusters of red berries, the Dr. Kassab holly excels as a living fence and makes an excellent landscape specimen. The holly has a slow to moderate growth rate and grows 15 to 20 feet tall and 8 to 10 feet wide with a pyramidal shape. Best for USDA Hardiness Zones 7 through 9, the evergreen holly thrives in full sun and is tolerant of most soils. More planting instruction can also be found at boydnursery.net/planting/.
