Though not all varieties of holly are hardy in New Hampshire, many varieties of holly shrubs are available to choose from that will add beauty to your New Hampshire landscape.  Be sure to check your hardiness zone before purchasing hollies or any other plant materials for your landscape to ensure that the plants you are considering are suited for climatic conditions in your area. 

Deciduous or evergreen varieties of holly shrubs are available in both tree and shrub forms.  Smaller holly varieties can be as short as 3 feet at maturity while other varieties can grow up to 30 feet tall, so care must be taken in selecting holly shrubs to ensure that they will eventually grow to the desired size for the intended planting area.  Berry color varies and can be white, yellow, black or red.  To locate hollies in New Hampshire, please visit LGYP.com.

A deciduous, native holly you might want to consider planting in your New Hampshire landscape is Black Alder, also know as Common Winterberry, Coralberry, or Michigan Holly (Ilex verticillata native).  This variety grows best in part-shade or full sun and will reach a height of 5 to 10 feet.  Soil should be moist.  Common Winterberry Holly has white flowers in the fall and red berries that will linger on the plant into early winter.  Its leaves are dark green in summer and turn yellow and purple in fall.  Like many holly varieties, Common Winterberry Holly readily attracts birds, so hollies are an excellent shrub choice for New Hampshire wildlife-loving gardeners.
