A regionally tailored native wildflower mix for Ontario and Quebec, selected to feed bees and other pollinators from late spring into fall. The blend pairs early bloomers with summer and fall flowers, so nectar and pollen are available across the whole growing season. These seed bombs are best used in sunny to partly sunny locations with well-drained soil, along garden edges, meadows, naturalized lawn areas, roadside plantings and restoration patches. Each seed bomb combines native seeds with clay, worm castings and biochar to protect the seeds until conditions are right for germination.
Included species
Wild Lupine (Lupinus perennis)
Butterfly Milkweed (Asclepias tuberosa)
Lance Leaf Coreopsis (Coreopsis lanceolata)
New England Aster (Symphyotrichum novae-angliae)
Wild Bergamot (Monarda fistulosa)
Evening Primrose (Oenothera biennis)
Purple Coneflower (Echinacea purpurea)
Planting notes
When: Late-fall dormant planting allows natural winter conditions to help seeds that need cold, moist stratification. Spring planting may produce staggered emergence; some seeds may wait until after another winter. Follow your mix’s instructions.
Where: Bare or lightly loosened soil with as little competing vegetation as possible. Place seed bombs on exposed soil for good contact.
How: Place each seed bomb on the soil and if desired press it in so it sits snug against the ground. Leave about 30 cm (1 ft) between seed bombs. Water gently as needed and keep the area moist during germination and early establishment without waterlogging.
What to expect: Native wildflowers take patience. Many establish roots in their first year and bloom more fully in later seasons, and some seeds need a species-specific period of cold, moist conditions before germinating.
Pack contents: Six seed bombs, with a suggested planting area of approximately 6 square feet. Coverage is an estimate, not guaranteed flower cover.

Common Milkweed, for example, is the monarch caterpillar’s food plant. Best used in sunny to partly sunny locations along garden edges, meadows, roadside plantings and restoration patches. Each seed bomb packs native seeds into a clay carrier with worm castings to protect them until conditions are right for germination.

Planting notes
When: Fall is ideal, just before the ground freezes. Spring planting works too once temperatures are cool.
Where: Bare or lightly loosened soil with as little competing vegetation as possible. Seed bombs can be set directly on the soil or even on snow in late fall.
How: Place each seed bomb on the soil and if desired press it in so it sits snug against the ground. Leave about 30 cm (1 ft) between seed bombs. Water lightly if rain isn’t expected.
What to expect: Native wildflowers take patience. Many establish roots in their first year and bloom more fully in later seasons, and some seeds wait for a freeze-thaw cycle before germinating.
Pack contents: Six seed bombs, covering about approx. 6 square feet.

Planting and care
Prepare exposed soil and manage competing vegetation. Place seed bombs on the surface and press gently for contact, spacing them about 30 cm (1 ft) apart. Water gently as needed and keep the area moist during germination and early establishment without waterlogging.
Many species need or benefit from cold, moist stratification. Late-fall dormant planting lets winter provide natural seasonal conditions. Spring planting may lead to staggered emergence, with some seeds waiting until after another winter. Follow the mix instructions and our How to Plant & FAQs guide.
Native perennial plantings take time: roots and leaves may develop before fuller flowering in later seasons. Seed bombs support a planting plan; they do not replace invasive-plant removal, site preparation or follow-up care.
Make your own native wildflower seed bombs with a hands-on activity for home gardens, family time and learning together. This retail DIY kit makes up to 30 seed bombs, depending on the size you make.
What’s inside: seed packets, a premixed planting medium with clay, worm castings and biochar, a measuring spoon, and instructions. The updated pink box contains the same kit materials.
Plant your finished seed bombs in a prepared patch suited to the mix and your region. Many native species need or benefit from cold, moist stratification, so follow the planting instructions and allow time for seasonal germination.
