Low-growing hedges can serve as attractive living borders in any garden, yard or landscape. The best plants for a small hedge are hardy shrubs with bushy, compact structures. Such small hedge shrubs include glossy abelia, shrubby Saint-John's-wort and Korean boxwood.
Glossy abelia (Abelia grandiflora) is a hybrid shrub native to China that typically reaches a mature height of 3 to 5 feet. It bears small, glossy green leaves and fragrant whitish-pink flowers. In growing zones 8 and 9, it tends to be evergreen, while in zones 6 and 7, it loses its leaves in winter. Glossy abelia grows in either full sun or partial shade and tolerates most soil types.
Shrubby Saint-John's-wort (Hypericum prolificum) is a deciduous shrub hardy in zones 3 to 8. It reaches a maximum height of 4 feet. This low-maintenance plant produces small, linear dark green leaves and showy golden flowers that bloom throughout the summer.
Korean boxwood (Buxus microphylla koreana) grows to a height of 4 feet. It is hardy in zones 5 to 9. In the winter, its leaves may turn yellowish-brown or purple yet remain on the bush. This shrub enjoys full sun or partial shade and may be damaged by severe winds.
