SCV Outdoor Report: Weeds

Milk Thistle has built-in protection.

After 27 years of marriage, my husband has learned it is dangerous to set me loose in a bookstore without supervision.  You never know what I’m going to come home with.

 

This week I splurged and spent $40 on just one book, “Weeds of the West”.  (Yeah, I know what you’re thinking, but it’s not about THAT kind of weed.)  I bought it because it was chock full of great photographs that I can use to help me identify plants in the field.

 

How do we define what is a weed?  Is it simply a plant growing where it is not wanted, like a dandelion in a carefully manicured lawn?  According to the book’s authors, a weed can be defined as:  “A plant that interferes with management objectives for a give area of land at a given point in time.”  I like this definition because it is dynamic rather than static and reminds us that just because a plant is a considered weed in one location and at one time does not mean it is a weed everywhere.  And even if it is a weed, it may possess some positive qualities.

California poppies are invasive weeds in other parts of the world.

As an example of place-dependence, consider the Black mustard and the California poppy.  Black mustard is a native from Europe, supposedly introduced by early Spanish explorers, who scattered the seeds to mark their route along the El Camino Real.  We consider this to be a weed.  And the California poppy is a native plant and became our official our state flower in 1903.  It is considered an invasive species in other parts of the world, including Australia, parts of South America and Spain.

 

As an example of a nasty plant with at least one positive quality, consider the Milk thistle.  A native of the Mediterranean region of Europe, it is considered an invasive weed in California because it crowds out other native plants.  And when it encroaches on the trail, I have found it to be a nasty prickly bugger.  But some scientific studies suggest that silymarin, one of the chemicals in Milk thistle, can protect the liver from damage caused by toxins, alcohol, and acetaminophen.  So is Milk thistle a medicinal plant, a weed, or just personally out to get me?

 

So I end this with one additional question for you to ponder:  if we define a weed as a plant out of place, who decides which place is the right place?
