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.

The fruits of Sambucus racemosa (red elderberry) have abruptly turned a bright red in Forest County.

Scutellaria galericulata (common skullcap) is in flower, Forest County, WI.

Tradescantia ohioensis (spiderwort) is about at flowering peak now on UWGB prairie.

Phalaris arundinacea (reed canary grass) is in about peak flower along highways in Oconto County.

Bromus inermis (smooth brome), Hieracium aurantiacum (orange hawkweed) and Hieracium piloselloides (yellow hawkweed) are in about peak flower along Highway 8 in Marinette and Forest Counties.

June 23 A very hot day in northeastern Wisconsin, with most areas reaching the 90's F. Rhinelander tied the record high temperature of 95° F set first in 1911. Green Bay also reached 95° F and remained above 90° until after 8:00 pm. Green Bay has had only about 1/3 inch of rain since June 8th.
June 24 Ilex verticillata (common winterberry holly) is conspicuously in flower in Brown County.
June16 Maianthemum racemosum (false solomon's-seal) conspicuously in flower in Forest county.

I returned to Green Bay after an absence of about 2 weeks of travel in South Dakota, Wyoming and Colorado. Green Bay weather has been cool during my absence, but if it is any consolation, it snowed in Rocky Mountain National Park and we were glad to have hooded jackets and gloves even at middday at high altitude. Cold in the Black Hills of South Dakota too. I'll try to add some photos later, but there is much to do to catch up here.

The following species were in flower on the UW-Green Bay campus when I returned: Baptisia alba (white wild indigo), Baptisia bracteata (cream wild indigo), Anemone canadensis (Canada anemone), Rosa blanda (pasture rose), Rosa rugosa (beach rose), Lupinus perennis (wild lupine), Poa pratensis (Kentucky bluegrass), Vitis riparia (river bank grape), Robinia pseudoacacia (black locust), Iris pseudacorus (yellow iris), Heracleum lanatum (cow parsnip), Hydrophyllum virginianum (Virgninia waterleaf) Potentilla simplex (common cinquefoil), Veronica officinalis (common speedwell), Rubus idaeus (red raspberry), Comandra umbellata (bastard-toadflax), Hordeum jubatum (mare's-tail), Euonymous alata (winged burning-bush), Cornus alternifolia (alternate-leaved dogwood, some plants were done flowering), Osmorhiza longistylis (long-styled sweet cicely), Maianthemum racemosum (Solomon's-plume), Viburnum trilobum (high-bush cranberry), Sanicula gregaria (clustered black snakeroot), Rubus flagellaris (northern dewberry), Galium mollugo (white bedstraw), Crepis tectorum (hawk's-beard), Leucanthemum vulgare (ox-eye daisy), Trifolium repens (white clover), Trifolium hybridum (alsike clover), Trifolium pratense (red clover), Vicia cracca (cow vetch), Alopecurus pratensis (meadow foxtail). Some of these species may have been in flower for two weeks or so and others, such as the yellow iris, cow parsnip and northern dewberry appear to be very recently in flower. Tradescantia ohioensis (spiderwort) is in flower on the planted prairie and it appears to be the first day of flower for this species here. A small number of Geranium maculatum (wild geranium) are still in flower. Viburnum lentago (nannyberry) is mostly done flowering.

The "cotton" of Populus deltoides (eastern cottonwood) seeds is conspicuous in City of Green Bay and is at about its peak.

Green Frogs are calling in Prairie Pond on UW-Green Bay's Cofrin arboretum.

Pearl crescent butterfly conspicuous in sunny sites.

Acer saccharinum (silver maple) fruits are dropping.

Spittlebugs are conspicuous on a variety of plants.
