On Asclepias syriaca.
Growing in a remarkable pine-oak savanna remnant.
In sand pine scrub habitat.
Growing at the upper edge of a roadside ditch.
A weed in a lawn.
My thanks to Kevin Doyle (Botanist, Wisconsin Dept. of Natural Resources) for facilitating this visit.
Currently in iNaturalist this species is being treated as Varronia globosa or V. humilis. The Atlas of Florida Plants currently uses V. globosa as the accepted name, so I'm following that.
Roadside grass with enormous panicles.
Growing in a sandy Pinus palustris & Quercus laevis savanna.
Weedy roadside.
Eragrostis ciliaris var. laxa.
Weed in a frequently mowed lawn.

Growing with Vaccinium pallidum and V. stamineum.
Growing in a mesic sandy-loam prairie.
Thanks to Floyd Catchpole and Brad Semel for bringing me to this site.
Feeding on Viola rafinesquei (V. bicolor).
Branches easily accessible near the ground thanks to this forest getting roughed-up by Hurricane Irma several months earlier.
Growing in a mesic, sandy loam prairie.

All cleistogamous flowers at this point. Growing in a sandy prairie opening in a forest dominated by Quercus alba, Q. palustris, and Q. velutina (an unusual combination).
Stoloniferous plants growing in a humid forest that unfortunately was filled with Laportea canadensis.
A weed in a frequently mowed lawn. How it arrived here is a mystery.
Identified by Robert Naczi, botanist at the New York Botanic Garden.
These things infested a previously healthy hybrid chestnut (Castanea dentata × mollissima), killing it nearly to the ground, while leaving an adjacent one alone. The infested branches, when cut, smelled fermented. The excavated tunnels were lined with fungal hyphae.

Growing in an open swamp forest.
Growing at the edge of a Sphagnum bog.
Shrubs up to 1 meter tall.
My thanks to Albert Garofalo for bringing me to this site.
According to Albert, Carex lupuliformis also is present but rare in this wetland forest, but apparently not this part of it, and C. lupulina is much more common throughout this site.
A problematic weed in boggy pots, not (and never) cultivated.
Photographed over a few weeks in April, 2013.

My thanks to Albert Garofalo for showing me this woodland.
Enormous tree for this species, perhaps 60ft tall and 2ft DBH. If it hadn't been flowering, from a distance I might have thought it was an old oak. Last year's infructescence collected off the ground beneath the tree.
Growing in a very dry, frequently mowed roadside lawn.
A weed with potted plants.
Lawn weed.
A substantial weed in pots and a yard.
