Tassel flowers in my lawn come in two colors: red (Emilia fosbergii) and
lavender (Emilia sonchifolia).
I've seen
Cassius Blue,
and
Tropical
Checkered Skipper Butterflies sip nectar from the purple flowers;
it's a good
butterfly nectar plant.
Some people call these little flowers 'Paintbrush' because they often
dangle flower down, showing just a small wispy bit of color like an
artists brush with a dab of paint on the tip.
Tassel flowers get puffball seed heads like the Dandelions so many
children blow and make a wish as they disperse in the breeze.
Each floret in the composite makes one seed which is topped by a
translucent white whirl of silken threads, a biological paraglider to
let it waft on the breeze to a new home.
