Evergreen Conifers For Zone 9
Hedges are often used as borders or property demarcation lines, protecting yards or gardens. Besides lasting year-round, evergreen hedges have several advantages over deciduous ones. They offer year-round protection, but are also easier to grow than deciduous hedges, requiring less pruning or training. They also require less water and less composting.
Evergreen hedges tend to give an excellent impression of the property, presenting nicely when pruned into attractive shapes. While they do create a boundary, they also retain a green, natural look that a fence cannot provide.
Many different types of evergreen plants can make up evergreen hedges. For maximum resilience to disease and insects, it’s a good idea to use more than one variety.
A partial list of the varieties that make excellent privacy hedges includes: Holly (Ilex), Firethorn (Pyracantha coccinea), Privet (Ligustrum vulgare), Boxwood (Buxus), Yew (Taxus baccata), Green Giant Hybrid Arborvitae (Thuja plicata x standishii), Leyland Cyprus (Cupressus x leylandii) and Heavenly Bamboo (Nandina domestic). While these vary in growth rates from the slow-growing Holly to the fast-growing Leyland Cyprus, all make beautiful hedges that with a little care, will last for years.
