Dandelion (INN) not ranked in TN Taraxacum officinale* / Composite Family
The name dandelion comes from the Americanization of the French "dent de lion," meaning "tooth of the lion." The common name in German (Löwenzahn - pronounced "luhr-ven-tsan"), Norwegian (Løwetann) and Spanish (diente del león) also means "lion's tooth," from the sharp, jagged lobes of the leaves. Dandelions are self-pollinating, which makes them an even more pesky weed. Since it is such a common weed, this is a good flower to use to study the anatomy of a composite flower. Each "flower" is actually many individual florets. Tear a flowerhead in half and remove a single little flower. Each one has a curled, Y-shaped pistil, a stamen with pollen, an ovary (which will become a seed), and the pappas, the "parachute," which is so enticing for children to blow and make a wish. This picture was taken in Oak Ridge in early March. The little insect is a hoverfly, not a bee; some people call them "news bees".

Coltsfoot close-up Tussilago farfara* Huntsville, TN (Scott Co.) March 21, 2009 This was one of those "U-turn plants", I made my husband turn around and drive back so I could get a photo! This makes plant #710 on this site of wildflowers from East Tennessee! Coltsfoot is a non-native that blooms very early in the spring and the flowers come up before the leaves appear. If you see the leaves, it is too late to enjoy the flowers! These plants were growing in a thick bank of broken shale. I was glad these were growing low enough to photograph them, I would not have been able to walk up the steep, loose gravel bank. 1809

It can be very difficult to differentiate between the two without looking closely.

Kidney-leaf Buttercup Ranunculus abortivus / Buttercup Family
Not all buttercups are bright and showy. I found this one blooming in Oak Ridge in April. Ranunculus means "little frog" because it often grows in wet areas. The guys who named these plants must have had quite an imagination! I don't know about the meaning of the species name of this plant, abortivus. I wonder if the plant affects the unborn young of animals? All buttercups are poisonous, they contain an irritating oil in the stems and leaves called protoanemonin. The poison causes abdominal pain in the animal, severe diarrhea, convulsions, and finally death. If cows eat the plant their milk will be bitter and reddish in color. Since buttercups have an unpleasant taste, livestock usually avoid eating them unless other food is not readily available. Sometimes buttercups will overtake a field.

I was really surprised to see this plant blooming in the Obed River in Morgan County, TN! I have usually seen it in quiet lakes and streams in southern Alabama and the Panhandle of Florida. It is related to Green Dragon, Arrow Arum and Jack-in-the-Pulpit. The developing leaves will emerge from the water in a few days. It is interesting to see the flower buds still under water. Notice how the plant is growing between the cracks in the rocks on the river bottom. This was plant #699 for my East Tennessee wildflower list on this website. Perennial
