Did You Know?

More than 96% of the plants we offer are straight species, which are crucial for creating a thriving ecosystem. Unlike cultivars or hybrids, which are often selected for specific aesthetic traits, straight species have coevolved with local insects and animals for thousands of years, creating a vital, interdependent relationship.

The Importance of Straight Species

1. A Vital Food Source: Straight species have the specific chemical makeup that native insects, particularly caterpillars, rely on to survive. These caterpillars are the primary food source for many nesting birds. Without the right plants, the entire food web can collapse.

2. Supporting Genetic Diversity: Planting straight species, helps ensure a diverse gene pool, ensuring that plant communities remain resilient to environmental changes like disease and drought. Since cultivated varieties are usually cloned, they lack genetic diversity, thereby weakening the ecosystem's long-term health.

3. Building a Complete Ecosystem: A garden with straight species isn't just a collection of plants; it's a living ecosystem. You are providing the essential resources that support a complex web of life, from the smallest insect to the largest predator.
