Hi, thank you for the question.

To source plants and seeds for a native wildflower garden to support pollinators, consider the following:

1. **Choose Native Species**: Select wildflower species that are native to your region. This ensures that the plants are well-adapted to the local climate and soil conditions, making them more likely to thrive and provide the necessary resources for native pollinators.

2. **Use Local Seeds**: If possible, opt for seeds that are produced in the same climate as where they will be planted. This increases the chances of the plants being well-adapted to the local conditions.

3. **Diversify Plantings**: Plant a mix of species that bloom at different times of the year to provide continuous floral resources for pollinators throughout much of the year. This includes a range of flower sizes, shapes, and colors to attract various pollinators.

4. **Purchase from Reliable Nurseries**: When buying plants, look for nurseries that specialize in native plant varieties. This can help ensure that the plants are well-suited to the local environment and are of good quality.

5. **Avoid Hybridized Flowers**: Try to avoid planting hybridized flowers, especially "double" flowers, as they may not provide the same benefits to pollinators as native species.

6. **Support Local Seed Banks and Native Plant Societies**: These organizations often have a variety of native plant species available, and they can provide guidance on which plants are best suited for your area.
