Only in Minnesota would we celebrate a weed. This peculiar celebration marks the auspicious day when Harriet Godfrey first brought dandelion seeds to St. Anthony Falls in 1849, forever altering the rituals of lawn care in the Twin Cities. (And for you, dear Harriet, we have the seeds of a lovely little bush called “buckthorn.” Enjoy.) Events include making dandelion jewelry and costumed tours of the Ard Godfrey House. 1p.m. - 4p.m.
