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.

June 2008 Mouse-over the photo for the identities of the three subjects wild rose, green frog, northern bush honeysuckle

June 30 Heliopsis helianthoides (false sunflower or ox-eye) is in flower in UW-Green Bay's prairie.
June 29 Daucus carota (wild carrot or Queen Anne's-lace) is in flower, Allouez.
June 28 The following plants are now in flower on the UW-Green Bay campus: Cichorium intybus (Chickory), Nepeta cataria (catnip), Asclepias syriaca (common milkweed)
June 26 I'm starting to see open flowers of Melilotus alba (white sweet clover) in the Green Bay area.
June 25 Tradescantia ohioensis (spiderwort) is at about the peak of flowering in the UW-Green Bay prairie.
June 21 Cornus racemosa (gray dogwood) is now in flower in the Green Bay area.
June 20 Rhus hirta (staghorn sumac), Cirsium arvense (Canada thistle) and Agropyron repens (quack grass) are in flower now in the Green Bay area.
June 18 First fully open flowers of Hypericum perforatum (St. John's-wort).

Flooding is so widespread and severe in southern Wisconsin as to exceed my ability to describe it here. Federal disaster designation has already been assigned to Columbia, Crawford, Milwaukee, Racine, Richland, Sauk and Vernon counties and FEMA representatives are assessing Fond Du Lac, Waukesha, Kenosha, Marquette and Iowa counties today to determine their eligibility for disaster relief. Eastern Iowa seems to be in even worse condition with large areas of the state flooded, numerous road closures and evacuations.

Though it seems trivial compared to the flooding news, I will note here that Trifolium repens (our common white clover) is having a banner year in the City of Green Bay. In part this may be due to the wet conditions that prevent people from mowing lawns as frequently as they might otherwise do.

June 15 Flooding continues over a large portion of southern Wisconsin and also widely in Iowa and northern Illinois.
June 12

Rosa blanda (pasture rose) is now in flower.

More heavy rain in southern Wisconsin and widespread flooding.

June 11

Leucanthemum vulgare (Ox-eye daisy) and Melilotus officinalis (yellow sweet clover) are in flower; both are naturalized aliens.

Galium boreale (northern bedstraw) is in flower.

June 10 The increasingly common alien grass Dactylis glomerata (orchard grass) is in flower (anthesis).
June 09

Heavy rains over the weekend caused flooding in southern Wisconsin. Among the most notable floods was in the Wisconsin Dells area which received over 12 inches of rain, resulting in the failure of an earthen dam early Monday, draining Delton Lake and ultimately washing out about 300 feet of County Highway A.

Populus deltoides (eastern cottonwood) is now releasing mature seeds. The long white hairs attached to the seeds help to disperse the seeds and are the inspiration for the name "cottonwood".

This is the first day we noticed the white cheek patches on Canada Goose goslings in the pond near our home. We might have noticed earlier if they were not so far distant, so this is not an absolute developmental observation.

Robinia pseudoacacia (black locust) has begun to flower, UW-Green Bay.

June 06 Strong winds as a front moved through Wisconsin today blew down many trees and caused widespread electrical power outages in northeastern Wisconsin.
June 01 The early individuals of Poa pratensis (Kentucky bluegrass) have begun to flower (anthesis). This pollen is a significant source of "hayfever" sympoms at this season. Many "summer colds" are actually allergic reactions to pollen and mold spores. Other species now in flower include: Tragopogon dubia (yellow goat's-beard) and Lotus corniculatus (bird's-foot trefoil).
