Eupatorium rugosum-Ageratina altissima

Eupatorium rugosumEupatorium rugosum

Eupatorium rugosum was the original name for the ‘white snakeroot’ but due to the toxin it contains, it has been replaced in the Asteraceae family and is now named Ageratina altissima. This plant is native to eastern North America. This plant was observed 2014 September 12 in Newark, Ohio in an open area along the edge of a mixed mesophytic forest with an overstory dominated by Quercus rubra (red oak),  Quercus alba (white oak), Acer saccharum (sugar maple), and Juglans nigra (black walnut) and an understory is dominated by Podophyllum peltatum (mayapple), grass and other herbatious plants. This plant was found growing in a moist soil on the south-eastern side of an Acer saccharum (sugar maple) tree. This plant can be best described as a small white flowers in clusters near the top with hair-like tips; opposite leaves (a pair of leaves are attached to a node), ovate (spare-like), and a serrated margin (toothed edge).

Prunella vulgaris

Selfhealimage

Prunella vulgaris also known as Selfheal or Heal-all of the mint family, Labiatae, was observed 2014 September 12 in Newark, Ohio. Prunella vulgaris are native to North America. This herb was found outside in an open-cultivated lawn, growing along the west side of a shady, limestone driveway, on a slightly-downward slope in moist soil. This herb can be best described as a purple-white flower in a green, spiked, square-cluster. The flower itself has a purple-upper lip that covers a three-lobed, white-lower lip. The leaves are arranged in opposite pattern and the leaves have an entire margin (smooth edge), lance-shaped (long spare-like), and appear dark green. An interesting fact about this herb is that it is edible, the leaves may be eaten in salads; the whole plant may be boiled and eaten; the above ground parts of the herb may be powdered and brewed as a tea. It is also a medicinal herb that will heal sore throats, thrush, gum infections, irritated skin fever, diarrhea, and internal bleeding.

Impatiens capensis, otherwise known as the ‘spotted jewelweed’ or ‘spotted touch-me-not’ of the family, Balsaminaceae, was observed 2014 September 12 in Newark, Ohio.  Impatiens capensis are native to North America. This plant was found outside in an open, shaded-cultivated lawn, growing along the north-east side of a building in moist soil. This plant can be best described as an orange flower with red-brown spots; the flower is made up of a three-lobed corolla (petal), a calyx (sepal) about an inch long with a short inward-curved spur at the back; alternate leaves (a single leaf attached to a node) that are egg-shaped with crenate margins (round-toothed edge); and the stems are succulent (thick and fleshy) with darkened nodes. Interesting facts about this plant are the fruits and the leaves. When the fruit becomes ripe, the slightest touch can make the seeds explode out of the pod, which is why it is named ‘touch-me-not’ (below is a photograph of a ripened fruit with seeds in the pod. Lastly, when the leaves are submerged underwater they appear silver or ‘jeweled’ given the name ‘jewelweed’ (attached is a video of a Impatiens capensis leaf submerged underwater ).
