Asclepias syriaca

more time to produce pods, or have a more extensive root system to acquire nutrients necessary for pod production. Some of the variability in pod numbers observed for may be because milkweeds produce stems periodically thorough the growing season, so during the summer, different stems may be in different life stages. Milkweed also grows from underground rhizomes, which may produce clones of the parent plant nearby (“Milkweed Fact Sheet”, n.d.). Because of this, with the hula-hoop method we used, the samples were likely not independent. Another source of variation may be due to a trade-off between the size of the seeds in the different sized seedpods and the dispersal ability. Morse and Schmitt (1985) found that in the common milkweed Asclepias syriaca, there was a negative correlation between seed size and dispersal ability, with smaller seeds dispersing further, and larger seeds having more success in germination. They found a large diversity in the morphology of the seeds among clones and the pods within clones, so seed, and perhaps pod size, is not genetically determined by a clear mechanism. This would make a trade-off between growth and reproductive resource allotment difficult to detect. There is no statistically significant relationship between the height of the milkweed and its duration latex flow in our study. This contrasts with results obtained by Züst, Rasmann, and Agrawal (2015), which found a positive relationship between plant growth and latex production,…

Ronnie Estes Rocky Mountain Flora March 31, 2015 Milkweed Description Common Milkweed, Asclepias syriaca, is a biennial to perennial herb in the family Asclepiadaceae. This forb usually has a solitary, simple stem, 0.5-1.8 meters (1.5-6 feet) tall, though clumps of multiple stems may be found. Milkweed may also be rhizomatous through the growing season. This may be evident with stems being at different life stages throughout the summer. The leaves are opposite, ovate, and 5-25 centimeters (2-10…

So the seeds themselves while making up nearly the entire mass of the rosehip do not actually contain the most vitamin c. The skin on the other hand does, which is why Rosehips should be boiled whole in a pot of water to get the most vitamins, and antioxidants as possible from the fruit. Slippery Elm was used by several different Native American tribes’ fir soothing respiratory and digestive tracts. “A tea from the inner bark was utilized as a laxative and to help ease labor pains (Cole 30)”.…
