Purslane (Portulaca oleracea) is another plant of disturbed areas, it seems to be everywhere. It's only around in the summer, you don't see it later in the year. One of the best wild plants to eat, gardeners spend a lot of effort trying to get rid of purslane when it's a better plant than what they are trying to grow. This purslane is on the sidewalk on State St. in front of the University Book Store, near Grant St, about 6 pm, July 30,2009.
This is the same purslane plant, about 10 pm July 29, 2009. It's getting dark out and the leaves are rolling up for the night.
This carpetweed (Mollugo verticillata) is at Purdue Hort Park, July 29, 2009. Carpetweed never gets too far off of the ground. From where it sprouts out of the ground it grows horizontally in any direction there is room for it. Carpetweed is another pioneer species that grows where we have taken away the original vegetation and because of this it is very common.
This milk purslane is at Purdue Hort Park, July 29, 2009. The scientific name is Chamaesyce maculata. Once it was classified as one of the Euphorbias but now it is considered a Chamaesyce. This is a very common plant. Look down at your feet as you are walking around and you'll see some. Break off a bit of stem or leaf and the milky latex sap oozing out will identify it.
Monotropa uniflora, or Indian pipe. The lack of chlorophyll gives Indian pipe its ghostly white appearance. It depends on fungi in the soil around it for nutrition. This is in Purdue's Hort Park Woods (Stewart's Woods), July 29, 2009.
This Vernonia gigantea is just now beginning to flower, you can see most of the flowering buds here are still unopened. Picture taken July 24, 2009.
The common name for Vernonia is ironweed. In the Hoosier way of saying things, that comes out more like "arnweed".
Ironweed adds a familiar bit of purple color to old fields all over Indiana between now and autumn.
This is just north of the Purdue football stadium. The land is marked as a wildflower garden, it seems most of what is here is big bluestem grass (Andropogon gerardii) and rosinweed (Silphium integrifolium).
This sensitive pea (Chamaecrista fasciculata) is along the trail on the west side of Celery Bog Park. This is a native plant, but this here was likely introduced to give the park a pretty wildflower appearance. Unfortunately just south of this they mowed everything down. Didn't have that pretty planted flower look.
This bur cucumber plant (Sicyos angulatus) has spread over the waterside plants and is reaching in vine for further support. Along the trail at north end of Celery Bog (not really a bog), July 24, 2009.
Vega will transit zenith at any point at latitude 37.7837 degrees north once every sidereal day. From the place of the silk tree this will be a little bit down the road past the middle of Crothersville. Link to sidereal day:
Tonight, July 22, 2009, Vega transits zenith at Crothersville at 8:21 pm local time.
Wood nettle (Laportea canadensis). A common sight in the deep Indiana woods. This nettle will sting like Urtica dioica, if you brush by it it's best you're wearing long pants. This wood nettle is at Pioneer Mothers' Memorial Forest in Orange County, July 18, 2009. Link to Pioneer Mothers' Memorial Forest:
This picture was taken yesterday, July 18, 2009. The yellow flowers of goldenrod (Solidago) is a common sight in late summer and this is the first day I've noticed goldenrod flowering this year. This is along State Highway 160 in Scott County near the Washington County line.
This is one kind of the mountain mints, Pycnanthemum virginianum, in wet ground in a vacant area near Wabash Avenue. The tall grass behind the mountain mint is Phragmites australis, a common sight in ditches. The dark blue-green bugs on the flowers could be sphecid wasps, possibly Sphexor Chlorion.
Wild bergamot (Monarda fistulosa), along the trail between South 9th St. and Beck Lane. Monarda is a common sight along roadsides and vacant land in the summer. The Monarda along the trail could be of an introduced genotype like the other prairie introductions here. Or it could have been growing here in the Lafayette area all along. The grass amongst the bergamot in the right side of the picture is little bluestem grass (Schizachyrium scoparium), another prairie introduction. Picture taken July 16, 2009.
This fruiting head of smooth sumac (Rhus glabra) is along the trail between South 9th St. and Beck Lane, July 16, 2009. Sumac turns a glowing brilliant red in the fall. Patches of sumac are the first to turn color and stand out amongst the green trees as a beautiful red.
This cottonwood leaf (Populus deltoides) is along the trail between South 9th St. and Beck Lane in Lafayette. The little rust colored spots on the leaves is a Melampsora rust fungus. This fungus is a very common inhabitant of cottonwood leaves, it adds a bit of color for those who take the time to look closely. Picture taken July 16, 2009.
This purple coneflower (Echinacea purpurea) is part of the prairie planting along the trail between South 9th St. and Beck Lane on the south side of Lafayette. Echinacea purpurea is a native plant. It is very popular as a garden plant and you are more likely to encounter it where it has been placed rather than in its natural habitat. Picture taken July 16, 2009.
This is leadplant (Amorpha canescens). This is growing along the trail between South 9th St. and Beck Lane. Picture taken July 12, 2009. This is another of the prairie plants that were introduced to this area.
This big Silphium laciniatum is on the trail between South 9th St. and Beck Lane. No doubt this Silphium was introduced here along with the other typical prairie plants when they created the public trail. Pictures taken July 16, 2009.
As you can see much of the land along the trail is wasted by senseless mowing. Some people just gotta mow stuff down somewhere. The paved trail is plenty wide for access and having it unmowed to the edge of the pavement would be an improvement and save money too.
This is cup plant, Silphium perfoliatum. The leaves surrounding the stem merge to form a cup that holds rainwater. This is alongside the trail that passes by Williamsport Pond in West Lafayette. Picture taken July 15, 2009.
This cup plant is in a vacant lot near Teal Road in Lafayette. Due to the local mania for mowing it might not survive long enough to show its flowers. If it doesn't get mowed down it will be one of the first true prairie plants to recolonize the land. This picture was taken July 12, 2009.
The small pink flowers on the left are crown vetch (Securigera varia) and the white flowers at the top are Queen Anne's Lace (Daucus carota).
This is a black walnut tree (Juglans nigra) overhanging Williams St. in West Lafayette, near South River Road. The nut will form inside the green fruits. Picture taken July 12, 2009. Link to black walnut tree (Juglans nigra):
