Hedges serve many purposes in the landscape. They can be used for privacy, security, as a windbreak, or simply because they look quaint. In U.S. Continue reading for tips on choosing hedges for zone 6.
A hedge is a densely planted row or wall made of living plants. The plants in these living walls can be evergreen or deciduous, depending on your specific needs or preferences. Tall plants and evergreens are oftentimes used as windbreaks, noise barriers, and privacy hedges.
Cold winter winds are usually what our yards or homes need protection from, so evergreens work best for this purpose too. Shrubs with thorns or sharp, spiky foliage make excellent hedges where home security is a concern. Other times hedges are planted simply for their appearance or to separate different areas of the landscape.
Hedges can be perfectly shaped, squared, or rounded with hedge trimmers or garden shears. They can also be left alone to grow in their own natural habit. This, too, is based on your own preference and landscape style. Hedges made from native, fruit producing shrubs can also double as a safe haven for birds to browse or nest in.
Whatever purpose you have in mind for a hedge, there are plenty of shrubs to choose from. Below are some of the most common zone 6 hedge plants and the types of hedge they can be used for.

1. Red Twig Dogwood
Dogwoods are some of the best trees and shrubs around (yes, they are considered both trees and shrubs, depending on the variety). There are seriously hundreds to choose from, and red twig dogwood is one of the best (look for the botanical name Cornus sericea). You can grow it as a small tree or as a shrub, pruning it as you see fit. The best thing about this shrub is that is has bright red stems, so it looks fantastic in winter when there’s not very much other color.
2. Crape Myrtle
Bees adore it, butterflies love it, and it’s a staple in the south. It’s crape myrtle (Lagerstromia). This shrub (which can grow so tall that some mistake it for a tree) is a true sign of spring with its beautiful pink flowers. It can tolerate less-than-perfect soil conditions, and it’s common to see rows of these growing in public gardens or bordering long driveways. Sorry northern gardeners, but it might be off limits to you. If you’re right on the edge of its hardiness zone, you can try offering it protection over the winter, and you just might get it to grow!
The harbinger of spring: this is how gardeners often refer to forsythia (Forsythia × intermedia). When it’s really early in spring and not much else is blooming, the gorgeous golden flowers emerge and brighten up an entire landscape. This shrub really is one of the first things to flower, and it sure does make an impact. You can find gobs of forsythia options out there, including dwarf varieties only reaching a few feet tall to border forsythia, which spreads and is used for borders, hedges, and screening. After the initial bloom, they mostly fade away and are forgotten, but they can still offer a solid swath of green for the rest of the growing season.
The world of hydrangeas is HUGE! You can find hundreds and hundreds to choose from, and the botanical names can get a bit confusing. To make things simple, let’s focus on one of the most popular, the bigleaf hydrangea (look for Hydrangea macrophylla). You can find two main groups, including those with globe-shaped flowers (called mopheads) and flattened flower heads (called lacecaps). Both are beautiful, and once you get them established, they grow for years! Don’t lose patience if you don’t get yours going right away. Sometimes you just need to find the right location in your garden.
The hardest thing to do is to figure out whether juniper is a tree or a shrub. The short answer is that it’s both! You’ve probably seen junipers growing before, most of which fall under the botanical name Juniperus chinensis. This evergreen is extremely versatile, and it’s very popular for people who want something to offer a little privacy in the backyard. All junipers are reliable and fairly maintenance-free, though, so you can plant them without worrying. Plus, nearly all produce blue little berries for the birds!
Yews are one of the longest-living evergreens, and they are a staple in many backyards. You’ve probably seen a yew, even if you didn’t know what it was. While the entire yew family is huge, let’s focus on Taxus x media. This is a hybrid group made up of English yews, which are great ornamentals, mixed with Japanese yews, which can survive harsh winters. All are good options for getting some year-round green added to your yard, but this group of hybrids is particularly known for being relatively disease-free and easy to care for.
Here’s another one—is it a tree? Is it a shrub? Ask two different gardeners and you’ll get two different answers. And they’d both be right. Think about what’s most important to you. Is it fall color? Is it offering food for birds? Is it spring flowers? All serviceberries do this, but some have higher marks than others. For a smaller serviceberry, look for the botanical name Amelanchier alnifolia. For a tree, look for botanical names Amelanchier arborea and Amelanchier canadensis. Once you figure out your #1 priority and you know your space needs, then set out to talk to someone at your local garden center to find a serviceberry that fits those needs.
