Holly (Ilex) is a beloved shrub that has year-round interest. There are many varieties of holly that grow to be quite tall, forming a solid barrier in the yard. "Hollies are low-maintenance too, so once they’re established, they offer plenty of beauty with little hassle," says Putnam.

Forsythia is one of the earliest bloomers in the garden, arriving in late winter to early spring. "Forsythia shrubs feature vibrant yellow bell-shaped flowers that appear before leaves emerge on the branches," says Kelly Funk, president for Jackson & Perkins. "The shrubs are fast-growing and have an upright arching habit."

A fast-growing, woody evergreen, thuga has dense foliage characterized by its conical shape. "Thuja is good for privacy because it is a fast-growing, evergreen shrub that produces dense foliage that can provide privacy year-round," says Funk. "Prune in early spring to maintain desired height and shape."

Butterfly bush (Buddleia) is a deciduous flowering shrub that produces colorful blooms and attractive foliage. "The plant features long, arching branches covered with clusters of small, fragrant flowers," says Funk. "The flowers come in various colors, including purple, pink, white, and yellow, attracting butterflies, bees, and other pollinators." It's a dense, fast grower that should be regularly pruned in late winter or spring to ensure it maintains its shape.

Weigela has arched branches that are covered in red and pink blooms from late spring to early summer. The foliage is typically deep green, burgundy, or purple and can be variegated. "Due to its dense foliage and upright growth, weigela is ideal for privacy screening," says Funk. "Pruning after flowering maintains shape and encourages future blooms."

If you're looking for a low-maintenance shrub option, consider barberry. It's commonly grown in landscapes for its durability and adaptability to poor soils. "Varieties with reddish or golden foliage add an intriguing element to the landscape," says Damon Abdi of the Hammond Research Station at Louisiana State University's agricultural center. While it's a great privacy shrub, keep in mind that it may be considered invasive in some zones, so do your research before planting.

Loropetalum boasts red, burgundy, or green foliage and flowers in a range of colors, from pinks and reds to purples and whites, says Abdi. It's an insect- and disease-resistant plant that will beautifully accent the other plants in your yard.

Pittosporum has evergreen leaves in tight whorls that form at the top of the branches, creating a pleasant texture in the garden, says Abdi. It provides white flower clusters that stand out against the shrub's foliage.

For a fragrant option, sweet olive (Osmanthus fragrans) has pleasant-smelling small flowers that bloom during fall, winter, and spring, adding subtle interest to the landscape. "The blooms are small and not super showy, but they definitely have an appealing scent," says Abdi.

Azaleas are known for their vibrant pink blooms, which add vibrant color to the garden. While not all azalea varieties are good for privacy, some can grow to be up to 10 feet tall and look beautiful as a living fence.
