White Snakeroot

Poisonous: White Snakeroot contains the toxin tremetol. When the plants are consumed by cattle, the meat and milk become contaminated with the toxin. When milk or meat containing the toxin is consumed, the poison is passed onto humans. If consumed in large enough quantities, it can cause tremetol poisoning in humans. The poisoning is also called milk sickness, as humans often ingested the toxin by drinking the milk of cows that had eaten Snakeroot.

During the early 19th century, when large numbers of European Americans from the East, who were unfamiliar with Snakeroot, began settling in the plant's habitat of the Midwest and Upper South, many thousands were killed by milk sickness. Notably, milk sickness was the cause of death in 1818 of Abraham Lincoln's mother. http://en.wikipedia.org/wiki/Ageratina_altissima

Coltsfoot


  • Resemble dandelions but appear in early spring before Dandelions appear. 
  • The leaves (resemble a colt's foot), do not appear usually until after the seeds are set. Thus, the flowers appear on stems with no apparent leaves, and the later appearing leaves then wither and die during the season without seeming to set flowers... hence the country nickname “Son before Father”
  • Typically between 10 - 30 cm in height. 
  • Has been used in herbal medicine for its purported cough-suppressing effects. 
  • In the days before most people could read and write, shops identified themselves with symbols – three golden balls for the pawnbroker, a red and white striped pole for the barber, the yellow Coltsfoot for the herbalist.

Dandelion

I came across these interesting questions (on the web) that someone had asked, followed by their observations:
1. How do the yellow petals of dandelions become those white fluffy things?
2. How long does the transformation take?
3. Does it take place only at night?
I have examined hundreds of Dandelions during the season that turn from yellow to white. I have NEVER found a transitional stage! They are always completely yellow, flowerish or completely white, parachutish.

If you're curious what the biologist's answer was, here's the link...

Wild Burdock (aka Wild Rhubarb)

  • First year plants have wavy green leaves in basal rosettes on the ground. 
  • Plants usually flower during the second year, but sometimes the flowers do not emerge until the third or forth year of growth.
  • A single plant produces 15,000 seeds on average, but yields of 200,000 to 400,000 seeds have been reported.
  • Toxicity: Common burdock is considered toxic due to potential diuretic effects, and there are reports of allergic reactions when the hooked bristles of burs lodge under the surface of the skin.
  • Velcro was inspired by the tiny hooks on the burs of this plant that stick to fur and clothing, similar to the sticky side of Velcro. www.oardc.ohio-state.edu/weedguide/singlerecord.asp?id=900

Bull Thistle


  • "Our" spiniest thistle.
  • A biennial, it produces a rosette of leaves the first year, and an upright flowering stalk the second year.
  • The "thistledown" , or bristles on the fruits, serve as parachutes to carry the light seeds.

Wild Parsnip

  • Also known as “Poison Parsnip”.
  • Looks much like a slightly larger version of the well-known “Queen Anne’s Lace” but with yellow rather than white blooms.
  • Unlike other better known toxic plants, like poison ivy, which depend on our immune response to cause their discomfort, this plant is just plain corrosive! ...causing skin burns and discoloration which can last from weeks to months on human skin.
