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 2007

June 30 Monarda fistulosa (purple bergamot) in flower widely. There may have been a few plants in flower a day or two earlier.
June 29

Home thermometer in northwestern Marinette County registered a low of 39° F this morning and radio forecasts warned of frost in low areas. Green Bay's low was 45° F--cold enough for late June.

The first flowering plants of Epilobium angustifolium (fireweed) were noted today, Marinette County (Gary Fewless.

June 28 Silene vulgaris (bladder-campion) in flower, Marinette County. I probably missed the start of flowering.
June 27 Hemerocallis fulva (orange daylily) in flower, City of Green Bay and widely in adjacent areas. Also Trifolium aureum (yellow hop clover) in flower, Marinette County.
June 25 Agrostis gigantea (redtop) in flower widely in northeastern Wisconsin.
June 22

Mentha arvensis (wild mint) has begun to flower, UWGB. Also Euphorbia corollata (flowering spurge) and Echinacea pallida (pale purple coneflower) are in flower in the planted prairie at UWGB. Fruits of Morus alba (white mulberry) are beginning to ripen, UWGB.

I've added a few more photos of the tornado in Oconto County on June 7 including a broad panorama that might give a better sense of the scale involved.

June 21 A few exceptionally early plants of Cichorium intybus (chickory) and Melilotus alba (white sweet clover) were in flower today along Bay Settlement Road adjacent to UWGB. I've noticed a couple of other very early plants in that area also. It may be the result of seeds brought in on construction equipment when this portion of Bay Settlement Road was expanded a couple of years ago. We'll see if they persist in future years.
June 20 Thunderstorms and hail in some locations in NE Wisconsin, but Green Bay received only 0.13 inches of rain.
June 19

First few plants of Rudbeckia hirta (black-eyed Susan) in flower, UWGB.

First open flowers noted for Trifolium fragiferum (strawberry clover), UWGB.

June 18

Asclepias tuberosa (butterfly weed) in flower, UWGB.

Green Bay received 0.98 inches of rain today.

June 15

Asclepias incarnata (swamp milkweed) in flower, UWGB.

My digital thermometer registered 97 degrees F. as a high today. The unit hangs on the north side of a picket fence about 3 ft off the ground. So hot it sunburned hosta leaves. City of Green Bay, near UWGB (David Parsons). [the National Weather Service station on the opposite (west) side of town registered a high of 89° F today, gf]

June 14 Typha angustifolia (narrow-leaved cattail), Calystegia sepium (hedge bindweed) and Asclepias syriaca (milkweed) have begun to flower, UWGB.
June 13 Nepeta cataria (catnip) and Geum aleppicum (yellow avens) in flower, UW-Green Bay. Tradescantia ohioensis (spiderwort) is at peak flower in the prairie.
June 12 Sambucus canadensis (black elderberry) in flower, Brown County. Valeriana officinalis (garden valerian) is also in flower. This alien species appears to b spreading widely in northeastern Wisconsin and may yet be an important invasive species on sunny sites.
June 11 Geum canadense (white avens) in flower, UW-Green Bay's Cofrin Arboretum.
June 10 Galium boreale (northern bedstraw) in flower, UWGB.
June 07

Severe thunderstorms swept across Wisconsin today and tornados did considerable damage in northeastern Wisconsin. At least 5 tornados were reported. Here are photos of forest damage, home damage and damage to the town hall for town of Riverview, where a tornado crossed Highway 32 north of Mountain, WI. Here are a few more photos taken June 15 including a broad panorama that might give a better sense of the scale involved.

Galium triflorum (fragrant bedstraw) in flower, Forest County

June 03 Green Bay received a total of 1.74 inches of much-needed rain from June 2 and 3.
June 01 Iris virginica (blue Iris or blue flag) and Rubus allegheniensis (blackberry) beginning to flower in Brown and Oconto Counties.
