Ageratum, frequently called Blue Mistflower or Purple Mistflower, is a weed in my yard, a wildflower, and a butterfly nectar source. I've seen Monarch Butterflies, Soldier Butterflies, and a Monk Skipper Butterfly sip nectar from it.

This Purple Mistflower was in a pot on my porch, but our lengthy drought was too much for it. Since it died of thirst, I've found several more flowers in my lawn that I've been mowing around, and the butterflies enjoy them as much as I enjoy watching the butterflies. I need to transplant them to a garden area, but I'm waiting for the water restrictions to go away before I do much more with my plants.

This Soldier Butterfly has its proboscis all the way down in the flower, as does the Queen Butterfly below.

I recently found a nice weedy spot with all sorts of flowers in bloom, but both the Soldier and the Queen kept flitting from one Mistflower to another, completely ignoring the other flowers.
