At Deep Woods we came across two types of plants that have fruits that tend to stick to people or animals.
The first was a type of bur producing plant called White Avens (Geum canadense). This is a plant with alternate, simple leaves, and it belongs to the Rosaceae family. The achenes produced have a type of hook that is used for seed dispersal, but many mammal herbivores do not find this plant appetizing. https://www.illinoiswildflowers.info/savanna/plants/white_avens.htm
The second type was a plant called Tall Agrimony (Agrimonia gryposepala). It belongs to the Rosaceae family and has pinnate leaves. The fruits of this plant have rows of bristles that end in a hook and encase a pair of seeds. Tall Agrimony can be found in a variety of conditions but it had a preference for dry, shady areas.
Other species of plants found a Deep Woods are great indicators of the type of environment that they are growing in. These plants have a preference for hilly, acidic environments. These species are often found in sandstone environments with drained soil and rocky outcrops.
One of these plants is Nodding Lady’s Tresses (Spiranthes cernua). These orchids have an alternate leaf arrangement, a spike inflorescence, and like the sandstone makeup of this environment. https://goorchids.northamericanorchidcenter.org/species/spiranthes/cernua/
Next is a tree known as Sourwood (Oxydendrum arboreum). These small trees have an alternate leaf arrangement with leaves that are entire. They love the acidic soil found in locations similar to Deep Woods as well as the well drained soil in the area. https://www.uky.edu/hort/Sourwood
Another plant that is perfectly suited for the Deep Woods Environment is Lady’s Slipper (Cypripedium reginae). These orchids can be distinguished by the large pink and white flower protruding from broad, alternate leaves. These plants are also a big fan of the acidic soil conditions and thrive in the hilly environment. https://www.fs.fed.us/wildflowers/plant-of-the-week/cypripedium_acaule.shtml
One more plant that likes the conditions provided at Deep Woods is Shining Clubmoss (Huperzia lucidula). Shining Clubmoss also thrives in the acidic environment and makes itself at home throughout the numerous hills and rocky outcroppings.
