The Amannia Coccinea is a species of flowering plant that’s part of the Loosestrife family(1). This plant is known by several names like the Valley Redstem, the Scarlet Toothcup, and the Purple Ammannia(1). These flowers are mainly found in dense, moist areas like riverbanks, ponds, and in other weedy areas. Some people use these plants as annual herbs. Another fact is this flower is very native and hasn’t been introduced in any other country. these flowers bloom around the months of July and September and can grow to 8-24 inches tall. When it’s growing in water, the stem starts to get spongy(2).
Animals don’t interact with the plant because of the toxins that it creates in the urinary track and could cause kidney stones. This was tested on a rat to see if it would affect its urine and it did. Humans use this plant as “herbal Remedies”. People will ground them up and the fruit that’s inside them will cut them open and take the liquids out(3).
