Butterfly Treats: How to Start Native Seeds

Cold Stratification, or exposure to cold temperatures, is required by many native seeds. As in nature, winter cold followed by warm spring signals to seeds that it’s time to shed its hard shell and start the germination process.

My Low Tech Process for Germinating & Growing Native Perennials

🌱 Why Native Plants Matter

Native plants are plants that have grown on Long Island forever — long before lawns, roads, or houses were here. And they do a lot more than just look nice.

🐝 They Help Wildlife Survive

Butterflies, bees, birds, and other animals grew up alongside native plants. They depend on them for food, shelter, and places to raise their young.
Many non-native plants might look pretty, but they don’t actually feed local wildlife.

No native plants = no pollinators = fewer birds and less food for everyone.

💧 They’re Built for Long Island

Native plants are already adapted to our sandy soil, salty air, and changing weather. That means:

  • Less watering

  • No chemical fertilizers

  • Fewer pesticides

They’re tough, low-maintenance, and don’t need much help to thrive.

🌎 They Protect Our Water and Soil

Native plants have deep roots that:

  • Soak up rainwater

  • Reduce flooding and runoff

  • Keep pollution out of our bays and groundwater

Healthy plants = cleaner water for people and wildlife.

🌼 They Boost Biodiversity

When you plant natives, you don’t just get one plant — you get an entire mini-ecosystem.
More plants → more insects → more birds → healthier nature overall.

Even small gardens, schoolyards, or curbside plantings can make a big difference.

💚 They Help Fight Climate Change

Native plants store carbon, cool the air, and don’t rely on gas-powered lawn equipment or chemicals. That makes them part of the solution, not the problem.

🌱 Rewilding Is About Bringing Nature Back

ReWild believes our yards, schools, and public spaces can do more than just sit there.
By planting native plants, we turn everyday spaces into places that support life — for wildlife and for people.

You don’t need acres of land. Every native plant counts.
