I searched for the name of this tiny purple-blue flower that pops up here and there in my yard, and Florida Ironweed looks like my plant. The flower consists of a bunch of tiny individual flowers, each with five petals.

A Cassius Blue Butterfly paused briefly on my Ironweed, so I put it on my Nectar Plants page, although I haven't noticed any butterflies pause on it since.

Most of the little weed-like flowers I look up are not Florida Native Plants, so I was delighted to find out that this one is.

The seed heads form tiny Dandelion-like puffballs that blow in the wind.

Ironweed flowers are extremely small; they really pushed the limits of my photography skills. This picture shows how little depth of field you get when magnifying a shot, even with a really high f-stop.

It looks like each tiny flower in the cluster makes one seed. Each seed has a circle of silk hairs to help it catch the breeze and journey to a new home.
