A Wealth of Weeds

Have you heard the one about the weird lady who walks around her yard, staring at the ground? Hey, wait a minute. That’s me. As if I didn’t already have my share of quirk, this is my new favorite hobby–except I’m not staring at the ground, I’m staring at lawn weeds. Much more normal, you see.

Why the sudden interest in weeds? Well, first off, it’s not sudden. Happily, a few years ago, a friend mentioned a name to me: Rosemary Gladstar. (Thanks, DMC!) Unhappily, I forgot this all-important name until a few months ago, when I came across a video of Gladstar discussing Elderberry. (I’ve since become addicted to her herbalism teachings and would like to grow up to be her one day.)

If I could pick one of Rosemary Gladstar’s most meaningful lessons regarding common weeds, it would be this. When the colonists left their homelands to come to North America, they only carried their most valuable possessions with them. As Gladstar says, “A prize that always went was seeds…. So, the plants that we are out there digging frantically to get out of our gardens were carefully brought over because of their edible and medicinal properties and because they had a tenacity–they would grow. So, some of our most valuable plants are our weedy species.” (Abridged quote taken from Gladstar’s video on History of Herbalism in America.)

If for no other reason, this marks weeds as something to be celebrated. Still not convinced? Here are a wealth of other reasons: (I’ll alphabetize the following list of common lawn weeds, because I’m also that kind of weird.)

*Note: Some weeds are poisonous, so you should never consume or use any weed medicinally if you aren’t completely sure of its identification. Also, I’m not an herbalist or medical professional of any kind. I’m offering this information purely to help develop an appreciation for weeds. If you’d like to learn more, I’d suggest checking with an herbalist and, also, discussing any new herbal/weedy habits with your doctor.

Purslane (Portulaca oleracea)

By Forest & Kim Starr – httpwww.biolib.czenimageid52483, CC BY 3.0,

The hairy-stemmed spurge has (as the name suggests) hairs on its stems and also leaks a milky white substance when stems are broken. (*Note: a milky substance like this is often nature’s way of warning us that something isn’t safe to consume.)

Medicinal uses: helps treat insect bites or stings, skin ailments such as psoriasis. Immune booster, supports heart health and may help prevent headaches. May also be useful in treating Asthma and Type II Diabetes (helps support the body’s insulin supply).

So, there you go. Not a complete list, by any means, and only a teaser of information about each, but I hope it demonstrates just how worthy weeds can be. As for my lawn, I’ve decided I’ll no longer hang my head in embarrassment when the weeds show up. It’s much more fun to celebrate their arrival.

By the way, in case you’d like to continue learning about wild edibles, here’s a post that another blogger reached out to share with me: 62 Edible Wild Plants…. Lots of really useful information in there! (Thanks, Colin!)
