I will not attempt to identify all these butterflies (being lazy), so if you know what they are, feel free to comment about it. I will restrict my identification to, "I think this is a (blank)", or "white butterfly" kind of thing.
Most of these pictures were taken in the Herbal Tea Garden. This garden is a few years old and is maturing up nicely. I posted about planting it in the no-till fashion here.
It's hard to get across in these pictures the sheer numbers of butterflies that were flying everywhere, but each plant had at least ten butterflies on it at a time!
This plant with blue flowers in the Herbal Tea Garden is Nepta, or Cat Mint. You can see several sulfur butterflies on it or flying near.
Sulfurs on the cat mint. I looked this up - its an Orange sulfur.