8. Rose of Sharon
Don’t be fooled by the name on this one. It’s not actually in the rose family at all. Instead, it’s related to hibiscus, which generally have tropical-looking flowers. Look for the botanical name Hibiscus syriacus. Still, gardeners definitely grow it for its blooms, which last all summer. The blooms look a bit like hollyhock and the shrub is very forgiving overall. In fact, some gardeners love the challenge of training a rose of Sharon, pruning it to look like a miniature tree.
Spirea can come in many shapes and sizes. For instance, there’s a kind of spirea called bridal wreath (Spirea vanhouttei) that can get up to 10 feet tall and a whopping 20 feet wide! Because there are so many different types, this is one where it’s really important to read labels when you’re shopping at the garden center. Look at the size listed before you buy. All spireas make great hiding spots and nesting locations for birds, and they are known for producing beautiful spring and summer flowers, too.
Viburnums (botanical name is also Viburnum) can vary a lot in size and shape, but they do share a few key important traits. For instance, all viburnums have year-round appeal with flowers in spring, great foliage in summer, nice color in fall, and berries that last through winter. Birders and gardeners like viburnum equally because of the wide appeal it has with birds. If you only have space for a few shrubs in your backyard, definitely make room for a viburnum. There are seriously hundreds to choose from, so you’re bound to find one that works in your space. Plus, many on the market today are native cultivars—definitely a bonus!
Every garden needs those shrubs they can absolutely count on 100% and feel the success of easy gardening. Now, you can plan your next shrub purchase with the confidence of knowing you’re not going to fail. There are 91 more ideas in Plants You Can’t Kill that will make gardening a breeze.
Look for the book on Amazon or at your local bookstore for even more suggestions on plants you can’t kill. The book also includes recommendations for perennials, trees, annuals, grasses, houseplants, herbs, and veggies.

Here are a few of the most popular fast-growing hedge varieties found in the United States.
A fast-growing deciduous hedge, with beautiful foliage colors in the autumn. Watch it burst into hues of orange, red, and yellow during the fall.
This variety is a very cold hardy variety and survives in temperatures down to as low as -40ºF. The multi-stemmed characteristics of this hedge make it an excellent choice for privacy in the garden.
This variety grows quickly into an enormous hedge that’s ideal for creating a private sanctuary in your yard. Some of the fastest-growing hedges in this variety gain more than 3-feet in a growing season.
The hedge is very heat tolerant, making it the ideal choice for coastal areas and arid regions of the U.S, where temperatures run high. Gardeners will have to prune two to three times per year, and it’s a drought-resistant plant that grows in almost any soil type.
The English Laurel is tolerant of salt in the air, and it’s naturally resistant to pests like deer. It’s the ideal choice for large areas where the homeowner needs plenty of privacy.
Also known as “Skip Laurels,” the Schip Laurel hedge is another fast-growing variety, growing tall and thin. This hedge can tolerate full sun or full shade, making it one of the most resilient hedges available.
The Schip Laurel also grows readily in a variety of soil types, and it’s not got any aversion to salt or smog in the air. The Schip Laurel does well in colder environments up to USDA Zone 6. We like the Schip Laurel for covering fences in the yard, bringing a natural aesthetic to the perimeter.
This stunning hedge is both fast-growing and easy on the eyes. It’s the ideal variety of coastal regions and areas of the United States with warmer climates. The spreading habit of the Portuguese Laurel makes it easy to maintain, and with annual pruning, it quickly forms a dense.
The Portuguese Laurel is very drought-resistant once it establishes a root system, and it does well in coastal regions, as salt and smog in the air are not an issue for this hedge. The hedge grows well in any soil type, and it’s also resistant to pests like deer.
The Portuguese Laurel suits planting in the shade or the sun, but for best results, we recommend full sun for optimal growth.
The thickness of this hedge makes it one of the best choices for a fast-growing privacy hedge.
The privet is gaining popularity with homeowners across the United States. However, those homeowners seeking a formal-looking hedge for landscaping purposes might find the privet the attractive option for a hedgerow.
The dense growth of the hedge makes it an ideal choice for privacy, and the spreading also makes it easy for shaping. The privet grows at a pace of 12 to 25-inches a year. If gardeners use fertilizer when planting and during the early springtime, then they can expect rapid growth rates.
The Leylandii has to be the second most popular hedge after the Laurel. It’s becoming popular with homeowners in the United States due to it requiring little maintenance during the growing season, and it provides a dense hedge that’s ideal for increasing the privacy in your yard.
The Leylandii can grow as much as 35-inches per year, making it one of the fastest-growing hedges available.
