Among the worst invasive species that are present at Hidden Springs wetlands are purple loosestrife ( Lythrum salicaria ), mis-named Canada thistle ( Cirsium arvense ), and reed canarygrass ( Phalaris arundinacea ). (boisefrontnature.com)
Large patches of purple-flowered Canada thistle ( Cirsium arvense ) grow at the edge of the marsh, interspersed with tall stalks of poison-hemlock ( Conium maculatum ) covered with small white flowers. (boisefrontnature.com)
Vulgare1
I found some Bull Thistle (Cirsium vulgare) a couple days prior, and knew the general area of which to find them, but I was unable to locate the plants in all the greenery when I went out. (blogspot.com)

Innumerable hybrids and cultivars of flowering crops have sprung from a whole bunch of 1000's of species. (my-plant.org)
In addition, there are numerous cultivars and hybrids you may come across that probably originated at a local garden center. (birdwatchinghq.com)

Avoid those garden centres selling Sedum 'Autumn Joy' or 'Herbsfreude' which is a nectar-free hybrid - you definitely need the spectabile species, and preferably several of them. (sussex-butterflies.org.uk)
Meadow1
Prairie fens typically occur as part of large wetland complexes that support a variety of wetland communities including emergent marsh, southern wet meadow, wet prairie, wet-mesic prairie, southern shrub-carr, and rich tamarack swamp. (msu.edu)
Swales where standing water is present through most of the year typically lack an overstory and instead are dominated by sedges ( Carex aquatilis and C . stricta ), twig-rush, marsh marigold ( Caltha palustris ), swamp candles ( Lysimachia terrestris ), sweet gale ( Myrica gale ), and swamp cinquefoil ( Comarum palustre ).
