Plant Upright Blue Juniper for Year-round Interest

Virtues: Silvery blue juniper is an easy option for adding year-long color that complements the nearby plants in each season. Tall selections such as ‘Wichita Blue’ and ‘Blue Heaven’ (pictured) provide a strong vertical element in the shrub border. They can also embellish an entryway or multiple plants can be used to create an evergreen hedge or windbreak. They also offer resistance to deer, extreme winter hardiness and good drought tolerance.
