Crazy for Locoweeds! Meet the White Point-Vetch

May 24, 2024

After a longer than planned for blog break, I’m glad to be back and sharing a few pages from my nature journal.  Beginning in April, the riot of wildflowers popping up everywhere has, and still keeps me scurrying about my backyard, the “back 40,” and local hiking trails just to refresh my memory about familiar plant species while searching for new discoveries. I’ve been sketching daily, learning about new-to-me plants, and growing my knowledge about favorites.  

Recording first seasonal sightings, it’s interesting to compare previous years’ emergence and abundance, and wonder why timings vary. For example, last year the white-stemmed evening primrose (Oenothera albicaulis) blanketed the hillsides with white; this year those beautiful white blooms have been scarce. Last year the tall crowded flower stems of White Point-Vetch (Oxytropis sericea) were few and far between. This year an explosion of these graceful plants that belong in the pea family (Fabaceae) began blooming in April and are still going strong! 

White Point-Vetch, also called white locoweed, whitepoint crazyweed, and silky crazyweed, makes a striking bouquet that glows like a bright light as it blooms along tall flower stalks 15+ inches above bare brown ground. New stems push up through multiple dried stems packed with last year’s empty seedpods. But it’s obvious this species is an aggressive re-seeder; there are so many new plants this year where last year there were none! 

It’s been a spectacular show!

Enjoying researching this species, dissecting a few fresh flowers, and searching for remnant seeds in the dried pods, kept me delving deep into the bits and pieces of what defines this group of plants. This large family, which houses well over 10,000 species world-wide, includes peas, acacias, mimosas, and licorice (see the list below for more residents). 

But one species at a time, please! Actually the locoweeds, which fall into the genera Oxytropis (like the White Point-Vetch) and Astragalus, contain over 600 species world-wide, 21 of which grow in the U.S. Many plants in these two genera are toxic, particularly to domestic ungulates. More about the toxin and what happens when these animals ingest even small quantities, along with other interesting facts are described on my two journal pages. ……

There is so much more to learn about this important family of plants, but I’ll save that for another post. 

Thanks for stopping by and have a safe and happy Memorial Day weekend!
