Summary
DescriptionTiny Pink Aster (7138163227).jpg
Symphyotrichum tenuifolium: I found this little pink wild aster blooming in the middle of a dirt road. The flower is about 15mm in diameter. It was the only specimen I saw of it's kind and was growing among the abundant Erigeron quercifolius. Perhaps it is Aster bracei but I don't have adequate references to make that call so for now it will be "tiny pink aster". Sweetbay Natural Area, Palm Beach County.
