There was a time in the past when all the flowers are wildflowers! When people started to have houses and parks, there are also plants that became domesticated and cared for by the people. Domestication probably started for food, for medicinal values, and eventually for aesthetic reasons. Some wildflowers in some locales maybe domesticated in others, as per the cliche "beauty is in the eye of the beholder". Then after decades or centuries of domestication, some plants eventually become wild again. These could be those left by some people, escaped domestication, and reverted back to become wild.
Our wildflowers in our area are not as colorful or attractive to men as those in colder climes. Besides, they are not very plentiful in contiguous locations. I uploaded here in pairs some that are found around our area in the province. They might not be lovely for humans, but they are much favored by butterflies.
Wedella trilobata
This is previously a ground cover for some landscapes. It has been declared invasive in some US cities. Maybe this in our area is planted as ornamental plant but eventually become invasive and conquered an area nearby. I don't mind it near our area as the Tiny Grass Blue butterflies love this.
