Today’s special is our Foster #2 Hybrid Holly. These are shipped in 2.5 inch containers and are 6 to 10 inches tall for only $4.03 each.
Foster holly is a chance hybrid that occurred between a narrow-leafed form of the Dahoon Holly (I. cassine var. angustifolia) as the female parent and American Holly (I. opaca) as the daddy in the union. The trees grow 25 to 30 feet tall with a spread of 6 to 8 feet, giving them a narrow, conical form. The bright evergreen leaves are 2 inches long and elongated with one to three small, nonthreatening spines on each side of the leaf margin near the tip.
Foster holly is an excellent plant for planting near an entry or off the corner of the house to provide vertical accent. Like most plants with this strikingly conical form, it can be grown as a free-standing specimen or massed together. It also makes an excellent tall screen or can be sheared into a hedge. If used in mass plantings, the length of the mass should be at least one and a half times longer than the plants will be allowed to grow tall to create visual harmony.
Like most hollies, Foster holly does best in a reasonably good garden soil where it can receive some water during dry periods. The soil pH should be on the acid side. While best in full sun, it will do well in medium shade.
Foster holly can be sheared as needed to keep it full or left to its own devices. If plants ever get too large, they can be stubbed back severely in the spring just before new growth starts and will regrow quickly to a compact but smaller size. Zones 6 to 9.
