Sochan (Rudbeckia laciniata). It's up and ready to eat. This is the good stuff! This is a picture of sochan near the Wabash River in Tippecanoe County. Look for it where the river floods at times of high water. Eat it now while it's fresh out of the ground. By summer it will taste like a mouthful of turpentine. Picture taken April 10, 2011.

WARNING: Don't eat the poison hemlock! That's up and green too. Make sure you can tell the difference.

Spring Beauty and Toothwort getting ready to flower

In the Scifres-Maier Woods in Celery Bog Park, a toothwort (Cardamine concatenata) and a Spring Beauty (Claytonia virginica) are just about ready to flower. These are two of our commonest spring wildflowers. Rust fungus is growing on the Spring Beauty, adding some color to the natural world close to the ground. The rust that lives on Spring Beauty is called Puccinia mariae-wilsoniae. Picture taken April 5, 2011.

Phellinus robiniae on Robinia pseudoacacia

This shelf fungus is Phellinus robiniae. The tree is a black locust tree (Robinia pseudoacacia). The vine climbing up the black locust tree is Japanese honeysuckle (Lonicera japonica).

REVISION 1/12/2013:  The vine is not Japanese honeysuckle, rather it is wintercreeper (Euonymus fortunei)

 The pale blue green spots on the top of the shelf are lichens. This tree is in a fencerow in Shelby County near Shelbyville.

A view of the underside of the same Phellinus. Pictures taken April 1, 2011.

Japanese honeysuckle (Lonicera japonica) is an invasive plant that is common, especially in southern parts of Indiana. These fencerow trees are covered with Japanese honeysuckle vines.

REVISION 1/17/2013:  These vines are not Japanese honeysuckle, but rather they are wintercreeper vines (Euonymus fortunei) which is another invasive vine that is a big problem in Indiana.

Both wintercreeper and Japanese honeysuckle vines keep their leaves throughout the Indiana winter, staying more or less green. These pictures were taken in Shelby County near Shelbyville, April 1, 2011.

A closer look at the wintercreeper vine seen in the previous picture.
