Prince Edward Island’s sandy, acidic soil and coastal winds call for shrubs with salt tolerance and a preference for well-drained ground. Finding the best shrubs to grow in Prince Edward Island means choosing plants that can handle these tough conditions while still looking great. You want shrubs that survive the winter winds and bloom reliably each year.
This guide covers the top shrubs for PEI gardens, from flowering options to evergreens. We focus on plants that thrive in Zone 5a to 5b climates, with tips for planting and care. Let’s get started with the best choices for your Island landscape.
Best Shrubs To Grow In Prince Edward Island
These shrubs are proven performers in PEI’s unique environment. They tolerate salt spray, acidic soil, and strong winds. Many also provide food for birds and pollinators.
Native Shrubs For Low-Maintenance Gardens
Native plants are already adapted to local conditions. They require less water, fertilizer, and pest control. Here are top native choices.
- Bayberry (Myrica pensylvanica): This shrub thrives in sandy, acidic soil. It tolerates salt spray and poor fertility. Bayberry grows 5-10 feet tall and wide. It has aromatic leaves and waxy berries that attract birds. It is dioecious, so plant both male and female for berries.
- Red Osier Dogwood (Cornus sericea): Known for its bright red winter stems, this shrub adds color to the landscape. It grows 6-9 feet tall and tolerates wet soil. It also handles salt and wind well. Prune old stems in spring to encourage new growth.
- Sheep Laurel (Kalmia angustifolia): A compact, evergreen shrub that grows 1-3 feet tall. It produces pink flowers in early summer. It prefers acidic, moist soil and partial shade. It is toxic to livestock, so plant away from grazing areas.
- Winterberry (Ilex verticillata): A deciduous holly that produces bright red berries in fall and winter. It needs acidic, moist soil and full sun to part shade. Like bayberry, it requires both male and female plants for berries. It grows 3-12 feet tall depending on variety.
- Sweet Fern (Comptonia peregrina): Not a true fern, but a shrub with fern-like leaves. It grows 2-4 feet tall and spreads by rhizomes. It thrives in poor, sandy, acidic soil and full sun. It has a pleasant scent when crushed.
Flowering Shrubs For Color And Fragrance
These shrubs provide seasonal blooms and often attract pollinators. They need well-drained soil and some wind protection.
- Rhododendron and Azalea: These acid-loving shrubs bloom in spring with vibrant colors. They need partial shade and protection from strong winds. Plant in well-drained, acidic soil with organic matter. Mulch with pine needles or bark. Choose hardy varieties like ‘PJM’ or ‘Nova Zembla’.
- Hydrangea: Several types grow well in PEI. Panicle hydrangeas (Hydrangea paniculata) are most reliable. They tolerate sun and wind better than other types. Varieties like ‘Limelight’ and ‘Little Lime’ bloom on new wood, so they flower even after harsh winters. They need moist, well-drained soil.
- Spirea: Japanese spirea (Spiraea japonica) is tough and reliable. It grows 2-3 feet tall and produces pink or white flowers in summer. It tolerates poor soil and wind. Prune in early spring for best shape. Varieties like ‘Goldflame’ and ‘Little Princess’ are popular.
- Potentilla: Also called shrubby cinquefoil, this shrub blooms from June to frost. Flowers are yellow, white, pink, or orange. It grows 1-4 feet tall and tolerates salt, wind, and poor soil. It needs full sun and well-drained soil. It is very low maintenance.
- Lilac (Syringa): Common lilac (Syringa vulgaris) is hardy and fragrant. It needs full sun and well-drained, neutral to alkaline soil. It can grow 8-15 feet tall. Prune after flowering to maintain shape. Varieties like ‘Miss Kim’ are more compact and mildew-resistant.
Evergreen Shrubs For Year-Round Structure
Evergreens provide winter interest and windbreaks. They need protection from drying winter winds and salt spray.
- Juniper (Juniperus): Many junipers tolerate salt, wind, and poor soil. Creeping junipers (J. horizontalis) are good groundcovers. Upright varieties like ‘Blue Point’ work as screens. They need full sun and well-drained soil. They are very drought-tolerant once established.
- Yew (Taxus): Yews are shade-tolerant evergreens. They need well-drained soil and protection from harsh winds. They can be pruned into shapes or left natural. Varieties like ‘Hicksii’ and ‘Densiformis’ are common. Note: all parts are toxic if ingested.
- Boxwood (Buxus): Boxwood needs sheltered locations and well-drained soil. It can suffer winter burn in exposed sites. Choose hardy varieties like ‘Green Mountain’ or ‘Green Velvet’. Plant in partial shade and protect from salt spray.
