5 things to do this weekend, including free yoga and 'Hamilton' at Citizens Bank Opera House

My friends, I hope you’re wearing green right now. It’s March in Boston, baby. From now through March 17, it’s officially acceptable — nay, encouraged — to wear Celtics caps and jerseys to work, to let the bartender dye your beer green, to load up on shamrock accessories, and, dear god, to pray that Dunkin’ brings back the Shamrock Macchiato. Shhh. Don’t fight it. This is who we are. Now let’s dive into a weekend of green plants, blue men and more.

Get ready to be engulfed in green this weekend at the Utopia Horticulture & Epicurean Festival. The fest will be jam-packed with plants, flowers and culinary delights. From learning about sushi to making your own terrariums — if it has to do with green thumbs or epicurean delights, it’s here. Think four days of workshops like “Haute Caviar & Bubbles,” “Hands On: Grazing Board,” an interactive sushi lunch paired with Stellwagen beer and how to plant a window sill herb box. (Workshops vary in price.) Meanwhile, up on the demonstration stage, learn from pros like Matt King of Legal Sea Foods or Elle Simone Scott of America's Test Kitchen. Your next dinner party is going to be lit.

What did I tell you about wearing that green? This weekend, you can catch two stages of live music at Harpoon St. Patrick's Festival. The pre-St. Patty’s party takes place under heated tents by the brewery with plenty of beer, food and live music. The fun kicks off on Friday at 6 p.m. with local bands Comanchero, Colum Cille Pipes & Drums, Joshua Tree and 7 Day Weekend. Day Two starts at noon with music by Kier Byrnes, Dicey Riley, Howl at the Moon Dueling Pianos and more.

Stretch it out and clear your mind in a free Saturday morning yoga class at Boynton Yards in Somerville. Boynton, located within one mile of Cambridge's Kendall Square, is a mixed-use urban development site with a community center and public green space where science and culture merge. All ages and skill levels are welcome to join this Saturday’s yoga class. Just bring your own mat and get ready to savasana (my favorite pose).

“Alexander Hamilton. My name is Alexander Hamilton. And there's a million things I haven't done! But just you wait, just you wait!” Sorry, I can’t not break into song when I see the name “Hamilton.” You know the songs, you’re obsessed already, and now you have the chance to see the iconic play that reframes the story of the nation’s founding fathers in Boston. Grab the crew and alert the fam because “Hamilton” rocks the Citizens Bank Opera House through next weekend.

I can’t be the only one who thinks of Tobias Fünke in “Arrested Development” when I hear “Blue Man Group.” Please let one of them be wearing cut-off jean shorts and arguing with Jason Bateman. Expect beats, unique instruments and three blue dudes during this evening of entertainment at the Charles Playhouse.
