Though I’ve seen these flowers before growing with weeds my whole life, I had never really stopped to think about what they were. Turns out, they are the Senecio Ampullaceus, or Texas Groundsel. This plant flowers, in Texas, in the spring season and grow to be surprisingly tall. Although this flower was a lone ranger, typically they grow in groups amongst large patches of weeds. Weeds can pesky and ugly to look at, but this bright little flowers are a sight for sore eyes!
