Bald cypress leafing out

The bald cypress (Taxodium distichum) is a coniferous tree but it loses its leaves in the winter. This bald cypress is just now getting this year's leaves. The natural habitat of bald cypress is low wet soil, but this tree is on rather high ground so it likely was planted there many years ago. In Knox County, April 8, 2010.

Dame's rocket

Dame's rocket (Hesperis matronalis), at the boat ramp at Hazelton in Gibson County. The White River is in the background and is getting high. The picture was taken April 8, 2010, this might be underwater tomorrow according the the flood prediction:

Often when people find a patch of dame's rocket growing in their yards they will leave it unmowed as the flowers are so striking.

Turtles at a sinkhole

These turtles were basking in the sun at this sinkhole in Orange County. This was the best picture I could get, they all spooked and jumped in the water when I got closer. I can't see from the picture exactly what species turtle they are, could be map turtles (Graptemys geographica) or painted turtles (Chrysemys picta). Picture taken March 31, 2010.
