Viburnum are big shrubs with textured leaves, flat umbles, or rounded clusters of blooms and berries for birds, these larger-scale adaptable versions of the hardy native have a wide range of form, interest, and benefit for your landscape!

Stop and smell more than just the Roses with these easy-care ornamental Shrubs! Perfume your world with these and many more scented flowers available at Nature Hills. You will enjoy seeing … and smelling your landscape!

Keep Those Flowers Fragrant Longer

  • Avoid pesticides and chemical fertilizers - they harm pollinators and take away from the shrub's fragrance
  • Use drip irrigation - Avoid getting the flowers wet if able, so water at the roots. This also keeps the leaves clean and disease-free
  • Time of day and weather - Flowers tend to smell better in the morning before the sun and heat of the day evaporate the volatile oils. Sun evaporates the volatile oils into the air quickly.
  • Keep your cut flowers smelling great longer by trimming the stems each day. Keep your vases and water clean with daily changes, use flower food, and keep your blooms out of drafts/heating vents and full sun

Any one of these shrubs will add their beauty and fragrance to your home and garden! Turn your landscape into a paradise for more than just the eyes! Add a new dimension to your garden experience and feel the hectic world get whisked away!

Happy Planting!

Frequently Asked Questions

Which fragrant flowering hedge shrubs grow best in my USDA hardiness zone?

The best fragrant flowering hedge shrubs for your zone depend on your specific USDA hardiness zone, but many popular options like Lilacs thrive in zones 3-7, while Butterfly Bush performs well in zones 5-9, and Sweet Mock Orange adapts across zones 4-8. Viburnums are among the most zone-flexible choices, with various species covering zones 2-9, making them a reliable pick for nearly any garden. Visit naturehills.com and use the plant search filters to sort fragrant flowering shrubs by your specific hardiness zone for the most accurate recommendations for your region.

How far apart should I plant ornamental hedge shrubs to grow a full, dense hedge?

For most ornamental hedge shrubs, planting 2 to 3 feet apart on center will produce a full, dense hedge, though larger species like viburnum or lilac may need 4 to 5 feet of spacing to fill in properly without overcrowding. Check the mature spread listed for your specific variety, then plant at roughly half to two-thirds of that distance to encourage the shrubs to knit together over time. For the fastest privacy results, plant in early spring or fall when cooler temperatures reduce transplant stress and roots can establish before summer heat arrives.

How much sun or shade do fragrant hedge shrubs need to bloom their best?

Most fragrant flowering shrubs perform best in full sun, meaning at least 6 hours of direct sunlight per day, which encourages the most prolific blooming and the strongest scent production. Some varieties, like certain viburnums, can tolerate partial shade with 3 to 6 hours of sun, but flowering will be reduced and fragrance less intense. To get the most out of your fragrant hedge, choose a planting site with morning sun and good air circulation, and avoid locations where buildings or large trees cast heavy afternoon shade.

What kind of soil and drainage do ornamental hedge shrubs need to thrive?

Most ornamental hedge shrubs thrive in well-drained, moderately fertile soil with a pH between 6.0 and 7.0. Waterlogged or compacted soil is one of the most common causes of poor performance and root rot in flowering shrubs. Before planting, amend heavy clay soils with compost or aged bark to improve drainage, and consider raised berms in areas with standing water. Test your soil before planting and adjust pH as needed to give your shrubs the best possible start.

When should I prune flowering hedge shrubs so I do not cut off next season's blooms?

The best time to prune most flowering hedge shrubs depends on when they bloom. Spring-blooming shrubs like lilacs and forsythia set their flower buds on old wood from the previous season, so prune them within a few weeks immediately after they finish flowering. Summer-blooming shrubs like butterfly bush bloom on new wood, meaning they can be pruned in late winter or early spring before new growth begins. Always identify whether your shrub blooms on old or new wood first, then schedule your pruning accordingly to protect next season's flower buds.

Which fragrant hedge shrubs bloom on old wood versus new wood, and why does that change how I prune them?

Shrubs like lilacs and mock orange bloom on old wood, meaning they set their flower buds the previous season, so pruning them in fall or early spring removes those buds and sacrifices your bloom. Roses and butterfly bush, by contrast, bloom on new wood produced in the current season, so cutting them back hard in late winter or early spring actually encourages more vigorous flowering. As a general rule, prune old-wood bloomers within two to three weeks immediately after flowering finishes, giving them the full growing season to set next year's buds.

How tall and wide will these fragrant hedge shrubs grow at full maturity?

The size at maturity varies considerably depending on which fragrant shrub you choose, as these plants can range from compact 3 to 4 foot specimens to large multi-stemmed shrubs reaching 10 to 15 feet tall and wide. Lilacs, for example, can reach 8 to 15 feet tall, while other fragrant options stay much more manageable at 4 to 6 feet. Always check the specific variety's mature dimensions before planting, and space your shrubs accordingly to allow for proper air circulation and natural form. Visit the individual plant pages on naturehills.com for exact height and spread measurements so you can plan your hedge spacing and placement with confidence.

Which of these shrubs work best as a tall privacy screen versus a lower decorative border hedge?

For a tall privacy screen reaching 8 to 15 feet, look to flowering shrubs like Lilac (Syringa) or Viburnum, which naturally grow upright and dense enough to block sightlines while delivering impressive fragrance. For a lower decorative border hedge in the 3 to 6 foot range, compact flowering selections like Dwarf Korean Lilac or fragrant Deutzia work beautifully without requiring heavy pruning to stay tidy. Browse the mature height details on each plant's product page at naturehills.com to match the right shrub to your specific screening or border needs, and plan your planting for fall or early spring to give roots the best establishment before their first flowering season.

How can I encourage stronger fragrance from my flowering hedge shrubs throughout the season?

To maximize fragrance from your flowering hedge shrubs, plant them in full sun since most scented shrubs like lilacs and viburnums produce the strongest scent when receiving at least 6 hours of direct sunlight daily. Apply a balanced slow-release fertilizer in early spring and avoid excess nitrogen, which pushes leafy growth at the expense of blooms and fragrance. Deadhead spent flowers promptly to encourage repeat bloomers to push out a second flush, and give plants a light shaping immediately after their main bloom period so you never accidentally cut off next season's flower buds. For the most intense fragrance experience, visit your hedge on warm, still mornings when essential oils are most concentrated, and position seating areas nearby to make the most of the scent.

How do I care for flowering hedge shrubs after they finish blooming to keep them healthy and full?

After flowering hedge shrubs finish blooming, prune them within two to four weeks of the last flower fading to avoid cutting off next year's buds, which form on new growth through summer. Apply a balanced slow-release fertilizer in early spring before bloom and again after flowering to support vigorous regrowth and root development. Water deeply once or twice per week during dry spells, aiming for moisture to reach 12 to 18 inches deep, and add a 2 to 3 inch layer of mulch around the base to retain moisture and suppress weeds. Deadhead spent blooms promptly, remove any dead or crossing branches, and your shrubs will reward you with a fuller, healthier framework for next season.
