8 April 2017 – Spring Wildflower Walk

Little Patuxent River from the River Trail

Today, the Little Patuxent River Trail located on the North Tract of the Patuxent Research Refuge was the scene for a spring wildflower walk sponsored by the Refuge.

Virginia Bluebells among Lesser Celandine

We identified a total of 32 species of plants and one species of lichen. (See list below). The bluebells put on an especially nice display. We did notice that the invasive Lesser Celandine took over more of the area compared to last year.

Looking at a Spicebush.

After the walk along the River Trail, we drove down to the Chickasaw Plum grove. In addition to the Chickasaw Plum we saw some Devil’s Tongue Cactus (Opuntia humifusa.)

A good time was had by all.
