Why grow flowers from seed in Canada?
Growing flowers from seed costs a fraction of buying bedding plants from garden centres and gives you access to a wider variety of cultivars. PPS curates a selection of flower seeds suited to Canadian growing conditions — heat-loving annuals for summer beds, cold-hardy perennials that survive Canadian winters, and pollinator-friendly wildflower mixes.
Best flowers for Canadian gardens
Sunflowers, zinnias, marigolds and cosmos thrive in Canadian summers with their long warm days. Cold-hardy perennials (echinacea, black-eyed Susan, daylilies) return year after year. Native wildflower mixes support pollinators (bees, butterflies, hummingbirds) and require minimal maintenance once established. For shorter Canadian growing seasons, choose varieties that bloom 60-90 days from seed.
Pollinator gardens for Canadian growers
Native pollinators (bees, butterflies, hummingbirds) are declining across Canada. Planting pollinator-friendly flowers supports local ecosystems and benefits vegetable and fruit gardens nearby. Bee balm, milkweed, echinacea, sunflowers and native wildflower mixes attract pollinators. Avoid neonicotinoid-treated seeds, which can harm bees.
How to grow flower seeds successfully
Most annual flowers can be direct-sown after last frost. Start tender annuals (marigolds, zinnias) indoors 4-6 weeks earlier for earlier blooms. Perennials and wildflowers often need cold stratification (2-4 weeks in the refrigerator) before germination. Provide 6+ hours of sun, well-draining soil, and consistent moisture during establishment.
Annual vs perennial flowers
Annuals (zinnias, sunflowers, cosmos) bloom prolifically all summer then die at frost — replant every year. Perennials (echinacea, daylilies, black-eyed Susan) bloom shorter but return year after year, reducing long-term work. Combine both for continuous blooms and reduced replanting effort.
Frequently asked questions
When should I plant flower seeds in Canada?
Annuals: direct-sow after last frost, or start indoors 4-6 weeks earlier. Perennials and wildflowers: plant in fall (with stratification) or early spring after stratifying in the refrigerator.
Which flowers attract pollinators?
Bee balm, milkweed, echinacea, sunflowers, zinnias, cosmos, and native wildflower mixes. Combine spring, summer and fall bloomers for season-long support.
Are PPS flower seeds organic?
Many varieties in our flower catalog are heirloom and/or organic. Check individual product listings. We do not sell neonicotinoid-treated seeds.
How do I create a pollinator garden?
Plant a mix of native wildflowers, perennials with overlapping bloom times, and avoid pesticides. Include shallow water sources and shelter (bare soil, brush piles).
Can flowers grow in containers?
Yes. Most annuals and dwarf perennial varieties thrive in containers. Use a quality potting mix and water more frequently than in-ground gardens.