- Mugo Pine (Pinus mugo): A compact pine that grows 3-5 feet tall. It tolerates poor soil, wind, and salt. It needs full sun and well-drained soil. It is very low maintenance and works well in rock gardens or borders.
- False Cypress (Chamaecyparis): Varieties like ‘Golden Mop’ or ‘Squarrosa’ add texture. They need moist, acidic, well-drained soil and partial shade. They are less salt-tolerant, so plant away from roads.
Berry-Producing Shrubs For Wildlife
These shrubs provide food for birds and small mammals. Many also have attractive fall color.
- Elderberry (Sambucus canadensis): This native shrub produces clusters of white flowers and dark purple berries. It grows 5-12 feet tall and tolerates wet soil. It needs full sun to part shade. Berries are edible when cooked. Birds love them too.
- Serviceberry (Amelanchier): Also called Juneberry or shadbush. It has white spring flowers, edible berries, and brilliant fall color. It grows 6-20 feet tall depending on species. It tolerates a range of soils and partial shade. Berries are tasty for humans and birds.
- Highbush Cranberry (Viburnum trilobum): Not a true cranberry, but a viburnum with red berries. It has white flowers in spring and red fall foliage. It grows 8-12 feet tall and tolerates moist soil. Berries are edible but tart. They persist into winter for birds.
- Chokeberry (Aronia melanocarpa): Black chokeberry produces white flowers and dark berries. It has excellent red fall color. It grows 3-6 feet tall and tolerates wet soil and salt. Berries are high in antioxidants and attract birds.
How To Plant Shrubs In PEI Soil
Proper planting is key to success. PEI’s sandy soil drains quickly but lacks nutrients. Follow these steps for best results.
- Test your soil pH: Most shrubs prefer pH 5.5-6.5. PEI soil is often acidic. Add lime if needed for shrubs like lilac that prefer neutral soil.
- Choose the right site: Consider sun exposure, wind protection, and drainage. Most shrubs need at least 6 hours of sun daily.
- Dig a wide hole: Make it 2-3 times wider than the root ball but no deeper. The top of the root ball should be level with the soil surface.
- Amend the soil: Mix in compost or peat moss to improve water retention and nutrients. Do not add fertilizer at planting time.
- Water deeply: After planting, water thoroughly. Keep soil moist but not waterlogged for the first year.
- Mulch: Apply 2-4 inches of organic mulch like wood chips or pine needles. Keep mulch away from the stem to prevent rot.
- Protect from wind: Use a windbreak or plant near a fence or building for exposed sites.
Care Tips For Shrubs In Coastal Gardens
Coastal conditions require special care. Salt spray, wind, and sandy soil stress plants. Here’s how to help them thrive.
- Water regularly: Sandy soil dries fast. Water deeply once a week during dry spells. Use soaker hoses or drip irrigation to avoid wetting foliage.
- Fertilize sparingly: Use a slow-release, balanced fertilizer in spring. Avoid high-nitrogen formulas that promote weak growth. Native shrubs often need no fertilizer.
- Prune at the right time: Prune spring-blooming shrubs after flowering. Prune summer-blooming shrubs in late winter or early spring. Remove dead or damaged wood anytime.
- Protect from salt: Rinse foliage with fresh water after storms if possible. Plant salt-tolerant species near roads or oceanfront.
- Winter care: Apply extra mulch around roots in fall. Wrap tender evergreens in burlap to prevent windburn. Water evergreens in late fall before ground freezes.
- Monitor for pests: Common pests include aphids, scale, and spider mites. Use insecticidal soap or horticultural oil as needed. Encourage beneficial insects like ladybugs.
Common Mistakes When Growing Shrubs In PEI
Avoid these errors to keep your shrubs healthy.
- Planting too deep: This is a leading cause of shrub death. The root ball should sit slightly above ground level.
- Overwatering: Sandy soil drains fast, but overwatering can still cause root rot. Water only when top 2 inches of soil are dry.
- Ignoring wind: Exposed sites can desiccate shrubs. Use windbreaks or choose very hardy species.
- Using too much fertilizer: This can burn roots and promote weak growth. Less is more for most shrubs.
- Planting non-hardy species: Check hardiness zones. PEI is mostly Zone 5a to 5b. Some areas are warmer or colder. Choose plants rated for Zone 4 or lower for safety.
- Not mulching: Mulch conserves moisture, moderates soil temperature, and suppresses weeds. It is essential in sandy soil.
