Observations by Gary Fewless for Green Bay WI (Lat.N 44.51° Long. W 88.02° ), except as noted. For flowers lacking conspicuous petals or sepals I define "anthesis" as release of pollen by mature anthers.

July 2013 Mouse-over the photo for the identity of the subjectwhite false indigo

July 30
mushrooms There was an abrupt appearance of mushrooms on one of the trails in UW-Green Bay's Cofrin Arboretum. Two days ago, there were no mushrooms there.
July 28
goldenrod Giant goldenrod (Solidago gigantea) has begun to flower. You can find more photos and explanation here. In spite of the common name it isn't necessarily the largest species of goldenrod, but it is one of the earliest to begin flowering in our area.
July 26
prairie dock Prairie Dock (Silphium terebinthinaceum) has begun to flower in planted prairie.
July 25
honeysuckle honeysuckle The weedy, alien honeysuckle shrubs are now conspicuously in ripe fruit. There are 3 species in this group in the Green Bay area and the color of the fruit is not diagnostic for separating the species--orange and red both occurring in the same species though usually not on the same plant.
July 23
orange touch-me-not Orange touch-me-not (Impatiens capensis) is now in flower. The flowers are highly modified and the bright color is quickly noticed.
July 22
field flowers Here's a photo of some colorful flowering plants in a local field. Click on the thumbnail for a larger photo with labels for the plants. The St. John's-wort, hoary alyssum and wild carrot are alien species.
July 21
purple coneflower The purple coneflower (Echinacea purpurea) has begun to flower in planted prairies locally. It is not native this far north, but it does pretty well when planted. [pale purple coneflower (Echinaceae pallida) has been in flower since late June]
July 20 The hot, humid weather has ended. Today's high temperature was 74° F and the humidity is much lower.
July 19

High temperature 93° F.

The large bull thistle (Cirsium vulgare) has begun to flower.

July 18

Hot and humid weather has settled into Wisconsin, with Green Bay high temperatures of 89, 91, 92, 92 (° F) the last 4 days, and dew points in the mid 70's. Today to 89° and dewpoint 74° before 11:00 a.m., with 93° F predicted. [the high did in fact reach 93]

monkey flower Monkey flower (Mimulus ringens) is now in flower.
July 17
culver's root Culver's-root (Veronicastrum virginicum) in flower in planted prairie on UWGB. It probably began a little earlier on sandier soils.
July 14
Canadian tick-trefoil (Desmodium canadense), lead plant (Amorpha canescens), compass plant (Silphium laciniatum) and Mountain mint (Pycnanthemum virginianum) have begun to flower in prairie plantings since July 6.  
July 6
day-lily Day lily (Hemerocallis fulva) is now in flower. This is an alien species from Asia that is very widely planted. Although it doesn't appear to spread often by seed, once planted it expands as large clones which last for decades in many cases, as along roadsides.
July 5 Virginia creeper (Parthenocissus vitacea; also called P. inserta) is now beginnining to flower.
July 3 Water plantain (Alisma triviale) began to flower today on the UW-Green Bay campus.
July 2
There are just a few open flowers of chickory (Cichorium intybus) now, but we should be seeing very large numbers very soon.  
July 1
ox-eye Ox-eye (Heliopsis helianthoides) began to flower today in UW-Green Bays prairie. This is the latest date for start of flowering in 28 years.
