Plant Fact Of The Week III April 11, 2011

Someone had recommended last week that I should make this week’s plant fact a Public Service Announcement.  So  I did. 🙂

This week’s plant fact is brought to you by Toxicodendron radicans, also known as poison ivy.

PLANT FACT OF THE WEEK: Poison ivy (and its relations poison oak and poison sumac) contain the oil urushiol. Late winter to early spring is the absolute worst time to get poison ivy. Poison ivy, like most other deciduous plants, tend to go dormant when temperatures begin to cool off as we head into winter time. This being said, even though the plant may look dead, it is alive and well. During the winter, the plant builds up the urushiol oil in its stem until spring time, when it then spreads the urushiol through its newly formed leaves. Do not think that you are immune to poison ivy because you have never contracted it. Some may have a tolerance more than others, but if one is repeatedly exposed to it, one is bound to get a rude awakening.

Edit To Add:   J.P.  brought up a very good point–poison ivy can look like a nasty hairy vine that lacks leaves (it is still just as bothersome as its leaf-bearing counterpart) and may hide in other shrubs and plants, so be cautious when hiking through woods and be aware of your surroundings.

This week’s fact is brought to you by the genus Narcissus, and is a perfect segway for next week’s plant (everyone’s personal favorite): poison ivy.

PLANT FACT OF THE WEEK: Daffodils are known to cause skin reactions called “daffodil itch.” It usually results in dryness, scaliness and cracks on the hands due to the calcium oxalate (a key component found in the formation of kidney stones) that is present in the sap.

I know that this will be a blog to catalog my experiences as an intern, but since that will not start until July–I figured I would get into a regular habit of posting here anyways.

To get me into a routine of posting, I think I will post one plant fact per week. I have a lot to do between now and the end of the semester, so posting one plant fact a day seems  a bit unreasonable. It is however possible to do one fact per week.

I know it’s the end of the week (Friday will be upon us tomorrow), but one fact late is better than one fact never to have come.

In honor of Spring, this week’s plant fact of the week is brought to you by the genus Tulipa.

PLANT FACT OF THE WEEK: Contrary to popular belief, tulips did not originate from Holland, but from Turkey. The tulip was introduced to Holland in 1554.
