<Alt Text 1 of 2> (Photo Note: the two specimens in today's post look different because they are different ages and emerged at different times in winter/spring.) Today’s wild plant of the week is one that that you most likely have seen but disregarded as ‘just a weed’. In my copy of ‘Weeds of Southern Turfgrasses’ which was required reading in the Horticulture program at Fayetteville Tech Community College this plant is called Spiny Sowthistle (Sonchus asper). Other sources call this plant Prickly Sowthistle, Rough Milk Thistle, Sharp-Fringed Sow Thistle or Spiny-leaved Sow-thistle but despite all common names this plant is not a true Thistle. While it is true that Spiny Sowthistle is in the Aster family just like true thistle, unlike true thistles it, it is in the Chicory grouping (Chichorieae). In general Spiny Sowthistle is considered a winter annual or a winter biennial herb depending on where it is found and the conditions under which its seeds germinated. In an urban environment these plants do not get all that tall however they can be up to six and a half feet tall under the right conditions. Spiny Sowthistle is native to North Africa, Europe and Western Asia, and if intentionally cultivated one should take care to not allow it to go to seed as it can become a problem and due to this it is considered a noxious invasive weed in a few places. The name ‘Sowthistle’ comes from the plant being used at one point or another as feed for pigs. The botanical Latin word ‘Sonchus’ comes from the Greek name for the plant and roughly translates as ‘hollow’ which has to do with the plant’s hollow stems. The specific epithet ‘asper’ means ‘rough’. Now with that said, let’s look at how this plant can be used. <Alt Text 1 of 2>
<Alt Text 2 of 2> From several sources I have found that the ethnobotany of this plant is very interesting in North America (despite this plant not being native) specifically as the Iroquois used it as a sedative and a pediatric aid for fussy babies. The Luiseno and Pima used it as a food item for its greens; while the Mohave considered it a starvation food and the tender shoots were roasted and eaten. The Navajo used it as a heart medication and the plant was smoked or taken internally to handle heart palpitations. Oddly the Navajo also considered the plant poisonous for some reason that does not seem to align with other information. For general foraging purposes, the good news is that most if not all of the Sowthistles you will encounter in North America are safe to eat, even in the case of the Spiny Sowthistle it is safe and the prickles are not actually dangerous. As a general rule you want to go for younger more tender leaves as the older ones can be bitter so it’s wise to only harvest from plants less than a foot tall. The prickly bits can be trimmed off of course with some careful paring knife work and the greens will cook down to a soft texture very easily. If you intend to store the greens in the refrigerator for a few days leave the prickly bits on. Typically I prefer to use this green in one of two soups, homemade Minestrone, or as a flavor additive to Kale-Bean soup. I also use it in a special version of Pasta e Fagioli because its flavor of these greens can take the dish to new places. <Alt Text 2 of 2>
