Kudzu Pueraria lobata* /Pea Family (INN) Rank 1
The pretty purple and yellow flowers of kudzu smell like grape soda! This vine has been called "a vegetative form of cancer" due to its incredibly fast growth. The plants were once planted for erosion control, however they quickly overgrew other plants and became a terrible weed. Unfortunately, I didn't have to go far to find these flowers, they were growing in my back yard! :( Perennial Where seen: EVERYWHERE!!!, Great Smoky Mountains NP, Warriors' Path SP

Asiatic Dayflower Commelina communis* /Spiderwort Family
Individual Dayflowers last as long as their name implies, one day. Linneas named this plant for the Commelin brothers, although he was a great scientist, he had quite a sense of humor. There were three brothers who were botanists, only two of them made a name for themselves. The flowers have three petals, but only two of them are showy and noticible, kind of like the Commelin brothers! I took this picture in front of the dorm at Tremont in the Smokies. The showy yellow "fake anthers" are attention getters to attract bees, the true pollen-producing anthers are the two long ones below the flower. Annual Where seen: Oak Ridge, Great Smoky Mountains NP

Limestone Wild Petunia Ruellia strepens /Acanthus Family
One difference between this plant and the previous one is the location of the nectar guides. This one has the guides on the side, as if the flower grows sideways! This plant just about drove me nuts trying to figure out its' species. My 3-inch thick "big scientific words" botanical manual describes this plant as having flowers "in subsessile or pedunculate, axillary glomerules from upper nodes" and having "glandular-pubescent, lanceolate calyx lobes." No wonder it drove me nuts!!! I took botany as an elective at UT Knoxville 30 years ago when algae and some protozoa were still considered as being in the Plant Kingdom! Things have changed a lot since then! I didn't have to learn all those difficult botanical terms in Botany 101! I found this plant blooming at the Haw Ridge Greenway in Oak Ridge in late May.

Catmint; Nepeta Nepeta x faassenii* /Mint Family Height: 6" to 24" June 4, 2005
This really was a roadside plant, I found it growing by a bridge on a walking trail along Melton Hill Drive in Oak Ridge. The individual flowers of this plant are pretty with the purple spots. Catnip flowers can be white or pale violet, they have purple dots on the lip. The leaves have small hairs which give them a grayish look, this is a good field identification trait. I smelled a leaf, it is aromatic, but not especially pleasant for a mint. Being a serious cat-allergy sufferer, I avoid them as much as possible, so I've never seen a cat under the influence of Catnip. However, I've heard that they love it and it makes them act crazy. One website I checked stated that Catnip contains nepetalactone, which could be considered "a legal recreational drug for cats"! This plant is not as inticing to cats as true Catnip.

It could be easy to confuse this plant with a thistle, it has hundreds of tiny pinkish-purple flowers and the leaves and stems are very prickly. It is a member of the Teasel family, Thistles are in the Composite family. Teasel is a European import, it can grow in very thick patches along the interstates and other highways. The prickly dried seed heads were once used to "tease" wool. These were found when I stopped at a convenience store with my sisters-in-law in Kingsport; I never pass up a chance to take a picture.

Passionflower; Maypop; Apricot Vine side view Passiflora incarnata /Passionflower Family
This unusual flower is the State Wildflower of Tennessee. The Native American name for this flower is "Ocoee." The common name comes from the crucifixion story. The three pistils represent the nails driven into Christ's hands and feet, the five anthers = the wounds, the long thin corona = the crown of thorns placed on His head, the ten sepals and petals = the 10 faithful Disciples, the tri-pointed leaves represent the spear, and the tendrils = the whips. The small green sphere below the pistils will become the fruit. This picture was taken in Oak Ridge in August. Above view of flower follows.

While I was looking at the newly-opened Passionflowers in my parents' yard in Florida one morning I saw something amazing. The stamens are inverted (the 3 bright yellow ones) when the bud blooms, as the petals, stamens (pointed) and fringed corona opens, the hinged stamens flip over (note the hinges on the 2 flipped anthers on the left). This happens very quickly. I got a movie of them flipping, I hope to get it put on this website soon! 1905
46 Note the extra-floral nectaries (little green nodules) on the sepals of the Passionflower bud. They produce nectar to attract ants to protect the plant from Gluf Fritillary caterpillars and other leaf-eating insects. (See next photo for more information)

The Passionflower is the host plant for the Gulf Fritillary Butterfly. The plant has evolved extra-floral nectaries on the flower sepals and leaf bases to attract ants (see previous photo). Not to be outsmarted by a plant, this butterfly is laying one of her eggs on the end of the vine's tendrils. By the time the caterpillar eats its' way to the end of the tendril, it should be large enough to not be eaten by the ants. Isn't nature amazing?! 1353
