Best Flowers To Grow In Newfoundland Labrador
These flowers are proven winners for our unique climate. They tolerate damp conditions, short sunlight hours, and sudden temperature drops. Below is a breakdown of each top performer.
Hardy Perennials That Return Every Year
Perennials are the backbone of a low-maintenance garden here. They come back stronger each season without replanting.
1. Lupines (Lupinus Polyphyllus)
Lupines are practically the unofficial flower of Newfoundland. You see them growing wild along roadsides in every color from purple to pink. They love cool weather and poor soil. Plant them in full sun and they will self-seed freely.

- Height: 2 to 4 feet
- Soil: Sandy or rocky, well-drained
- Tip: Cut back spent blooms to encourage a second flush
2. Sea Thrift (Armeria Maritima)

- Bloom time: May to July
- Height: 6 to 12 inches
- Soil: Sandy, poor, well-drained
- Tip: Divide every 3 years to keep it vigourous

Annuals That Bloom All Season
Annuals give you instant color and bloom non-stop until frost. They need replanting each year but offer the longest show.

Bulbs For Early Spring Color
Bulbs are the first to bloom after winter, often pushing through snow. Plant them in fall for a welcome spring surprise.

How To Prepare Your Garden For Success
Getting the soil right is half the battle. Newfoundland soil is often acidic and low in organic matter. Here is a step-by-step plan.
- Test your soil pH. Most flowers prefer pH 6.0 to 7.0. Add lime if it is too acidic.
- Amend with compost or well-rotted manure. This improves drainage and fertility.
- Raise beds if your soil stays wet. Many flowers rot in soggy ground.
- Mulch with bark or straw to keep roots cool and suppress weeds.
- Water deeply but less often. Frequent shallow watering encourages weak roots.
- Protect from wind with fences, hedges, or windbreak cloth.
Seasonal Care Tips For Newfoundland Gardens
Each season brings its own tasks. Follow this calendar to keep your flowers healthy.
Spring (April to May)
- Remove winter mulch gradually as weather warms.
- Plant pansies and hardy annuals after soil thaws.
- Divide perennials like iris and sea thrift.
- Apply a slow-release fertilizer to established beds.
Summer (June to August)
- Deadhead spent flowers to encourage more blooms.
- Water during dry spells, especially for containers.
- Watch for slugs and snails. Use beer traps or diatomaceous earth.
- Stake tall plants like delphiniums and lupines.
Fall (September to October)
- Plant spring-blooming bulbs before the ground freezes.
- Cut back dead foliage of perennials after frost.
- Add a layer of mulch to protect roots over winter.
- Clean up fallen leaves to prevent disease.
Winter (November to March)
- Protect tender plants with burlap or frost cloth.
- Check stored bulbs and tubers for rot.
- Plan next year’s garden and order seeds early.
- Brush heavy snow off evergreen branches to prevent breakage.
Common Mistakes To Avoid
Even experienced gardeners make errors in this climate. Here are pitfalls to skip.
- Planting too early. Wait until soil is workable and frost risk is low.
- Overwatering. Wet soil plus cool weather equals root rot.
- Ignoring wind. Wind desiccates leaves and breaks stems.
- Choosing tender plants. Stick to hardy varieties suited to Zone 3-5.
- Forgetting to harden off seedlings. Acclimate indoor plants slowly over a week.
- Using too much fertilizer. Excess nitrogen produces leaves, not flowers.
