Cornus mas

At first I thought this was another spicebush, but it just didn't look right when I got close to it. It's Cornus mas, which is in the dogwood family. This is on Purdue campus on the NE corner of State St. and Intramural. By July the fruit will ripen and it is good to eat.

These pictures were taken March 29, 2009.

There is another Cornus mas by the Undergraduate Library.

This is henbit (Lamium amplexicaule). In the early spring henbit and its close relative purple deadnettle can turn cornfields into seas of purple. This picture was taken March 27, 2009 along Williams Street in West Lafayette.

Hamamelis vernalis on Purdue campus

This is a row of Hamamelis vernalis along the north side of Stewart Center, showing the yellow flowers. This species flowers in the early spring. Picture taken March 25, 2009. You can find another couple of Hamamelis vernalis bushes on the west side of Stanley Coulter Hall.

This is not our native witch hazel that you find growing wild in Indiana woods. That is Hamamelis virginiana, and that flowers in the late fall.

This is harbinger-of-spring (Erigenia bulbosa). It is one of the first spring wildflowers to appear in the woods. This picture was taken at the Eunice Bryan Nature Preserve in Clinton County March 24, 2009. Only the Erigenia was flowering, no other spring wildflower was out yet. The spring beauty (Claytonia) leaves had started to appear but no flowers yet.

This little insignificant plant is Veronica hederifolia. At this time of year it is growing in every yard in Lafayette. If you are reading this and this post is still fresh go out in your yard and get on your hands and knees and you ought to find it. With a magnifying glass the tiny flowers show their beauty. This picture was taken March 22, 2009.

Revision Mar. 4, 2012:  This plant is Veronica polita, not V. hederifolia.

Happy Hollow Park

At Happy Hollow Park, these are invasive plants. They have been working on getting these out of the park, it seems to be fairly successful. There is a lot less of this than there could be. Notice the bush honeysuckle (Lonicera maackii) is already starting to leaf out. In spring it gets a headstart in competition with the native plants. There doesn't seem to be much of the honeysuckle, this is just a small sprout I found. This picture was taken at Happy Hollow Park on March 18. The other plant is garlic mustard (Alliaria petoliata). Not too bad an infestation of this but there is rather a lot of it at the high part of the main trail on the north end of the park.

The yellow flowers of forsythia mark some of the first days of spring. You can find these forsythia shrubs planted at the east end of the pedestrian bridge over the Wabash. The picture below is a view of the still flooded Wabash River looking upstream. Both pictures were taken March 17, 2009.

You can follow the gage that measures the river height and flow here:
