Invasive species. See: http://invasoras.pt/en/gallery/erigeron-karvinskianus-en/
Been watching an opposum corpse deteriorate for most of this year. Was very recognizable at first but a little grim looking now. Withholding picture for now.
This has the same low, arching growth form as heath aster, but the petals appear joined and the center of the flower is purple and doesn't appear to be multiple flowers.
Grows along a trail by the river in profusion. Mostly open canopy, nearly full sun.
Also part of the edible plants tour. Incredibly spicy leaves. Growing in a seep stream before it connects with the Elm Fork of the Trinity River. According to Texas A&M Horticulture, introduced from Europe. I doubt it's invasive, though.
Shriveled too quickly to be pressed. Sample was photo + taste only.
Also along a roadside. 3-lobed fuzzy seeds remind me of snow on the prairie, but the leaves certainly don't match. Haven't found this one in my guides yet.
A fisherman was kind enough to let me get a couple of pics of this fella. This was NOT a catch and release.
Seeking to document observations of non-native introduced species outside of their original homelands. Observations must be of organisms that were introduced to an area by humans recently (established populations of introduced species are okay), not natural shifts in range, or migrations.
