Even if you're not the woodsy type, it can | be found alongside paths in city parks and etc, so good to know | how to recognize. | ChrisMarshallNY wrote: | I have done pretty well, on this test (my wife showed it to me, | last year). | | We grow poison ivy as a cash crop, around here. You learn to | recognize it. | trynewideas wrote: | A cash crop for what? What sells, why, and to whom? | ChrisMarshallNY wrote: | It was a joke. | | It is _everywhere_. I once did a photo essay of a local | abandoned insane asylum. Some of the buildings are covered | with poison ivy, like English ivy (often, both). | | Looks pretty in the fall, though. | | ProTip: Don't burn it. | x3n0ph3n3 wrote: | I recently tried a soup in Korea (ocdalg or oht-tak) made from | Toxicodendron vernicifluum before knowing what it was. The people | I was with were very insistent that I take a pill to neutralize | the allergen (urushiol, found also in poison ivy, is technically | an allergen rather than a toxin) before I ate it. | | Not everyone reacts to it, but when they do, it's pretty bad. The | others I ate with have no reaction to it at all. | bjt2n3904 wrote: | The trick someone taught me for identifying poison ivy (I've got | it ALL over my yard) was... | | 1) Irregular leaf shape. The leaves just don't know how to grow. | Straight edge? Jagged edge? Both, neither? | | 2) The three leaves form a T-shape, with the center leaf jutting | out. | ChrisMarshallNY wrote: | Kudzu looks similar (but bigger). | | Kudzu has its own issues, but it isn't a blistering agent. | | https://www.nature.org/en-us/about-us/where-we-work/united-s... | trynewideas wrote: | To save you the clicking, if you answer "No" to every picture, | you score 35/55 ("Not bad!"). | evan_ wrote: | "Leaves of three, let it be" | greenbit wrote: | It's good to recognize the vines that run up tree trunks as well. | Easiest when they have leaves, but they don't always have leaves | especially in shady areas. The bigger vines tend to have a hairy | or bushy look, lots of little root-hair like bits, that seem to | help it cling to the tree bark, and these seem to have a reddish | hue about them. | marymkearney wrote: | Mostly of interest to readers in North America and China, where | Toxicodendron radicans is generally found. | | Scores: 50/55, then 53/55, then 55/55. Better to over-ID than | under-ID (ask me how I know). | dgacmu wrote: | Ditto from a fellow "learned the hard way" poison ivy ID | fanatic. 52/55 - three false positives, no false negatives, | exactly as I'd prefer. | | Well worth studying - and its habitat is spreading over time. ___________________________________________________________________ (page generated 2023-02-03 23:00 UTC)
