Flowers for Butterflies

What are the best flower seeds for butterflies?
Butterflies bring the garden to life with motion and beauty. Sadly, with the ongoing disappearance of wild land in our modern world, many butterflies are endangered and at risk of going extinct. The best way to protect them is to provide a safe habitat for them in your own organic garden.
How to Attract Butterflies
Adult butterflies are attracted to brightly colored flowers with shallow nectar tubes. They like to feed in the sun, so plant flowers in sunny spots. Morning to afternoon sun is best.
Butterflies lay their eggs on host plants that feed their larvae. Each butterfly species has its own food preferences. The more variety you have, the more butterflies you will attract.
Native Flowers for Butterflies
Are native flowers better for attracting butterflies than non-natives? You may notice that butterflies visit both types of flowers. So what's the big deal?
If you look at the list of butterfly host plants, you'll see that butterflies are picky about where they lay their eggs. Some butterfly larvae can only eat the leaves of a very small range of plants. For example, Monarch larvae can only feed on members of the milkweed family. Many of the host plants happen to be native wildflowers.
One reason why butterflies are endangered is because their host plants in the wild are disappearing. Host plants may not seem as glamorous as flowers, since watching adult butterflies is more entertaining than watching caterpillars. But we need to consider the needs of the butterfly in all its stages of life, including the "ugly duckling" stage.
Here's my list of the best flowers for butterflies and the host plants that support them through all the stages of life.
